Dr Michael King

Chair of the Department of Chemistry at GWU

Dr Michael King is Chair of the Department of Chemistry at GWU, a private, coeducational research university located in Washington DC. The Department has two benchtop Spinsolve NMR spectrometers from Magritek for the physical/analytical chemistry and organic chemistry laboratories. In Dr King’s class, it is used for quantitative organic analysis. The experiments performed by his students utilize the basic 1D proton mode; loading samples, obtaining spectra and then use the MNova software to clean up and analyze the resultant data.  Every year about 160 students at GWU take this class, with each practical lab session having around 14 students. In the lab class each student is provided with solid and liquid unknowns and they have to determine from spectroscopy (NMR, IR) the structure of both.

“What I like about the Spinsolve and about the software is the high throughput.”

Commenting on why he likes the Spinsolve for teaching, Dr King says, ”What I like about the Spinsolve and about the software is the high throughput.  Obtaining the spectrum takes only a few minutes – less time than making the solution and putting it into the NMR tube.  Place the sample tube in the instrument; then run a few scans, we typically do 16, and the students have a high quality spectrum.  In terms of preparation we just run a short few minute shim at the start of lab session and it’s good for the rest of the day.”

Dr Vania De Paoli

Professor in the Department of Chemistry at Cleveland State University, Ohio 

Dr Vania De Paoli is an associate college lecturer in the Department of Chemistry at Cleveland State University in Ohio. Prior to investing in the Magritek benchtop NMR spectrometer, students‘ practical options were limited to the measurement of melting points and refractive index. Old gas chromatographs were so old, they were no longer functional. Students were not experiencing anything close to life in a modern organic chemistry laboratory. As Dr De Paoli says, the Spinsolve has changed this position immensely. “It is a small system, portable and lightweight. It is quickly ready to use allowing the students to have a real NMR analysis experience (they prepare the samples in standard NMR tubes, add the solvent and record the spectra in similar ways to a research grade NMR). The spectra are of good quality. The software is friendly and, overall, Spinsolve is readily affordable.”

Dr Harald Baumgartner

Coordinator of Evening Chemistry Classes

HTBLA Wels is a higher technical vocational college of chemistry in Austria. Here, Dr Harald Baumgartner is responsible for the instrumental analytical laboratory.  NMR has been part of the curriculum for some years. However, this was through a very old 1H-60 MHz NMR. New instruments usually require fillings of expensive liquid helium for cooling the magnet. Dr Baumgartner says “Compared to the old 60 MHz spectrometer, the Magritek Spinsolve benchtop spectrometer is so much easier to use. It is software-based so collecting and processing data is quite straightforward.  As well as 1H spectra, our Spinsolve allows us to measure more complex spectra including 13C-spectra. Even 2-dimensional experiments are now available to the students.”

Dr Maria Vogt

Professor of Chemistry at Bloomfield College

Dr Maria Vogt is Professor of Chemistry at Bloomfield College, an undergraduate college in New Jersey. “NMR is essential at many levels of chemistry. It is essential in graduate school and industries such as foods and pharmaceuticals. Providing a foundation in the analysis of simple samples by NMR at the undergraduate level will help prepare my students for the interpretation of the much more complex spectra of more complex molecules. The more hands-on experiences the kids get as undergraduates, the better they are prepared for further studies and/or the workplace.”

“The more hands-on experiences the kids get as undergraduates, the better they are prepared for further studies and/or the workplace.”

Purchase costs, prohibitive maintenance bills and complex operating conditions all made the thoughts of obtaining an NMR for undergraduates all but impossible. As she says, “For many years, no one was interested in manufacturing a simple NMR for undergraduate student use. It was all about the big-bucks systems. In recent years, however, I became aware of three or four such instruments becoming available. I looked into them but, quite frankly, was less than thrilled with their performance until Magritek came into the picture. Magritek’s Spinsolve is by far the easiest instrument to use. It is also extremely fast, with an excellent spectrum generated and printed out in a minute or two. The software is intuitive. Over my many years in research and teaching laboratories, I have seen instruments get more and more complex with even more complex software. These instruments are very powerful and can do a lot of stuff. However, they are less than user-friendly. First and foremost, I am interested in teaching my students as much as possible. I am not big on demos. I want the kids to run their own spectra and then analyze the results. Lab work should be fun. Generating and analyzing your own spectrum is a lot of fun. Most students really don’t like solving puzzles. However, I must say that they certainly enjoyed their experiences with the Spinsolve.”

Dr Kaveh Azimi

Chairman of the Chemistry Department at Tarrant County College

Chemistry Department Chairman, Dr Kaveh Azimi, and staff, are enthusiastic about their decision. “Faculty selected Spinsolve spectrometer for many reasons. Its compact size is ideal for a teaching laboratory where space is at a premium. Maintenance free operation thanks to the permanent magnet design means there is no need for cryogen fills saving valuable resources. The simplicity of sample preparation and the fact that the system uses standard 5 mm NMR sample tubes make this an ideal instrument for a teaching lab. The quality of spectra is excellent and to have the option of a 13C upgrade increases the value of this initial investment.”

“We were “magnetized” by Spinsolve’s simplicity of operation and the superior quality of spectral output during the hands-on instrument demonstration. The Spinsolve took us for a surprising spin!”

Dr Paul Wiget

Assistant Professor of Chemistry and Biochemistry Howard School of Arts and Sciences at Samford University, Birmingham

Dr Paul Wiget says “the greatest benefit of the system is its ease of use and low-level of training for student operation. We are also very fond of no longer needing an air source for spinning. The instrument is very fast and reliable compared to the old, larger, 60 MHz instrument we had. The requirement of consistent spin and the finicky nature of the software made the instrument less practical for student use, and very challenging for research purposes.”

“The greatest benefit of the system is its ease of use and low-level of training for student operation.”

“With the simultaneous 19F and 1H “nested” monitoring scripts, we can get reinforcing data by monitoring the reaction progress via two nuclei instead of just one. Additionally, when the dispersion issue arises during that experiment, we no longer have to abandon the more substituted alcohols because we can simply monitor the reaction via the 19F spectra.”

Meredith Moses

Assistant Professor of Chemistry at the College of Humanities and Sciences at Virginia Commonwealth University

Meredith Moses teaches a hands-on approach: “We use the NMR so that the students know and understand about NMR.  If they go to grad school or industry, they need to be familiar with it.  Also, they are expected to be able to analyze spectra for their second semester (lecture) final exam.  I like them to produce spectra of their own compounds so they know if they got the right product or not.  Some instructors just hand out spectra of one groups’ sample or use literature spectra, but that somewhat defeats the purpose of a practical course.  Students should know how good THEIR product is.”

Dr Jonathan Harburn

Lecturer of Medicinal Chemistry at the School of Medicine, Pharmacy and Health at Durham University

Dr Jonathan Harburn says “It has a small footprint; it is robust (student friendly); and is inexpensive in comparison to purchase and operating costs for a high field NMR. In the near future, we are going to place this in series with our Syrris Africa Microfluidic System for online NMR of new chemical entity library generation under flow conditions. This would be tandem with online LC/MS and would give the opportunity to have very fast synthesis and analysis of hundreds of compounds overnight. Setup of Magritek will be very easy in comparison to a high field, supercooled NMR.”

Dr Alan Kenwright

Reader in the Department of Chemistry at Durham University

Dr Alan Kenwright: “being able to do measurements in the relatively low magnetic field (43 MHz) used by Magritek’s Spinsolve is a big advantage for us, particularly as the field it uses it not very different to the field actually used in many hospital MRI scanners.”

“…real time reaction monitoring using flow-through NMR techniques.  This is not a new idea, but has previously been limited by the requirement to bring the reaction close to a large (static) and expensive NMR spectrometer.  The small size of the Spinsolve means that we can mount it on a trolley with an uninterruptible power supply (UPS) and move it around the department – taking the spectrometer to the fume cupboard where the reaction is being carried out.  Working with partners in industry, we are evaluating this in parallel with small footprint Mass Spectrometry to see what relevance this approach might have not just in the University laboratory but also in pilot plants and possibly even at production scale.”

“…the opportunities for students to get involved “hands-on” become less, so exposing them to a robust, simple instrument they can use themselves is a big plus.”

“Students used to miss the link from theory to practical use. Now my groups can have a hands-on experience and understand the value of NMR to the synthetic chemist. My second semester first-year students are taken through the basics of using Spinsolve. They make a product (paracetamol); run it on the NMR; acquire and process the data. Some of our more high achieving undergraduate students go a stage further with a six week research project where they are introduced to spectroscopy – IR, NMR and GC-MS. Each student is allowed to choose their own project. For example it could to study different reactions of benzaldehyde. They will analyse the products they synthesise to look at variations in substitution products. They are taught to use multiple techniques to confirm what they have made and the Spinsolve NMR machine is key to achieving this.”

“The versatility of Spinsolve is just great. It gives us the flexibility we need. Students and staff alike are very pleased to have access to it.”

“Previous to adding NMR capability, we introduced our students to IR spectroscopy and gas chromatography. When we saw the performance and price of the Spinsolve Benchtop NMR spectrometer from Magritek, we saw our opportunity to fulfil another of our goals.  In particular, we were impressed with the durability and robustness of the machine. The range of different applications such as the 2D capability was most important when we came to make our purchase decision.”

Dr Joseph Hornack

Director of the Magnetic Resonance Laboratory at the Rochester Institute of Technology

“We chose the Spinsolve NMR for use in an Instrumental Analysis laboratory with 90 students (mostly chemical engineers).  In addition to NMR, students get exposure to UV-Vis, fluorescence, AA, and IR spectroscopies.  We wanted an NMR with a low operating cost which could be sited in the lab, and leave the students with a positive NMR experience.  Just like with the Terranova from Magritek, the Spinsolve scores high points for ease of use, both in collecting and processing the data.  Shimming is easy and does not need to be performed on each sample.  The resolution is sufficient for students to easily analyze 1- and 2-D H spectra of small molecules. It can be used to measure spin-lattice and spin-spin relaxation times at 40 MHz that we cannot take with other instruments.”

Regius Chair of Chemistry in the School of Chemistry at the University of Glasgow

“We now use the Magritek Spinsolve in the ‘flow’ mode that we developed in my lab. For our work, this is important as it allows us to look at reaction dynamics. We can run entire reactions (no need for deuterated solvent) or look at things in real time; we can adjust reaction outcomes as a function of NMR. This makes for a very flexible system.”

“Despite the low field of the magnet, Spinsolve has remarkable sensitivity and stability.”

Dr Michael Maiwald

Head of Process Analytical Chemistry Division at the BAM Institute

“We were impressed with the spectra – the symmetrical line shape and narrow line width was achieved even in technical mixtures. This is due to the use of Halbach magnets. The stability we observed over a given period of time without preparing the instruments was extremely good. We have seen that the Spinsolve remains working in specification for as much as 48 h in a technical environment. Pre-magnetisation below the active region of the magnet is important to us for online measurements. As far as we see, the instrument meets this requirement.”

“This is the first time that our group has had access to NMR in our laboratories.  For a long time, our research group has been working mostly with NIR spectroscopy and, most recently, with Terahertz spectroscopy to develop new methodologies applying chemometric tools. Now we’d like to implement the NMR spectroscopy (low-field) in our research starting with analysis of fuel. We believe that the benefits of using NMR will be on the speed of analysis (comparing to physical-chemicals essays for fuels, which are laborious and time consuming), the cost of analysis and the possibility of automation sometime in the future.”

Dr Theo Dingemans: “we use NMR to understand the structure/product confirmation of organic small molecules and polymers. Sometimes we use it to follow progress of the reactions. We chose the Spinsolve system because it’s very easy to use. It requires no cryogens and very little maintenance. When we need to use the high resolution NMR system, this requires sign-up and is on the other side of campus. Now we can do chemistry in the lab: take a sample and analyse it immediately. It improves our productivity in the lab.”

Dr Jeroen Geuens

Member of the Centre of Expertise on Sustainable Chemistry (CESC) based in Antwerp at the Karel de Grote University College

“In teaching, our 2nd and 3rd year students (professional bachelor in chemistry) are using the Spinsolve during their lab sessions for organic chemistry. They synthesize organic molecules such as tertiary butyl chloride, aspirin, and isopentyl acetate. They purify their products and then analyze them using NMR and FTIR. In total, approximately 80 students are using the Spinsolve during the organic chemistry lab each year. For research, CESC is studying the valorization of organic waste streams. The standard treatment procedure for an unknown waste sample is accelerated solvent extraction (ASE) using solvents with different polarities. After the solvent is evaporated, the different fractions are analyzed by means of NMR, FTIR, and GC-MS. There are also three oleochemical projects running, i.e. projects concerning vegetable oils. For these projects, we implemented a method to determine the iodine value of an oil with the Spinsolve. The standard method to measure the iodine value implies a titration using the Hanus iodine solution which has to be prepared fresh. Moreover, a standard solution of Na2S2O3 is needed as well as glacial acetic acid which all takes considerable time. When using the Spinsolve, no solvents or chemicals are needed. The only thing you have to do is put the oil in a NMR tube, keep yourself busy for 21 minutes, and return to the apparatus for the result.”
