Detroit, MI. The department of Biochemistry and Molecular Biology at Wayne State University, located in Detroit, MI has been producing their own uninterrupted supply of nitrogen, on-site, since 2003. The University installed a PMNG membrane nitrogen generator to supply clean dry nitrogen for their Nuclear Magnetic Resonance spectroscopy, most commonly known as NMR spectroscopy.
Many types of information can be obtained from an NMR spectrum. Much like using infrared spectroscopy (IR) to identify functional groups, analysis of a NMR spectrum provides information on the number and type of chemical entities in a molecule. However, NMR provides much more information than IR.
The impact of NMR spectroscopy on the natural sciences has been substantial. It can, among other things, be used to study mixtures of analytes, to understand dynamic effects such as change in temperature and reaction mechanisms, and is an invaluable tool in understanding protein and nucleic acid structure and function. It can be applied to a wide variety of samples, both in the solution and the solid state.
Compressed Gas Technologies PMNG membrane nitrogen generators are ideally suited for laboratory applications such as NMR and LCMS because of their small foot print; low noise levels; and simplicity factor. These units only require filter changes semi-annually.
