Our annual review of products introduced at Pittcon or during the previous year

Spectroscopy interviewed Monique Chanhuot (Ecole Normale Sup?rieure, Paris, France) about her recent work using chiral liquid crystals in NMR to track changes in alanine chirality driven by alanine racemase. The hope is that, in the future, elucidations of the enzyme activity may enable the development of inhibitors and new antibiotics.

One of the most critical components to the performance of any high-field nuclear magnetic resonance (NMR) system is the NMR probe. The probe is where all of the action happens within an NMR system, and they are offered in a wide variety of sizes and configurations for different applications. The aftermarket for NMR probes, alone, is quite a sizeable market, and will continue to be a major driver of the market.

TD-NMR (Time-Domain Nuclear Magnetic Resonance) is a powerful tool for the petrochemical industry, from exploration to refining, that examines materials at the molecular level to quantify physicochemical properties.

The high-flying field of nuclear magnetic resonance (NMR), which is continuing to see strong growth as it approaches the $1 billion mark in annual market revenues, overshadows the market for low-field and fixed magnet NMR. These systems are far simpler and less expensive than the larger systems many have come to think of when they hear the term NMR. The range of applications for low-field and fixed magnet NMR is vast, which is contributing to strong growth in demand.

Combining the three techniques of LC, MS, and NMR into one integrated system provides optimal use of NMR intrument time by using information-rich MS data to automatically guide the NMR operation. Here, the authors explore just this type of system.
