Applying LC-MS to Disease and Wellness Diagnosis
LCGC recently spoke with Fred E. Regnier, the John H. Law distinguished professor in the Department of Chemistry at Purdue University (West Lafayette, Indiana) and a member of LCGC's editorial advisory board. Regnier is known as an innovator and has received 45 patents related to the separation and detection of proteins and peptides. He has also done extensive work in proteomics and is the 2013 recipient of the ACS Award for Separations Science and Technology.

ALEXYS™ Neurotransmitter Analyzers
For superior sensitivity in neurotransmitter analysis, Antec provides dedicated ALEXYS Analyzers based on (U)HPLC with Electrochemical Detection (ECD) for monoamines and metabolites, GABA, Glutamate and Acetylcholine. Different instrument configurations are available to achieve highest sensitivity and/or speed of analysis using less than 10 µL of sample. For monoamines and metabolites a dual-channel HPLC/ECD system has been developed with detection limits as low as 0.2 fmol. Read more.
NMR and LC-MS Team Target Phytochemicals
The North Carolina State University Plants for Human Health Institute (PHHI) and the Dole Nutrition Research Laboratory (Kannapolis, North Carolina, USA) have collaborated to form a joint industry-academic postdoctoral fellowship, the first of its kind at the North Carolina Research Campus (NCRC).
UHPLC Front End System
Shimadzu's Nexera MP UHPLC, utilizing the SIL-30ACMP Multiplate Autosampler, is the solution for higher speeds, low carryover, better precision, and high throughput. The SIL-30ACMP features a high-speed injection (7 seconds), an outstanding injection mechanism, and near-zero carryover (0.0015% or less). In addition, a maximum of 2304 samples can be analyzed continuously, making it ideally suited as a front end for all LCMS platforms. Read more
