Measuring Moisture in Acetonitrile Using Gas Chromatography and the LUMA Vacuum Ultraviolet (VUV) Detector: Trace Levels and Beyond

The water content of organic solvents is one of the crucial properties that affect the quality of the products and the efficiency of the manufacturing processes. In many organic solvents, water is generally considered an impurity, and therefore its measurement in solvents is of importance for many industries and technologies. This is especially true, for...

TRACE LEVEL ANALYSIS OF NDMA USING GAS CHROMATOGRAPHY AND THE LUMA™ MULTI-CHANNEL VACUUM ULTRAVIOLET (VUV) DETECTOR

Mutagenic impurities, such as nitrosamines are thought to cause DNA mutations, potentially leading to cancer. Since 2018 there has been a concerted effort by various regulatory bodies i ncluding the ICH and FDA to regulate the average daily intake of nitrosamines in a wide range of drug products. This a dded scrutiny has resulted in...

Better Living Through (Flavor) Chemistry Part 1 – We Don’t Need No Separation, We Don’t Need No Flow Control

Alex Hodgson, VUV Analytics

Alex describes how GC-VUV is able to differentiate terpene isomers, and why it's possible to speed up GC run times and increase sample throughput.
