Non-targeted metabolite profiling by ultrahigh-performance liquid chromatography coupled with mass spectrometry (UHPLC–MS) is a powerful technique to investigate the influence of genetic and environmental influence on metabolic phenotype in plants. The approach offers an unbiased and in-depth analysis that can reveal molecular markers of desirable phenotypic traits which can be complementary to genetic markers in plant breeding efforts. Here, the power of non-targeted metabolite profiling is illustrated in a study focused on the determination of molecular markers in malting barley that are predictive of desirable malting quality for brewing applications.

In the first two parts of this series we have looked at where and how a CDS fitted into a regulated laboratory and the overall requirements for the architecture of a future system. In this part we focus on new electronic ways of working for chromatographic analysis.

A farewell letter from long-time LCGC columnist Ron Majors.

Particulate matter from the sample or the system can cause havoc in the chromatogram.

A short guide to the do’s, don’ts and gotcha’s of eluent preparation for everyday HPLC

This fourth and last installment in the series of “Separation Science in Drug Development” provides an overview of modern practices of Quality Control in small molecule drug development including activities such as setting specifications, method validation/transfer, release and stability testing, and authoring CMC sections of regulatory filings.

In his final “Column Watch” article, Ron Majors looks into his crystal ball and discusses future needs in the area of HPLC/UHPLC column technology and related instrumentation. He looks at where current technology may be heading and makes a prediction that monolith-based columns may still have a rightful place in the HPLC/UHPLC laboratory .This article concludes his duration as a monthly columnist for LCGC.

A tribute to Roy Eksteen, who was a great man and a great proponent of the chromatographic sciences.
