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.

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.
