Cover Story
Separating and quantifying both volatile and nonvolatile compounds in complex mixtures is a costly and time-consuming process presenting significant technical challenges. Fabrice Gritti from the Instrument, Core Research, Fundamental Group at Waters Corporation discusses his team’s unique solution to this problem, combining high-vacuum technology and low-density fluid chromatography (LDFC) with carbon dioxide as a mobile phase for a rapid and complete baseline separation of both volatile and nonvolatile compounds on a single instrument, single column, and a single run without the associated loss of resolution.
Incognito offers his advice on how to be a leader rather than a manager.
Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) is the standard method to separate samples by molecular size. In protein analysis, size-exclusion chromatography is either applied to detect and quantify aggregation, or to measure the complete molar mass distribution. However, method development is not trivial and the choice of suitable detection options is crucial.
This article describes the evolution of traditional solid-phase extraction (SPE) into new techniques that are customized to the characteristics of specific matrices, including the removal of β-glucuronidase from urine samples and the removal of phospholipids and proteins from plasma samples.
