Separating and quantifying both volatile and nonvolatile compounds in complex mixtures is a costly and time-consuming process presenting significant technical challenges. Fabrice Gritti discusses his team's 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. read more

Traditional techniques used to perform the extraction of pesticides from food matrices are time consuming, solvent intensive and can deliver inconsistent results. The need for economical, fast, reproducible testing protocols exists. Perform consistent extraction of pesticides for analytical quantitation in 10 minutes. The PLE can dramatically improve reproduciblity of results, speed and cost of extractions.

Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) is a powerful tool for determining the complete molar mass distribution of macromolecules. Recent design advances are creating new opportunities to use GPC/SEC for challenging analyses such as copolymers. In this eBook, experts discuss how several GPC/SEC methods may improve copolymer sample characterization. Learn about dual-detection methods, polymer liquid adsorption chromatography, 2D chromatography, and more.
