Characterizing biological processes in single cells with CE

The characterization of transcripts, proteins, peptides, and metabolites in cells is important to study disease mechanisms and develop novel therapeutics. Peter Nemes — from the George Washington University, in Washington, USA — spoke to The Column about the important role of CE–ESI and TOF-MS in this area of research.

Quantification of mycotoxins in peanut butter using SFE–SFC–MS

An on-line SFE–SFC–MS approach was successfully used to extract and analyze aflatoxin B1 and B2 from spiked peanut butter samples.

Detecting choline using IC

This article describes the performance of the AOAC Official First Action Method (AOAC Method 2012.20) chosen by SPIFAN, which uses microwave-assisted hydrolysis sample preparation followed by ion chromatography (IC) separation with suppressed conductivity detection for the determination of choline.
