Most HPLC columns are packed with silica onto which some form of hydrophobic ligand is bonded – these columns form the vast majority of those used for modern reversed-phase HPLC. Learn more
Successful GC analysis requires careful control of carrier gas. Here, we explain how to measure and control flow rate, use constant pressure vs. constant flow, and more.

Drug discovery using high-throughput screening of discreet compounds, and the discovery of natural products with pharmacological mechanisms of action, rely on bioassay-guided fractionation analysis. Recent applications of affinity selection–mass spectrometry (AS-MS) are useful for exploring the discovery of ligands to membrane-bound proteins and RNA targets.

SPME Arrow offers higher adsorption capacity and higher mechanical robustness than traditional solid-phase microextraction (SPME). Traditional SPME also has a small linearity range. In this article, an SPME Arrow fiber and classical SPME fiber were tested for the analysis of flavor profiles for different types of beverages.
