In-Depth Analysis of Host Cell Protein (HCP) Impurities by LC–MS/MS to Augment Routine HCP-ELISA Testing of Biotherapeutics
LC–MS/MS has gained momentum as an orthogonal approach to ELISA for host-cell protein (HCP) analysis. LC–MS/MS can identify and quantify individual HCPs, and help ensure that no HCPs evade detection above a reportable limit.
Rapid, Efficient Quantification of Water in Solvents and Solvents in Water Using an Ionic Liquid–Based GC Column
Developing versatile, rapid, and accurate analytical techniques for the detection and quantification of water in a variety of materials remains an important and ubiquitous analytical problem. This article describes an effective and sensitive ionic liquid (IL)-based capillary gas chromatography (GC) method with thermal conductivity detection (TCD) to determine the water content in liquid samples.
