In screening for hemoglobinopathies, high-performance liquid chromatography (HPLC) achieves excellent sensitivity and specificity, while adding the very important quantitative element to the analysis.

When conducting reproducible and interference-free analysis by liquid chromatography, the purity of the solvents used, particularly the purity of water, is crucial for the sensitivity of this method, ...

The peptide research market has a verification problem. Independent testing studies have repeatedly found that peptide vials sold as research-grade frequently fail to meet their labeled purity claims.

High-Performance Liquid Chromatography (HPLC) is a sophisticated analytical chemistry technique used to separate, identify, and quantify components in a liquid mixture. It operates by pumping a ...

Daniel Zimmerli, associate scientist and lead of the Separation Science Point group, discusses how his team uses high-performance liquid chromatography (HPLC) and ultra-high performance (or pressure) ...
