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

This is the second article in this series discussing HPLC oligonucleotide separations. This article will discuss the separation of oligonucleotides and dsDNAs using a wide-pore, polymer based reversed ...

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.

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, ...
