Chromatographic analysis for peptide drugs are important for ensuring product quality and safety. In this article, we introduce our solutions for peptide drug analysis, including the chiral analysis of protected amino acids, the determination of peptide related substances, the analysis of peptide aggregates by SEC, and the evaluation of amino acid ratios using the Welch Ultisil Amino Acid Method Kit.

Herbicides are an essential tool in weed management, and chirality greatly affects their efficacy. In this article, we explore the chiral separation of two herbicides: 2-(2-chlorophenoxy)propanoic acid and dimethenamid, using Welch Blossmate chiral columns.

Alcohols and diols are among the most common functionalized intermediates in organic synthesis and pharmaceutical development, and chirality can influence their efficacy greatly. In this article, we introduce applications on the chiral separation of several typical alcohols and diol using Blossmate chiral columns.
