VENTURETM A — High Performance Analytical Column for the Purification of Antibodies

Using pyrolysis-gas chromatography and mass spectrometry, scientists from Fudan University and the Putuo District Center for Disease Control and Prevention detected and quantified microplastics in newborn stool samples.

The researchers explored ways to simplify retention time calculation across LC–MS and various other chromatographic methods.

A new type of micro-gas chromatography column was fabricated using direct metal laser sintering (DMLS) to circumvent manufacturing issues faced by other micro-GC systems.

This article introduces a multi-step preparative purification workflow for synthetic peptides using liquid chromatography–mass spectrometry (LC–MS). The process involves optimizing separation conditions, scaling-up, fractionating, and confirming purity and recovery, using a single LC–MS system. High purity and recovery rates for synthetic peptides such as parathormone (PTH) are achieved. The method allows efficient purification and accurate confirmation of peptide synthesis and is suitable for handling complex preparative purification tasks.

This article discusses several practical examples using bioinert columns, demonstrating their ability to deliver reliable, high-resolution results with precision and reproducibility.
