In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
The Next Frontier for Mass Spec: Maximizing Ion Utilization
January 20th 2025MOBILion has introduced a new high-resolution mass spectrometry (HRMS) approach that can increase speed and sensitivity in omics applications. The parallel accumulation with mobility aligned fragmentation (PAMAF) approach substantially increases the fraction of ions used for MS analysis by replacing the functionality of the quadrupole with high-resolution ion mobility.
