Majors retired from Agilent Technologies, where he worked in sample preparation and column technology. He is a former LCGC columnist, writing both the “Column Watch” and “Sample Prep Perspectives” columns for LCGC North America for more than 30 years Currently a member of LCGC’s editorial board, Majors has authored more than 150 publications on high performance liquid chromatography (HPLC), gas chromatography (GC), sample preparation, and surface chemistry.
He received his B.S. from California State University, Fresno, and his PhD from Purdue University. His PhD thesis was on molecular-imprinted phases for chromatography and sample preparation. Majors served as Chairman of the HPLC ’86 and Anabiotec ’90 conferences and on the Instrumentation Advisory Board of Analytical Chemistry.
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
Liquid Chromatography to Analyze Vitamin D Proteins in Psoriasis Patients
January 21st 2025Can a protein involved in delivering Vitamin D to target tissues have an altered serum profile in psoriasis patients with cardiovascular disease? Researchers used liquid chromatography (LC) to help find out.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
