Specjaliści Restek opracowali kolumnę charakteryzującą się unikalną chemią faz, która łączy w sobie zarówno mechanizmy retencji HILIC jak i jonowymiennej na jednym ligandzie. Ta nowa generacja kolumn chromatograficznych pozwala na łatwiejsze osiąganie separacji pików...

PFAS LC Column Anatomy: Which Phase, Dimensions, and Particle Type Are Best? With the expansion of PFAS target analyte lists into shorter chain compounds, the need for better methods is growing. This article explores the impact of phase, dimensions, and particle type...

Speed Up Analysis of 3-MCPD and Glycidyl Esters in Edible Oils Here, we explore optimization strategies and present improved, indirect GC-MS and GC-MS/MS methods for 3-MCPD and glycidyl esters in edible oils. Using split injection and Pro EZGC software, analysis was...

Split vs. Splitless: Which GC Injection Mode Should I Use? Split and splitless are the two most common GC injection techniques. But how do you know which to use? In this video, we follow a sample through split and splitless injections and compare the strengths of each...
