This month's "GC Connections" begins a multipart series about gas chromatograph performance optimization. In this first part, John Hinshaw addresses questions of instrument capabilities and chromatographers' expectations, as well as manual–hardware optimization strategies and software-separation strategies.
LCGC 18(3), 296–306 (2000).Fundamentals of Benchtop GC–MS Data Analysis and Terminology
April 5th 2025In this installment, we will review the fundamental terminology and data analysis principles in benchtop GC–MS. We will compare the three modes of analysis—full scan, extracted ion chromatograms, and selected ion monitoring—and see how each is used for quantitative and quantitative analysis.
Study Examines Impact of Zwitterionic Liquid Structures on Volatile Carboxylic Acid Separation in GC
March 28th 2025Iowa State University researchers evaluated imidazolium-based ZILs with sulfonate and triflimide anions to understand the influence of ZILs’ chemical structures on polar analyte separation.
