Multidimensional and Hyphenated Techniques in Aerosol Analysis
LCGC Europe
The authors provide suggestions for the sample pretreatment and analysis of aerosol particles including the use of on-line SFE–LC–GC–MS, GCXGC and LC–MS. Although each technique has its merits, the novel multidimensional systems and those integrating sample pretreatment with the final analysis proved to be valuable tools in aerosol analysis.
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.
Characterizing Plant Polysaccharides Using Size-Exclusion Chromatography
April 4th 2025With green chemistry becoming more standardized, Leena Pitkänen of Aalto University analyzed how useful size-exclusion chromatography (SEC) and asymmetric flow field-flow fractionation (AF4) could be in characterizing plant polysaccharides.
