Solvent-free extraction by passive sampling using TF-SPME and HSSE, and by active pumped sampling onto sorbent tubes, are compared for TD-GC–MS analysis of volatiles.

Olfactory detection of sensory-active compounds guides GC–MS analysis for efficient flavour assessment of foodstuffs and their plant-based replacement products.

Solvent-free extraction and analyte concentration using TF-SPME and SBSE are optimized for TD-GC–MS determination of flavour compounds in hard seltzer beverages.

This study demonstrates the use of pyrolysis-(GC¬–)MS to generate simulated TGA-MS data for polymers. The mode of operation is also referred to as evolved gas analysis.

Smart-ramped pyrolysis-GC¬–MS analysis of microplastics in water filtration residue gives maximum info in one run. Examples are runoff, grey-, pond-, and bottled water.

A micro-scale chamber method performs DNPH derivatization and Tenax TA sorption for analysis of formaldehyde and carbonyl compounds by LC–UV, and VOCs by GC–MS.

Smart ramped pyrolysis-GC–MS analysis of forensic samples such as paint, adhesive tape, and mascara gives maximum info in a single run without method development.
