Metabolic profiling of breath analysis involves processing, alignment, scaling and clustering of thousands of features ex-tracted from Gas Chromatography Mass spectrometry (GC-MS) data from hundreds of participants.
For mass spectrometry (MS)-based metabolomics it is recommended to include the analysis of reference samples (preferably pooled study samples), as an added quality control (QC) measure at regular intervals throughout an analytical sequence.
Advances in Mass Spectrometry and MS data processing are enabling the analysis of micro samples and unknown components that were not previously observed. As the volume of information acquired from MS instruments increases, researchers are calling for more simple techniques to analyse the numerous components observed.

Forensic laboratories routinely analyze samples collected from fire scenes for the presence of ignitable liquid residues (ILRs). ILRs are often recovered from fire debris using a passive heated headspace extraction, with adsorption of volatile components on active carbon followed by solvent or thermal desorption.
