The vials are covered with polytetrafluoroethylene film, silastic seal, and the aluminum cap is capped by a crimper, sealed, mixed well, and heated in the headspace inlet for 10 min at 60 C. After vapor‐liquid equilibrium procedure specified in Section “Conditions and Operation of GC‐MS,” take 1.0 ml using air‐tight syringe for injection ( n = 3); data are automatically collected by
Headspace gas chromatography–mass spectrometry (HS-GC–MS) is widely considered the gold standard of quantitative fecal VOC analysis. However, guidelines providing general recommendations for bioanalytical method application in research and clinical setting are lacking. To propose an evidence-based research protocol for fecal VOC analysis by HS-GC–MS, based on extensive testing of
