The PFA headspace injection bottle, as a high-purity sample vessel for gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS), plays a crucial role in precise analysis due to its excellent chemical inertness, low adsorption, and high temperature resistance. Application in high-precision analysis: -Detection of toxic and harmful gases and volatile organic compounds in environmental monitoring; -Inspection of residual solvents in food packaging materials in food safety; -Determination of solvent residues in raw materials and finished drugs in drug analysis; -Accurate measurement of light and trace components in petrochemical products. #Injectionbottle #PFAVessel #Environmentaltesting #Highprecisionanalysis #Foodtesting #Chemicalpharmaceuticals #Traceanalysis
