Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer (Figure 1).

Oct 25, 2021 · Make sure this fits by entering your model number. 6ml vial Size: 22*38mm, the vial mouth outer diameter is 20mm,20 mm crimp seal finish are designed to fit most headspace autosamplers. Beveled Finish Vial : Reduced the amount of sealing surface between the crimp seal and the glass surface,Also A bevelled top Headspace Neck might be required for some special closure systems (PerkinElmer)

Chromatography Septa Components on top of the injection port of GC systems that provide a leak-free seal between the atmosphere and carrier gas and minimize the introduction of contaminants; allow repeated sample injection without significant coring or leaking. 1 – 30 of 43 results 1 Thermo Scientific™ Septa A wide range to cover most applications

A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance. PTFE provides increased chemical resistance.

All of our headspace vials have a greater wall thickness and round base which enables them to withstand pressure up to 60 psig. Low-volume sampling can be achieved by using a 6 mL vial and vial adapter. All PerkinElmer headspace vials are manufactured to specific tolerances that are guaranteed for fit and performance.

11mm crimp top vials are uniformly flat bottom for security with insert . Wide opening vial is easier to fill and provides a larger target area for the austosampler needle. Standard Autosampler Vial for HPLC & GC Chromatography, vials can be used for high performance liquid chromatography and gas chromatography for reliable analysis results.
