The volatile organic analysis (VOA) vials are made of borosilicate glass and prepared to meet or exceed EPA standards for volatile organic sampling. Clear or amber glass vials are available in three sizes of 20ml, 40ml, 60ml with standard 24-400 screw neck top.
Available in clear or amber Type I borosilicate glass with crimp or screw thread finishes. The vials are used to heat the sample until the concentration of the liquid and gas phases are in equilibrium. A sample is then taken from the gas phase (headspace) for analysis. 1188P58 and 1188P59: Long neck vials for CTC PAL and PE equipment.

Dec 14, 2007 · In this method, a very small volume (10–20 μL) of liquor sample is introduced into a headspace sample vial (20 mL) and heated up to a temperature of 105 °C. A near-complete mass transfer of methanol from the liquid phase to vapor phase (headspace), i.e., a full evaporation, can be achieved within 3 min. The methanol in the headspace of the
Our chromatography and autosampler vials come in versatile designs for superb performance. The variety of styles and septa materials are available to match your equipment and applications. Headspace vials have round shoulders and bottoms to allow for even heating. We also offer vials to fit instruments that use 1- and 4- mL vials.
Headspace vials have to withstand high internal pressure. Therefore, the wall thickness of headspace vials is higher compared to standard vials for liquid chromatography: 1.2 mm versus 0.9 mm. Headspace vials are available with flat and rounded bottom.
Headspace GC vials. Product Features: Beveled neck headspace vials are avialbale in borosilicate Type I clear & Amber Glass 10 ml & 20 ml volume capacities. For proper fittining to all standard instruments we have both flat bottom & round bottom vials. Headspace vials are available in both crimp cap & screw cap types.
Chromatography of a perfume sample with headspace sampling. Figure 2. Movement of perfume molecules within a sealed and heated vial. much cleaner, easier and faster. A headspace sampling system automates this process by extracting a small volume of the headspace vapor from the vial and transferring it to the GC column.
The dimensions for 12x32mm vials are standard between manufacturers but the length of the neck and width/shape of the vial shoulder may vary. 12x32mm microvials have the same outer dimensions but the inside of the vial may be tapered to reduce volume or contain a fused insert. 12x32mm high recovery vials will have an internal conical bottom
