Thermo Scientific™ 20mm Headspace Vials & Closures. Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your
Headspace vials and closures must form a tight seal for accurate analysis with reproducible results. Available in clear or amber Type I borosilicate glass with crimp or screw thread finishes.
H 2 O Headspace Analysis. For the measurement of water vapor or the total pressure the laser is tuned to a wavelength of 1400 nm on which H 2 0 molecules absorb the laser. Based on the line width of the reading the total pressure inside the sample can be derived. The HSA- H 2 0 system is mainly used for container closure integrity testing of
Headspace vials and closures must form a tight seal for accurate analysis with reproducible results. 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.
by withdrawing a known volume of vial headspace with a gastight glass syringe and injecting manually into a gas chromatograph (GC) for analysis. Headspace samples from vials containing PCE, TCE, CT, TCA, and chloroform were analyzed with a GC-electron capture detector (ECD). Two GC-ECDs were used during the course of the experiments:
Analysis for VC was performed by collecting headspace samples from the effluent sample vials after they had been analyzed with the GC-ECD. Sample vials were allowed to reach equilibrium at 23 °C at least 3 h prior to analysis. A headspace air sample (150 μL) was removed through the septa using a 500 μL gas-tight glass syringe (Hamilton, Reno

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including
