A simple high-throughput headspace gas chromatographic

Dec 20, 2020· The vial was placed in the headspace sampler tray for the automatic HS-GC measurement. The method was calibrated using the oxygen in air (20.9%) enclosed in a reference vial filled with 18 mL of glycerol. The vapor phase in the vial was measured by HS-GC under the same conditions as those used with the water sample. 3. Results and discussion 3.1.

Headspace & SPME Vials Vials | gas chromatography vials supplier-gc vials online

Headspace vials are available in several sizes (5-27 mL) and styles in clear or aer glass. The most common sizes are 6, 10 and 20 mL. The style and diameter of headspace vials will depend upon your autosampler. The top finish of the vial can be a flat top or beveled finish. Using a beveled finish vial reduced the amount of sealing surface between the crimp seal and the glass surface.

How to clean the residual pollutants in the headspace sampler?

In the blank test (headspace pure water), more impurity peaks were found. First, measure the temperature of the program temperature (do not use headspace injection, directly start the chromatographic data acquisition. Determine the fault loion in the GC or HS), and find that the program temperature blank is normal, there is no peak interference.
