Design and testing of a new sampler for simplified vacuum

Jul 13, 2016 · The custom-made gas-tight sample container was built from a 20 mL headspace rounded bottom glass vial, further modified to accommodate on the top part two gas-tight ports: one high vacuum glass stopcock and one glass port equipped with a septum for introducing the SPME device.

Development of a headspace-gas chromatography (HS-GC-PID-FID

Nov 01, 2010 · A superficial seawater sample (14.5 mL) for VOC determination was collected from each sampling point directly in the 22 mL glass vials with 0.3 mL formaldehyde (3%) as a matrix modifier and 0.2 mL ethylbenzene-d5 (20 μg L − 1) as a internal standard (IS), then sealed immediately. Samples from the same site were collected in duplicates.

Problems Caused by Moisture in Gas – Chromatographia

Headspace solid-phase microextraction (SPME) Arrow sampling of aqueous samples were proven to be complicated since moisture in the headspace was also sorbed into the SPME sorbent and resulted in distorted or split peaks for the volatile amines. This was the case especially with old used sorbents not so much with the new ones.
