Use of headspace–gas chromatography–ion mobility spectrometry
Apr 16, 2019 · Prior to analysis, samples were melted in an agitated water bath for 15 min at 50 °C and 275 rpm to enable aliquots to be taken. 1 g of CPO sample was weighed into a 20 mL glass headspace vial. Due to high VOC concentration, headspace dilution of pure SPO was conducted, whereby 500 μL of pure SPO headspace was taken and injected into an empty

Determination of Headspace Volatiles in Distilled Spirits
A ratio of 4 mL of sample in a 10 mL vial provided an adequate volume for the headspace to evolve, plus enough physical space for the SPME fiber to be exposed. For the fiber, a 50/30 μm divinylbenzene/Carboxen ® /polydimethylsiloxane coating on a 1 cm long StableFlex™ core was used to maximize the variety of compound types extracted.

Basic Principles of Headspace Analysis | analytics-shop.com
It is important to ensure the correct vial and cap are used! Vial Size: Headspace vials are available in 6, 10 and 20 ml sizes. Use a vial large enough to ensure adequate headspace or phase ratio without excessive dilution of the components of interest. Phase ratio is discussed later and should normally be at least 50 % of the sample volume.
