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

Basic Principles of Headspace Analysis | analytics

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.

Headspace Solid-Phase Microextraction Gas

A headspace solid-phase microextraction (HS-SPME) and gas chromatography−selective ion monitoring/mass spectrometry (GC−SIM/MS) method was optimized for analysis of 22 volatile compounds in orujo spirit samples from the Geographic Denomination “Orujo de Galicia/Augardente de Galicia”. HS-SPME experimental conditions, such as fiber coating, extraction temperature,
