网页Headspace vials are common for analysis of volatile organic compounds, such as blood alcohol content, pharmaceuticals, and food flavoring analysis. The analytes of interest can be isolated in the gaseous phase, so the gas from the headspace portion of the sample vial is injected onto the GC column. For this reason, a larger vial is required

网页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.

网页2007年4月5日 · Or you might need to add salt to your sample to increase the "evaporation" of your analytes in the vials during the thermostating or equilibration of the vials. Remember that phase ratio (volume of gas phase/volume of liquid phase) is very important when running HS analyses. Best regards. Peter Apps. Posts: 5272. Joined: Thu Oct 13, 2005

网页Introduction. Headspace analysis is a technique for sampling and examining the volatiles associated with a solid or liquid sample. The actual headspace itself is the volume of vapor or gas above the sample. For most headspace analysis purposes the sample and its associated headspace are held within an enclosed container (Figure 1 ).
