Concentration analysis of volatile components using a sample concentration needle.
GC/MS: Gas Chromatography-Mass Spectrometry
The sample concentration needle is a device that concentrates volatile components by sucking them from vials or sampling bags and adsorbing the volatile components passing through the needle onto an adsorbent medium, which is then introduced into GC/MS. There are different adsorbent media available, such as "for organic solvents," "for fatty acids," and "for amines," which are used depending on the target components. In the headspace method used for the analysis of volatile components, it is common to heat the sample to obtain sensitivity; however, in analyses using the sample concentration needle, heating is not necessary, allowing only the volatile components to be supplied for GC/MS analysis at room temperature.
