The headspace grade produced a “cleaner” blank for SH-GC analysis than a lesser grade of DMSO. The peaks that did appear in the headspace grade solvent blank eluted outside of the retention range of the OVIs analyzed. Additional headspace grade solvents (DMF, DMAC, and DMI) suitable for this application are also available.

tatic headspace gas chromatography (GC) is a technique used for the concentra-S tion and analysis of volatile organic compounds. This technique is relatively Time and money are two of the many reasons why an analyst would use static headspace analysis. Other reasons may include ease of operation and the ability to assay a variety of sample

Headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) is an emerging approach in food control that uses new gas-phase separation and detection technology [17,18,19,20]. HS-GC-IMS implements a two-dimensional separation process of volatile compounds, using a combination of GC and IMS, which facilitates the identification and

Headspace-gas chromatography (HS-GC) analysis can be applied successfully for the analysis of VSCs in different liquid matrices. It can be also applied in physical chemistry studies of these compounds, being a valuable tool for acquiring data on gas–solid and gas–liquid systems.
