Sansom, Catherine E.;Perry, Nigel B. published 《Analytical artefacts: H2 carrier gas hydrogenation of plant volatiles during headspace solid-phase microextraction gas chromatography》. The research results were published in《Phytochemical Analysis》 in 2022.Formula: C10H22O The article conveys some information:
Hydrogen is the most efficient and economical carrier gas for gas chromatog. (GC). However, there are rare reports of artifact formation by hydrogenation of unsaturated compounds on GC. Head space solid-phase microextraction (HS-SPME) GC conditions for hydrogenation were studied. HS-SPME-GC-mass spectrometry (MS) analyses of common classes of plant volatiles were carried out using hydrogen (H2) and helium (He) carrier gases with different SPME fiber coatings, GC inlet temperatures, and desorption times. Common phenylpropanoids, monoterpenes, and green leaf volatiles were hydrogenated to varying degrees on HS-SPME-GC with H2 carrier gas and SPME fibers coated with polydimethylsiloxane (PDMS)/Carboxen (CAR), PDMS/divinylbenzene (DVB), and PDMS/CAR/DVB. No artifacts were detected using PDMS-only coated fibers or He carrier gas. Unsaturated plant volatiles may be hydrogenated on HS-SPME-GC when using H2 carrier gas with SPME fiber coatings containing DVB polymer or CAR porous particles. Parallel analyses with He and H2 carrier gases are recommended when developing HS-SPME-GC methods for plant volatiles, or use of PDMS-only coated fibers. The experimental procedure involved many compounds, such as 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .
3,7-Dimethyloctan-3-ol(cas:78-69-3) is a fatty alcohol that is 3-octanol substituted by methyl groups at positions 3 and 7.Formula: C10H22O Metabolite observed in cancer metabolism. It has a role as a human metabolite.
