Jul 16, 2018 · The level of short-chain fatty acids (SCFAs) is related to health benefits. In this study, a static headspace (HS) gas chromatography method was developed and validated for analyzing SCFAs in fecal samples. SCFAs were injected onto a column through an HS injector through an HS procedure and salting-out technology. The limits of detection and quantification (LOQ) of this method are 0.02–0.08

The system can handle standard headspace apps (that require temperatures lower than 150°C) while still being well-suited to special high-temperature apps that include analysis of high-boiling compounds and polymers. HT2000HT is the perfect instrument for quality control of chemical product materials and for heat-induced degradation studies.
