Rapid, Automated, and Accurate Determination of Volatiles in Human Blood by Headspace Gas ChromatographyInstrument Type: GC
The purpose of this application is to describe the determination of blood alcohol levels by using the Trace 1310 GC in dual-column configuration, coupled with the new Triplus 300 Headspace Autosampler. Blood alchol content analysis is one of the most common test in forensic science and it is generally performed via headspace gas chromatography with flame ionization detection (FID). The use of Chromeleon CDS software is employed to easily perform the analysis in the dual-column / dual-FID configuration in a fully automated manner.
Simple isocratic separation of acetaldehyde, lactic acid and acetic acid using a mixed-mode HPLC columnInstrument Type: HPLC
In this work, the separation of acetaldehyde, lactic acid and acetic acid was achieved using the Thermo Scientific Acclaim Mixed-Mode WAX-1 column. This column allows control over two retention mechanisms, leading to the development of a simple isocratic separation method.
Concentration of patulin and hydroxymethylfurfural in apple juice using in-line SPEInstrument Type: HPLC
Patulin and hydroxymethylfurfural (HMF) are both weakly hydrophobic, neutral compounds, and co-elute on many reversed-phase columns. Fruit juice is a complex matrix, so some form of sample cleanup is necessary. In this work, in-line solid phase extraction is performed. The Thermo Scientific Acclaim Mixed-Mode WCX-1 permits organic acids and phenolics to wash out by ion exclusion well ahead of the HMF and patulin (which co-elute on this column). The auxiliary valve transfers the analytes to the Acclaim C30 column that provides excellent resolution of these two substances.
