A method for the quantitative determination of dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), bis(2-ethylhexyl) adipate (DEHA), bis(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP), dioctyl terephthalate (DOTP), diisononyl phthalate (DINP), and diisodecyl phthalate (DIDP) in medical infusion sets was developed and validated using gas chromatography coupled with triple quadrup...

Comprehensive gas chromatography-mass spectrometry (GC×GC-MS) provides a different perspective in metabolomics profiling of samples. However, algorithms for GC×GC-MS data processing are needed in order to automatically process the data and extract the purest information about the compounds appearing in complex biological samples. This study shows the capability of independent component analysis...

A gas chromatograph (GC) coupled with a mass spectrometer (MS) forms a powerful tool for high quality quantitative and qualitative analysis. However, GC/MS analysis of complex mixtures such as essential oils often is a time-consuming task due to limitations in techniques and instrumentation. Faster analyses of these mixtures are possible by coupling the 5973A mass selective detector (MSD) with ...

In this study, star anise (Illicium verum) essential oils (SAEOs) were extracted by hydrodistillation (HD), ethanol solvent extraction (ESE), supercritical CO2 (SCD) and subcritical (SE) via electronic nose (E-nose), gas chromatography-mass spectrometry (GC-MS), GC-ion mobility (GC-IMS). GC-MS GC-IMS used to identify the volatile compounds, was also determine their concentrations. Principal com...
