The gas chromatography–mass spectrometry (GC–MS) system is presently routinely used in environmental analysis of trace organic compounds. With the use of a MS-detector, stable isotope-labelled materials’ analogous of the native analyte are convenient internal standard. They can be used for tracing and compensating analytes’ losses during the particular stages of analytical procedure, such as cleaning...
A method for determination of polycyclic aromatic hydrocarbons (PAHs) from aerosols was developed. Instead of conventionally used non-polar or slightly polar phenylmethylpolysiloxane column a highly polar, highly substituted, cyanopropyl column (VF-23 MS) was used for separation of PAHs. Based on hollow fiber micro-porous membrane liquid–liquid extraction (HF-MMLLE) a method was developed for sample...
