Portable gas chromatography (pGC) is all about tradeoffs. Users demand value, reliability, ease of use, ergonomics, and measurement quality but with analysis limited to gases.
The right chromatography data system (CDS) can spell the difference between a streamlined data collection process and one that is haphazard. CDSs are software packages that collect, store, and help users interpret data.
Manufacturers of high-performance liquid chromatography (HPLC) systems continue to innovate, while simultaneously providing upgrade paths for older instruments.
Among the hyphenated mass spectrometry (MS) techniques, gas chromatography-MS (GC-MS) and high-performance liquid chromatography- MS (LC-MS) are the most notable. These methods combine the resolving power of high-resolution chromatography with the specificity and sensitivity of MS.
