Markes International’s Centri, a fully automated multi-mode sampling and concentration platform for GCMS, uses robotics to reliably automate sampling and pre-concentration of volatile and semi-volatile organic compounds (VOCs and SVOCs) through the following sample introduction modes—HiSorb high-capacity sorptive extraction, headspace, headspace-trap, SPME, SPME-trap and thermal desorption.
Analyte flows from all modes can then be concentrated on a sorbent-packed cryogen-free focusing trap. A principal feature of the platform is that it automates the entire process of sampling, pre-concentration and GC injection for solids, liquids and vapors—this allows major productivity improvements to be made. Another popular feature is the ability to automate high-capa...
