Centri – NEW multi-mode sample automation & concentration platform for GC–MS

Building on 20 years of excellence and leadership in the analysis of trace organic chemicals, Markes International has introduced Centri® – a breakthrough in sample automation and concentration for GC–MS.

Centri is a multi-mode platform that combines market-leading robotics and cryogen-free analyte-trapping technologies to reliably automate sampling, pre-concentration and injection of VOCs and SVOCs, giving enhanced throughput and performance for several popular sample introduction modes:

  • HiSorb™ high-capacity sorptive extraction – Robust probe-based immersive or headspace sampling from liquids and solids.
  • Headspace and Headspace–trap – Versatile sampling from solids and liquids contained in regular headspace vials.
  • SPME and SPME–trap – Fast and sensitive sample extraction, with a range of fibre types offering analyte selectivity.
  • Thermal desorption – Using tubes packed with sorbent for sampling of low-concentration VOCs and SVOCs, or for direct desorption of small samples.

Analyte flows from all sampling modes can be concentrated on a sorbent-packed, cryogen-free focusing trap, which greatly enhances sensitivity and allows selective purging of interferents such as water and solvents.

In all modes, samples can be split and re-collected onto a clean sorbent tube, which offers numerous benefits, including greater sample security and the ability to carry out repeat analyses of a single sample.
