Automatic sample preparation system Centri®

for gas analysisfor SEM

The Centri® platform from Markes International is the first system to offer high-sensitivity unattended sampling and pre-concentration of VOCs and SVOCs in liquid, solid and gaseous samples. Using Markes’ advanced trapping technology, Centri enhances the sensitivity and extends performance of several popular sample introduction techniques for GC–MS: HiSorb™ high-capacity sorptive extraction. Headspace and headspace–trap. Method-compliant thermal desorption. SPME and SPME–trap. A platform for high-throughput, routine, high-sensitivity automated analysis using headspace- and SPME- and SPME Arrow-based workflows, with additional chromatographic performance provided by trap-based preconcentration. Along with advanced options for water management, Centri 90 provides excellent analytical performance across a wide analyte range, and especially for early-eluting VVOCs. Conventional GC injection modes remain available, allowing you to maintain existing workflows while also evaluating the benefits of preconcentration using the focusing trap. The platform is Multi-Gas engable, meaning that you can work with your choice of helium, nitrogen or hydrogen carrier gasses to future-proof your laboratory, cost-saving and further productivity enhancements. Centri 90 has a modular design and is upgradable for thermal desorption and HiSorb, high-capacity sorptive extraction (Centri 180 configuration). Featuring all that Centri 90 offers but with extended capability for thermal desorption (from sorbent tubes) and HiSorb™ high-capacity sorptive extraction, which is provided by a multi-tube autosampler.
