Why use Centri 90?

Flexibility: Fully modular sampling and automation options with a clear upgrade pathway, allowing scientists to comprehensively characterise the VOC and SVOC profiles of solids, liquids and gaseous samples.
Sensitivity: Enhanced chromatographic resolution and greater compound detection through preconcentration and multi-step enrichment (MSE^®).
Automation: A fully automated workflow – including sorptive extraction – using gold-standard robotics to deliver high performance and productivity.
Future-proof: Maximise ROI and reduce reliance on gas cylinders by adopting hydrogen carrier gas now or at a later stage.
Productivity: Centri 90 supports high-throughput analysis of up to 300 sample vials, with a compact footprint for seamless integration with existing GC–MS systems.
Upgrade potential: Centri 90 can be easily upgraded, to Centri 180, to extend the range of techniques by adding thermal desorption capability.
Cost-saving: Eliminate the expense and inconvenience of liquid cryogen, and reduce the risk of ice blockages, by using controlled electrical cooling.

Centri 90 features

HiSorb™ high-capacity sorptive extraction – Robust, fully automated workflows using probe-based immersive or headspace sampling from both liquid and solid samples.
SPME–trap and SPME Arrow–trap– Fast and sensitive sample extraction, with a range of fibre types offering analyte selectivity.
Headspace–trap – Versatile sampling from solids and liquids contained in regular headspace vials.
Multi-Gas enabled – Independently certified as hydrogen safe. Reduce running costs and increase throughput with hydrogen carrier gas.

Who uses Centri 90?

Analysts needing to increase sensitivity of their routine high-capacity sorptive extraction (HiSorb), HS, SPME and SPME Arrow analysis with maximum productivitygains.
Modern chromatographic labs adopting hydrogen carrier gas to preserve natural helium resources, lower cost per run and reducing their dependency from gas cylinders.
Analysts looking to replace time-consuming manual preparation techniques (such as liquid–liquid extraction and SPE) with flexible, automated methods like high-capacity sorptive extraction, thermal desorption, headspace or SPME.
Chemists who routinely quantify VOCs and SVOCs in a single run, benefitting from expertly-tailored multi-sorbent bed traps combined with backflush operation.
Analysts who need flexible, modular, and upgradeable sampling options to analyse solids, liquids and gases using combinations of headspace, HiSorb, thermal desorption (TD), and SPME techniques.
