Automated sample preparation platform for GC–MS Analysis of VOCs /SVOCs in solids, liquids and gases, to be launched at Pittcon 2023

Mar 17 2023

Markes International  is launching the Centri 90, the latest addition to its award-winning automated sample preparation platform, Centri®, at Pittcon 2023. The company will be unveiling the Centri 90 on its Booth #2519.

The Centri 90 is an entry-level, modular, automated sample preparation, extraction, and concentration platform for the GC–MS analysis of VOCs /SVOCs in solids, liquids, and gases. It delivers outstanding sensitivity and enhanced productivity for routine headspace, SPME, and SPME Arrow applications. Markes’ proprietary cryogen-free trapping technology maximizes the sensitivity of these techniques and makes Markes’ product unique. The Centri 90 platform can be upgraded, at any time, to add thermal desorption and high-capacity sorptive extraction capabilities.

“The new Centri 90 is a breakthrough in automated sample preparation, extraction, and concentration for routine GC–MS analysis. It integrates seamlessly with all major brands of GC, and it is easy to upgrade existing robotics and bring new life to GC–MS workflows, to obtain superior-quality data and help analysts make better-informed decisions, while retaining automated sample preparation and GC injection," said Massimo Santoro, Director of Business Development at Markes International.

The Centri 90 ensures data-confidence through its automated system leak checks and innovative diagnostics and has an automated gas-phase internal standard addition, a requirement for compliance with some standard methods.

“We’re very excited to be launching the Centri 90 at Pittcon, and to see analysts’ reactions to it. We believe that its key applications lie in food safety testing for residual fumigants in seeds and spices, olive oil authenticity testing, and monitoring VOCs in environmental air, water, and soil. That said, we’ll be keen to hear of other potential applications from Pittcon delegates," said Rachael Szafnauer, Markes’ Marketing Manager for its sample preparation range of instruments.

Markes’ award-winning Multi-Gas technology is in-built in Centri 90, enabling the instrument to be used with either helium, nitrogen, or hydrogen as carrier gases. It’s been independently certified for safe use with hydrogen, which delivers faster chromatographic speeds, and lowers the cost-of-ownership and maximizing return-on-investment.
