When the highest levels of throughput are critical to your operations, choose the Clarus 690 gas chromatograph. Its patented high-performance oven delivers the fastest heat-up and cool-down of any oven in the business, and that means shorter injection-to-injection times, and the ability to run more samples per day. Plus, the oven's twin-wall design with concentric air exhaust provides exceptional cooling to near-ambient temperatures without resorting to liquid cryogen – critical for analysis of VOCs. The Clarus 690 GC features a wide-range flame ionization detector (FID), a new high-performance capillary injector with decreased reactivity, and autosampler technology that delivers multiple options for liquid injection, headspace, and SPME on one system.
