Automatic Headspace Sampler AutoHS 40A, 40 Sample Positions (CAT#: STEM-AL-9615-ZJF)

The AutoHS 40A is an automatic headspace sampler with multiple operating modes for gas chromatography. It provides 40 sample positions and 15 heating positions. The sampler uses static-dynamic compensation injection with 20 mL headspace vials. Gas replacement, constant mode, time-progression mode, and multiple-headspace extraction are supported. The source states that full-flow-path automatic leak testing is available. Electronic pressure control is included in the listed feature set. Repeatability is specified at RSD≤1.5%, with a listed detection capability of 1 ppb benzene in water. A color touchscreen and remote-control functions support stored and automated analytical sequences.
