Automatic Headspace Sampler AutoHS 128A, 128 Sample Positions (CAT#: STEM-AL-9613-ZJF)

The AutoHS 128A is an automatic headspace sampler for high-throughput gas-chromatography workflows. It uses a dual-flow sample extraction needle together with static-dynamic compensation extraction. The source lists 128 sample positions and 15 heating positions for overlapping sample heating. The standard headspace vial volume is 20 mL. Gas replacement, constant mode, time-progression mode, and multiple-headspace extraction are supported. Repeatability is specified at RSD≤1.5%. The source lists detection capability for 1 ppb benzene in water. A graphical touchscreen interface and remote-control capability support automated sequence operation.
