Fully automatic headspace sampler

HS-20AFully automatic headspace sampler

*▲ Comprehensive power on self-test function, automatic positioning of sample tray, automatic alarm for component faults, wiring faults, etc. *▲ Multiple injection modes: single bottle multiple times, single bottle single time, multiple bottles single time. *There are multiple fault diagnosis and handling modes, which can automatically determine the position of the sample bottle and avoid unfilled positions. In the event of a positional malfunction, it can prevent bottle collision. When mechanical motion is abnormal, it can automatically stop and prompt, effectively ensuring the reliability of high-precision motion and avoiding damage. All sample transfer pipelines and quantitative rings use imported high inertia deactivation pipelines, with no residue or cross contamination, ensuring the repeatability and accuracy of sample injection. *The combination of a six way valve and a quantitative loop minimizes dead volume to the greatest extent possible, ensuring injection accuracy. The connection point between the six way valve and the transmission pipeline is located inside the heating insulation box, without any transmission cold points, ensuring the integrity of the sample. ▲ Adopting the classic positive pressure sampling method, it can measure liquid or solid samples with high detection sensitivity. Inject at normal pressure without baseline drift. *All actions are driven by a motor, without the need for external driving gas, making it safe and convenient to use. ▲ Strong compatibility, can be connected to various gas chromatographs at home and abroad, can synchronously start chromatography and workstations, and work together with chromatography. ▲ Six way valves with different operating temperatures can be selected according to customer needs.
