AHS-20A automatic head air compressor Introduction
The AHS-20A fully automatic headspace sampler is a new gas chromatograph sample preparation device that is low-cost, high-performance and widely used in our company. It can quickly and accurately extract volatile compounds from any matrix. And completely transferred to the gas chromatograph. The instrument adopts a 7.0-inch graphic dot-matrix liquid crystal display, which is user-friendly, clear and concise; the animation display and setting based on the injection principle can be started without the need for too much effort, which is convenient for the user to operate quickly. Features
1.All Chinese 7 inch LCD display, easy to operate, one button to start. The functions of automatic heating, balancing, pressurization, sampling, injection, analysis and analysis of the purge, and the replacement of the sample vials are fully automated.
2.20 samples can be preset, which greatly improves the time utilization. No manual intervention is required, which improves the reliability and consistency of the analysis.
3.has complete parameter settings, real-time working status, running time, year, month and day.
4.Comprehensive power-on self-test function, automatic alarm of sample tray automatic positioning, component failure, wiring failure, etc.
5.A variety of injection modes: single bottle multiple times, single bottle single time, multiple bottles single time.
6.There are a variety of fault diagnosis processing modes, which can automatically determine the position of the sample vial and automatically avoid the unfilled position. In the event of a positional failure, it is possible to avoid hitting the bottle. When the mechanical movement is abnormal, it can automatically stop and prompt, effectively ensuring the reliability of high-precision motion and avoiding damage.
7.All sample transfer lines and loops are imported with high inert deactivation lines, no residue, no cross-contamination, to ensure the repeatability and accuracy of sample injection.
8.The combination of the six-way valve and the quantitative ring minimizes the dead volume and ensures the injection accuracy.
9.The connection point between the six-way valve and the transmission line is in the heating incubator, and there is no transmission cold spot to ensure the integrity of the sample.
10.The classic positive pressure sampling method can be used to measure liquid or solid samples with high detection sensitivity. Atmospheric pressure injection, the baseline does not drift.
11.All actions are driven by motor, no external driving gas is required, and it is safe and convenient to use.
12.It has strong compatibility and can be connected with various gas chromatographs at home and abroad. It can simultaneously start chromatography and workstation, and work with chromatography.
13.According to customer needs, six-way valves with different working temperatures and imported inert syringes can be selected.
14.EPC electronic flow control is used to improve instrument reliability (optional). Technical Parameters
