Introduction: AHS-20A Plus automatic headspace sampler is a new type of low-cost, excellent performance, and widely used new gas chromatograph sample pretreatment equipment launched by our company. It can quickly and accurately extract the volatiles in any matrix The compound is completely transferred to the gas chromatograph. The instrument uses a 7.0-inch graphic dot matrix LCD display, with a friendly interface, clear and concise; the animation display and settings based on the principle of sample introduction can be used without too much effort, which is convenient for users to quickly operate. Features: 1. 20 samples can be preset, which greatly improves time utilization. No manual intervention is required, which improves the reliability and consistency of the analysis. 2. It has complete parameter settings, real-time working status, running time, year, month, day, etc. 3. Comprehensive power-on self-check function, automatic sample tray positioning, component failure, wiring failure and other automatic alarms. 4. Multiple sampling modes: single bottle multiple times, single bottle single time, multiple bottles single time. 5. There are multiple fault judgment processing modes, which can automatically judge the position of the sample bottle and automatically avoid the unfilled position. In the event of position failure, it can avoid bottle collision. When the mechanical movement is abnormal, it can automatically stop and prompt, which effectively guarantees the reliability of high-precision movement and avoids damage. 6. All sample transfer pipelines and quantitative loops are imported high-inert deactivation pipelines, no residue, no cross-contamination, to ensure the repeatability and accuracy of sample injection. 7. The combination of six-port valve and quantitative ring reduces the dead volume and ensures the accuracy of injection. 8. The connection point between the six-way valve and the transfer pipeline is in the heating and incubator, and there is no transfer cold spot, which ensures the integrity of the sample. 9. The classic positive pressure sampling method can measure liquid or solid samples with high detection sensitivity. Normal pressure injection, the baseline does not drift. 10. All actions are driven by motor, no external driving gas is required, safe and convenient to use. 11. Strong compatibility, can be connected with various gas chromatography at home and abroad, can start the chromatography and workstation simultaneously, and work together with the chromatography. 12. According to customer needs, six-way valves with different working temperatures and imported inert injection needles can be selected. 13. Use EPC electronic flow control to improve instrument reliability (optional). technical parameter: Sample heating range: 40℃—220℃, temperature control accuracy 1℃ (According to customer requirements, the configuration can reach 300 ℃) .Sampling valve heating range: 40℃—220℃, temperature control accuracy 1℃ (According to customer requirements, configuration configuration can reach 300 ℃) Heating range of sample transfer tube: 40℃—220℃, temperature control accuracy 1℃ (According to customer requirements, configuration configuration can reach 300 ℃) Temperature accuracy: 0.5% Temperature stability: <±0.5℃ Pressure time: 0—999S Sampling time: 0-30min Injection time: 0—999S Cleaning time: 0-30min Time interval setting: 1mS (0.001S) Pressurizing pressure: 0~0.25Mpa (continuously adjustable) Volume of quantitative tube: 1ml (other specifications can be customized, such as 0.5ml, 2ml, 5ml, etc.) Headspace bottle specifications: 10ml or 20ml (other specifications can be customized, such as 50ml, 100ml, etc.) Sample station: 20 Samples can be heated at the same time: 1 person RSD: <1.0% (100ppm ethanol aqueous solution) Backwash cleaning flow: 0～100ml/min (continuously adjustable) Synchronously start the chromatographic data processing workstation, GC or external events to start the device synchronously Computer USB communication interface, all parameters can be set by the computer, can also be set by the panel, convenient and quick
