APL-HS-120 fully automatic headspace sampler Introduction: The APL-HS-120 fully automatic headspace sampler can achieve full automation of sample heating balance, injection, automatic start of chromatographic analysis, cleaning, and other processes, ensuring chromatographic analysis accuracy and improving chromatographic analysis efficiency! Features: 1. Can automatically run 1-120 samples without the need for personnel on duty; 2. Power on self check, fault alarm and prompt, sample tray automatic positioning; 3. The sample area, injection valve, and sample transfer tube are all individually heated and temperature controlled; 4. Set up the analysis program and press the run button to automatically complete all sample analysis; 5. Through time programming, automatic functions such as pressurization, sampling, injection, analysis, and backwash cleaning after analysis are achieved; 6. The use of pressure balanced injection technology or quantitative loop injection is optional; 7. The sample transfer tube and injection valve have automatic backflushing function to avoid cross contamination of different samples; 8. The injection needle is easy to replace and can be connected to all models of GC injection ports both domestically and internationally. Technical parameters: The temperature control range of the sample area: room temperature -280 ℃, set in increments of 1 ℃, with a heating power of approximately 400W; The temperature control range of the valve injection system: room temperature -280 ℃, set in increments of 1 ℃, with a heating power of approximately 60W; The temperature control range of the sample transmission pipeline: room temperature -280 ℃, set in increments of 1 ℃, with a heating power of about 40W; Temperature control accuracy:<± 0.1 ℃; Head space bottle station: 120 positions (15 heating stations); Headspace bottle specifications: 10ml, 20ml (standard) optional; Repeatability: RSD ≤ 1% (ethanol in 200ppm water, N=5); Injection volume control mode: Injection time and pressure control injection volume; Injection pressure range: 0-0.4Mpa (continuously adjustable); Blowback cleaning flow rate: 0-400ml/min (continuously adjustable);
