Features: 1. It can run 1-20 samples automatically without personnel on duty; 2. Power-on self-check, fault alarm and prompt, automatic positioning of sample tray; 3. The sample area, injection valve and sample transfer tube are all individually heated for temperature control; 4. Set the analysis program, press the run button to automatically complete the analysis of all samples; 5. Through time programming, the functions of pressurization, sampling, injection, analysis and backflushing after analysis are automatically realized; 6. Using pressure balance or quantitative loop sampling technology, headspace sampling has narrow peak shape and good repeatability; 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 types of GC injection ports at home and abroad. Technical parameter: Temperature control range of the sample area: room temperature-260℃ in increments of 1℃, heating power about 400W; The temperature control range of the valve sampling system: room temperature—220℃ in increments of 1℃; heating power is about 60W; The temperature control range of the sample transfer pipeline: Room temperature—220°C in increments of 1°C, and the heating power is about 40W; Temperature control accuracy: <±0.1℃; Headspace bottle station: 20 positions; Headspace bottle specifications: 10ml, 20ml (standard) optional; Repeatability: RSD ≤1% (200ppm ethanol in water, N=5); Injection volume control mode: injection time and pressure control injection volume; Injection pressure range: 0～0.4Mpa (continuously adjustable); Backflush cleaning flow: 0～400ml/min (continuously adjustable);
