    PT-7900D- automatic purge and catch device
    Introduction:
     PT-7900D- purge and capture device is a new generation of automatic water and soil integrated purge and capture device developed by Beijing Zhongyi Yusheng Technology Co., Ltd. Application range: The detection concentration of volatile organic compounds in the detection environment can reach ppb level; it is mainly used for the analysis of volatile organic compounds in water and soil, and can also be used for the analysis of volatile compounds in food.
    Features:
    1. 72 samples can be run automatically without personnel on duty;
    2. The boot system self-check, fault alarm and prompt function, temperature overload protection function, leakage protection function, etc., improve the safety factor of the use of the instrument;
    3. The gas path uses inertly treated stainless steel pipes and PEEK pipes, and adopts imported electric switching valves and imported electronic pressure sensors, which can display the carrier gas pressure in real time and achieve stable retention time;
    4. Parameter setting of detection method, real-time cloud image display of working status, running time, flow, etc.;
    5. The program controls the seven-channel temperature of the sample zone, injection valve, purge tube, sample transfer tube, cold trap, dewatering trap, and trap tube desorption zone, and the temperature rise rate of the desorption temperature can reach 2000/min;
    6. Seven-inch touch screen operation interface design, beautiful and practical, easy to operate, and can smoothly realize the human-computer interaction process;
    7. Automatic liquid filling function of the syringe pump;
    8. It can start GC and workstation synchronously, and can also realize anti-control with GC;
    9. Brand-new software control system, one-key automatic execution of functions such as purging, trapping, desorption, sample injection, backflushing and cleaning;
    10. Methanol cleaning and high-temperature water cleaning technologies effectively reduce cross-contamination and residual problems during the analysis of high-concentration liquids or solids;
    11. Adopt MFC mass flow controller, which can automatically adjust the sample flow rate and control the sample volume;
    12. This device has automatic sample stirring function; U-shaped purge tube can be 5ml or 25ml;
    13. The automatic back-flushing function of the entire purge and sampling system can effectively avoid cross-contamination of different samples;
    14. Equipped with a water removal trap before the trap to reduce the influence of water vapor on GC\GCMS;
    15. This instrument is equipped with interfaces for various imported instruments, which can be connected to all types of GC and GCMS at home and abroad;
    16. Add log, help, stopwatch, and provide more convenience.
    Technical parameter:
    Dewatering trap temperature control range: from room temperature to 240°C in increments of 1°C, and the heating power is about 100W;
    The temperature control range of the valve sampling system: room temperature—220°C in increments of 1°C, and the heating power is about 150W;
    The temperature control range of the sample transfer pipeline: from room temperature to 220°C with an increment of 1°C, and the heating power is about 200W;
      (For operational safety, low-voltage power supply is used for temperature control of the transmission pipeline)
    The control range of the trapping tube desorption temperature: from room temperature to 400 in increments of 1; (heating rate>2000/min)
    Cold trap temperature: the refrigeration temperature can reach minus 30 degrees, using electronic refrigeration devices;
    Sample temperature control range: from room temperature to 90 in increments of 1, the heating power is about 250W;
    Accuracy control range of hot water pool: room temperature—90 in increments of 1, heating power about 220W
     The temperature control range of the purge tube: room temperature—90, can be set in increments of 1, heating power is about 50W
     Temperature control accuracy: ±0.1; temperature control gradient: ±1; 72 sample bottle stations;
    Sample bottle specification: 40ml;
    Purge flow: 0100ml/min (continuously adjustable);
    Backflush flow rate: 0200ml/min (continuously adjustable);
    The effective size of the instrument: 870×500×570mm3;
    17. The weight of the instrument: about 38kg.
