PT-7900D-ⅡType fully automatic blowing and capturing device
Instrument Introduction
PT-7900D-Type II blowing and capturingIt is a new generation fully automatic water and soil integrated blowing and capturing device independently developed by Beijing Zhongyi Yusheng Technology Co., Ltd. Adopting a seven inch touch screen display control, imported injection pump sampling, electronic cold trap using imported semiconductor refrigeration capture, imported switching valve injection,MFCElectronic flow control, can be loaded at full load once72 sample bottles, compatible with all domestic and imported GC and GCMS.
functional configuration
1. Can automatically run at full load72 samples, no need for personnel on duty;
2. The functions of account login, system self-test, fault alarm and prompt, temperature overload protection, leakage protection, etc. have improved the safety factor of instrument use;
3. All gas paths are treated with inertness, using imported electric switching valvesMFCMass flow controllerhigh-precisionelectron pressuresensingThe device,approveControl the carrier gas pressure and purge flow rate to achieve stable retention time;
4. Parameter settings for detection methods, real-time cloud display of working status, running time, traffic flow, etc.
5. Program controlled sample area, injection valve, sample transfer tubeCold trapSix temperature channels in the desorption zone of the water trap and capture tube, with a temperature rise rate of up to1800℃/min；
6. The seven inch touch screen operation interface design is beautiful, practical, easy to operate, and perfectly realizes the human-computer interaction process;
7. Can start synchronouslyGCAnd workstationsAlternatively, it is also possibleImplementation andCounter control between GCs;
8. A brand new software control system that automatically performs functions such as blowing, trapping, desorption, injection, and backwashing with just one click;
9. This device is equipped with automatic sample mixing function；UOptional Type Purging Tube5ml、25ml；
10. The automatic blowback function of the entire blowing and injection system can effectively avoid cross contamination of different samples;
11. A water trap is equipped in front of the capture trap to reduce the impact of water vaporThe impact of GCMS.
12. This instrument is equipped with dedicated interfaces for various imported instruments,Can connect all models both domestically and internationallyGC、GCMS；
13. Added log, help, stopwatch, and Chinese English interface switching functions to provide more convenience.
Application scope
