Introduction: The PT-8000 automatic purge and catch device is the new automatic purge and catch device of Beijing Zhongyi Yusheng Technology Co., Ltd. It can be loaded with 95 sample bottles at a time and can be used with all domestic and imported GC and GCMS. . It is suitable for the analysis of volatile organic compounds in liquids and solids, and can also be used for derivatization reaction treatment of samples. For liquid samples, take a sample to a U-shaped tube for purging; for low-content solid samples, use a 40ml sample bottle to directly purge; for high-content solid samples, automatically extract and dilute with methanol before purging. Types of samples that can be tested: volatile organic compounds in water, wastewater, drinking water, seawater, blood, sediment, mineral mud, soil, cosmetics, textiles, packaging, food, spices, etc. Features: 1. Programmable methanol and warm water cleaning process, effectively reducing sample cross-contamination; 2. Direct purge mode and methanol extraction dilution purge mode can be set for solid samples, and samples of different concentrations can be tested, four kinds of speed can be set to stir and mix; 3. In different modes such as purging, dry blowing and drying, different temperature settings can realize automatic temperature control in each mode; 4. Using electronic flow control, the flow can be automatically adjusted in different modes such as purging, dry blowing and drying; 5. The software completely records sample information and historical information, with detailed and complete data; 6. Power-on self-test, fault alarm and prompt, automatic positioning and calibration of the sample tray; 7. The control software has built-in equipment diagnosis and self-checking functions, which can automatically detect leaks and automatically monitor pressure, and has a diagnostic mode to find leaks; 8. Fully enclosed gas and liquid circuit design to ensure no loss of samples in the pretreatment stage; 9. Foam detector, non-interference detection at 860 nm wavelength, effective detection of gas-liquid interface foam, ensuring real-time detection of foam and timely defoaming during the purge stage; 10. It can realize the automatic dilution of the sample, the dilution factor is 100 times, the sample blank can be automatically configured, and the internal standard solution can be automatically added. 11. The PC software and full-color touch screen are equipped with a micro-industrial control system with operating system, supporting bilingual selection in Chinese and English. 12. The design of the high-efficiency spiral condensation water removal system meets the water removal requirements of the thermal desorption stage of the analysis of polar substances. The water removal efficiency is greater than 97%, and the polar analytes are not affected. 13. The visible sample tube heater ensures constant temperature during purging, improves the recovery rate of the target and the precision of the test results, and makes it safer to use the low-voltage 24V power supply. 14. The trap air-cooled system of semiconductor-assisted refrigeration has a faster cooling rate and a shorter test time. 15. Use LCD touch screen to realize intelligent operation experience. 16. The built-in imported liquid delivery pump and metering pump can control the volume of various solutions added to complete the complex purging, trapping and concentration process. 17. Automatically complete the functions of sample injection, liquid addition, purging, etc., and can realize automatic purging and trapping pretreatment process for various types of liquid and solid samples.
