ZY-6800N atmospheric pre concentration device Introduction: The ZY-6800N atmospheric pre concentration device features automated design, 7-inch capacitive touch screen display, and simple and convenient operation; The ZY-6800N atmospheric preconcentration device can be used in conjunction with all imported and domestically produced GC and GCMS, and can meet the following standards: "HJ 1078-2019 Determination of 8 sulfur-containing organic compounds such as methyl mercaptan in fixed pollution source exhaust gas - Bag sampling - preconcentration/gas chromatography-mass spectrometry", "HJ 759-2015 Determination of volatile organic compounds in ambient air - Tank sampling/gas chromatography-mass spectrometry". Features: 1. Power-on self check, fault alarm and prompt, high-temperature overload protection function, power outage protection function, etc., have increased the safety factor of instrument use. 2. The 7-inch touch screen operation interface design is beautiful, practical, and easy to operate, achieving human-machine interaction process. 3. Three stage cold trap design (electronic refrigeration), excellent ability to remove H2O and CO2, capture temperature up to -196 ℃, and the heating rate of the cold trap can reach 10000 ℃/min. The heating and cooling functions of the cold trap are excellent, allowing for small dose injection, reducing pipeline residue, and ensuring accurate injection accuracy; 4. The preset HJ1078-2019 and HJ759-2015 standard analysis methods can meet the analysis requirements of HJ1078-2019 and HJ759-2015 without any changes during the analysis process; 5. It can automatically add matrix substitutes and internal standards, increasing the analysis of standard gases, achieving the accuracy of analysis results and avoiding sample contamination; 6. High degree of automation, good compatibility, suitable for air bags and suma tanks, and can also be directly connected to automatic samplers. This instrument is equipped with interfaces for various imported instruments, which can connect to GC and GCMS at home and abroad; 7. By using a mass flow meter, flow control in different states can be achieved. No need to manually adjust the flow rate, automatic calculation of gas quality and volume, long service life, low maintenance rate; 8. Equipped with automatic system baking function, avoiding cross contamination of different samples; 9. The instrument operates stably, and the selection of various components considers stability and their service life, reducing the failure rate of the instrument, extending its service life and effective operating time.
