ZY-6800N atmospherePre madeConcentrating deviceCan be compatible with all imported and domestic productsGC、GCMSCooperate to makeCan meet the following criteria:《HJ 1078-2019Fixed pollution source exhaust gas Methyl mercaptan, etc8Determination of sulfur-containing organic compounds Air bag sampling-Pre concentration/Gas Chromatography Mass Spectrometry、 《HJ 759-2015 Determination of volatile organic compounds in ambient air - Can sampling/gas chromatography-mass spectrometry method》.
2、 Instrument features and main functions
1. Power on self-test, fault alarm and prompt，high temperatureOverload protection function,Power outage protectionThe functionality has improved the safety factor of instrument use.
2.The seven inch touch screen operation interface design is beautiful and practical, easy to operate, and perfectly realizes the human-computer interaction process.The main functions are:
（1）Parameter settings for detection methods, real-time display of working status, traffic flow, etc；
（2）EachAll roads are controlled by separate control systemsHeating and temperature controlHigh control accuracy；
（3）Set up the detection method,Press the run button to automatically complete the entire sample analysis；
（4）Can start synchronouslyGC、 The chromatographic data processing workstation can also be started with external programs;
3. New national standards,Three stage cold trap design (liquid nitrogen refrigeration) for better removalH2O、exceptCO2Ability to capture temperature-196 ℃, the heating rate of the cold trap can reach 10000 ℃/min. The heating and cooling efficiency of the cold trap is higher, and it can be injected in small doses, which better reduces pipeline residue and improves injection accuracy;
4. PresetsHJ1078-2019、HJ759-2015Standard analysis method, which can meet the requirements without any changes during the analysis processHJ1078-2019、HJ759-2015Analysis requirements;
5. It can automatically add matrix substitutes and internal standards, increase the analysis of standard gases, effectively improve the accuracy of analysis results, and better avoid sample contamination;
6. High degree of automation and good compatibility,Suitable for airbags, Suma cans, and can also be directly connected to an automatic sampler,This instrument is equipped with dedicated interfaces for various imported instruments, which can connect to all models at home and abroadGC、GCMS；
7. Adopting imported quality flow meters for high-precision flow measurement, it can perfectly achieve control of flow in different states. No need to manually adjust the flow rate, automatic calculation of gas mass and volume,Long service life and low maintenance rate；
8Equipped with an automated baking system,Avoiding cross contamination of different samples;
9. The instrument runs stably, and the selection of various components takes into account stability and their service life, in order to reduce the failure rate of the instrument, improve its service life and effective operating time with higher quality.
3、 Main technical parameters of the instrument
