        Zy-6800n atmospheric preconcentration unit

        1、 Brief introduction of the instrument

        Zy-6800n atmospheric preconcentration unit is independently developed by Beijing Zhongyi Yusheng Technology Co., Ltd., with automatic design, 7-inch capacitive touch screen display, simple and convenient operation;

        Zy-6800n atmospheric preconcentration device can be used with all imported and domestic GC and GCMs, and can meet the following standards: HJ 1078-2019 determination of 8 sulfur-containing organic compounds in waste gas of fixed pollution source, such as methyl mercaptan in waste gas of fixed pollution source by air bag sampling preconcentration / gas chromatography-mass spectrometry, HJ 759-2015 determination tank sampling / gas chromatography-mass spectrometry for volatile organic compounds in ambient air.

        2、 Features and main functions of the instrument

        1. Power on self-test, fault alarm and prompt, high temperature overload protection function, power-off protection function, etc., which improves the safety factor of the instrument.

        2. Seven inch touch screen operation interface design, beautiful and practical, easy to operate, perfect realization of human-computer interaction process. The main functions are as follows:

        (1) Parameter setting of detection method, real-time display of working state and flow, etc;

        (2) Each channel is heated and controlled by a separate control system, with high control accuracy;

        (3) Set the detection method, press the run key to automatically complete the whole sample analysis;

        (4) It can start the GC and chromatographic data processing workstation synchronously, and can also start the device with external programs;

        3. New national standard, three-stage cold trap design (liquid nitrogen refrigeration), more excellent ability to remove H2O and CO2, capture temperature - 196 ℃, the heating rate of cold trap can reach 10000 ℃ / min. The cold trap has higher heating and cooling efficiency, and can inject small amount of sample, which can reduce pipeline residue and improve injection accuracy;

        4. The standard analytical methods of hj1078-2019 and hj759-2015 are preset, which can meet the analysis requirements of hj1078-2019 and hj759-2015 without any change in the analysis process;

        5. It can automatically add matrix substitute and internal standard, increase the analysis of standard gas, effectively improve the accuracy of analysis results, and better avoid sample pollution;

        6. High degree of automation, good compatibility, suitable for air bag and Suma tank, and can also be directly connected to the automatic sampler. The instrument is equipped with special interfaces for various imported instruments, and can be connected to all types of GC and GCMS at home and abroad;

        7. The imported mass flowmeter and high-precision flow measurement can perfectly realize the flow control in different states. No need to manually adjust the flow rate, automatically calculate the gas mass and volume, long service life and low maintenance rate;

        8. Automatic baking system can avoid cross contamination of different samples;

        9. The instrument runs stably, and the stability and service life of various components are considered in the selection of various components, so as to reduce the failure rate of the instrument and improve the service life and effective operation time.

        3、 Main technical parameters of the instrument

        1. Desorption temperature control range:

        From room temperature to 400 ℃, the increment is 1 ℃;

        (heating rate > 2000 ℃ / min)

        2. Temperature control range of valve injection system:

        From room temperature to 220 ℃, the increment is 1 ℃;

        3. Temperature control range of sample transmission pipeline:

        Room temperature ~ 240 ℃ in increments of 1 ℃

        (low voltage power supply is adopted for temperature control of transmission pipeline for operation safety);

        4. Temperature control accuracy: ± 1 ℃

        5. Three stage cold trap temperature and heating rate:

        Grade I (glass bead cold trap): - 196 ℃ ~ 400 ℃, heating rate > 2000 ℃ / min

        Grade II (Tenax adsorbent cold trap): - 196 ℃ ~ 400 ℃, heating rate > 2000 ℃ / min

        Grade III (cold focusing cold trap): - 196 ℃ ~ 400 ℃, heating rate 10000 ℃ / min

        Note: the instrument has not obtained the medical device registration certificate of the people's Republic of China, and can not be used for clinical diagnosis or treatment
