      Zy-01 online atmospheric preconcentration unit

      1、 Brief introduction of the instrument

      In order to support the on-line monitoring system of volatile organic compounds in the ambient air and meet the detection limit of VOCs reaching ppb level, the company independently developed and launched zy-01 online atmospheric preconcentration device, which can complete seamless docking with online monitoring systems of various manufacturers.

      2、 Features and main functions of the instrument

      1. Color touch screen, computer program control, main functions are as follows:

      (1) method parameter setting, real-time display of working state and running time;

      (2) the temperature of desorption zone, injection valve, sample transfer tube and secondary desorption zone are all separately heated and controlled;

      (3) loading the applicable analysis program to complete the whole sample processing automatically;

      (4) double cold well components can be added according to the needs of users;

      (5) it is equipped with two interfaces: receiving the output signal interface of the sampling system and sending the starting signal interface;

      2. Electronic refrigeration technology, convenient and practical;

      3. Through time programming, it can automatically realize the functions of adsorption, desorption, low temperature secondary adsorption, desorption, sample injection, back blowing cleaning, etc;

      4. The inert sample transfer tube and injection valve have automatic back blowing function, which can avoid cross contamination of different samples;

      3、 Main technical parameters of the instrument

      1. Desorption 1 temperature control range:

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

      2. Temperature control range of valve injection system:

      From room temperature to 240 ℃, 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. Desorption 2 temperature control range:

      150-400 ℃ in increments of 1 ℃;

      (heating rate > 2000 ℃ / min)

      5. Temperature control range of cold trap:

      -35 ℃~ 50 ℃ in increments of 1 ℃

      (using the most advanced electronic refrigeration device, no need for liquid nitrogen refrigeration)

      6. Temperature control accuracy: < ± 0.1 ℃;

      7. Desorption recovery: > 98% (related to components);

      8. Desorption time: 0.01min-500min;

      9. Sample purging time: 0.01min-500min;

      10. Sample injection time: 0.01min-500min;

      11. Pipeline back blowing time: 0.01min-500min;

      12. Backwash cleaning flow: 0 ~ 100ml / min (continuously adjustable);

      13. Effective size of the instrument: 500 × 482 × 222mm3;

      14. Weight of the instrument: About 20kg.
