One: Self-diagnostic control system: 1) core test; 2) automatic test; 3) extended test; 4) basic test; it can continuously check the working status of the instrument, and allow the operator to maintain the instrument by himself according to the fault information. Two: Protection function: 1) Over temperature protection; 2) Probe open or short circuit prompt; 3) TCD hot wire protection; 4) FID flameout prompt; 5) FPD light leakage protection; 6) One: Self-diagnosis control system: 1) Core Test; 2) Automatic test; 3) Extended test; 4) Basic test; It can continuously check the working status of the instrument, and allow the operator to maintain the instrument by himself according to the fault information. Two: protection function: 1) over temperature protection; 2) probe open or short circuit prompt; 3) TCD hot wire protection; 4) FID flameout prompt; 5) FPD light leakage protection; 6) password lock keyboard and other functions, multiple protection functions It can guarantee the long-term normal operation of the instrument. Easy operation and high degree of automation: 1) Input various parameters in the form of man-machine dialogue, with prompt function; 2) Four analysis methods can be stored, and the methods can be automatically linked; 3) Autosampler can be connected; 4) Method is running Various parameters can be changed at any time; 5) The method can automatically cycle up to 99 times, which is especially suitable for the normal operation of the instrument without guarding. Three: A variety of sample injection units are available: 1) packed column head sampler; 2) packed column fast vaporization sampler; 3) automatic and manual gas sampling valve; 4) headspace sampler; 5) thermal Desorption sampler; 6) Capillary split/splitless sampler, three samplers or two capillary split/splitless samplers can be installed at the same time to realize a dual capillary system. Four: A variety of detectors are available: 1) Thermal conductivity detector; 2) Hydrogen flame ionization detector; 3) Electron capture detector; 4) Flame photometric detector; 5) Thermionic detector, which can be installed at most at the same time 2 thermal conductivity detectors or three different detectors. Optional methanator: 1) Built-in type; 2) External type. Five: Amplifier time programming: each detector amplifier has a 5-stage time programming function, which can automatically change the attenuation, range and polarity of the output signal. External event time programming: Four external events have a 20-step time programming function. The meteorological chromatograph can complete the automatic control of three automatic injection valves, switching valves and backflush valves; the meteorological chromatograph can perform two detectors Signal conversion
