The modular gas chromatograph adopts a large screen display, which realizes Chinese menu style dialogue, making the display clearer and the operation simpler. It can display the lift curve and base flow level, and simultaneously display the temperature set value and actual value of the column box, sampler, detector, etc. in one screen, providing richer and more colorful instrument information. The carrier gas flow monitoring system can be optionally equipped with a new digital flow monitoring unit for the gas path system. It displays the carrier gas flow rate and capillary branch flow rate values on the screen, and can display up to four sets of flow rates. The flow parameters can be automatically stored for easy recording and retrieval of analysis conditions, facilitating flow regulation and calculation of flow ratio. The microcomputer system also has control functions.
Modular gas chromatography can achieve filling column head injection method, suitable for various chromatographic columns; Add a six way valve for gas injection analysis; By using connectors in the packed column sampler, it is easy to perform analysis on a 0.53 wide bore capillary column. The modular gas chromatograph allows for easy disassembly and cleaning of the nozzle and ion collection components. The fixed emitter installation structure ensures high consistency in the performance of each instrument. High resistance rhenium tungsten wire is used, and a thermal conductivity amplification plate is selected. The air insulation structure of * provides higher stability for the TCD.
