Problems solved by technology

[0003] The current mining gas chromatograph takes 2 hours to stabilize the start-up and cool down when the power is turned off. During this period of time, the laboratory analysts cannot perform the laboratory analysis of normal gases. According to the normal 8-hour working system, the laboratory analysis work can only be performed every day. Being able to work for 4 hours is not conducive to improving work efficiency; and the number of gas bladders in the mine is large, which often causes laboratory analysts to work overtime, causing great inconvenience and distress to laboratory analysts and management personnel
