Problems solved by technology
[0006] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the current cooling of the column thermostat usually uses a fan to extract the heat in the column thermostat to the outside. The heat dissipation of a group of fans is often limited in efficiency. It usually takes a long time for the temperature of the column oven to drop to the initial temperature, and the cooling efficiency of the column oven is low, which leads to a longer detection time for the next set of samples.

The invention relates to the technical field of detection equipment, and provides a gas chromatograph aiming at the problem that a column oven of a traditional gas chromatograph is low in cooling efficiency, the gas chromatograph comprises a gas chromatograph body, a fan is installed in the column oven of the gas chromatograph body, the column oven of the gas chromatograph body is communicated with an air inlet pipe and an air outlet pipe, the air inlet pipe and the air outlet pipe are both communicated with the outside, the air outlet pipe is opposite to the fan, and the gas chromatograph body is further provided with an opening and closing assembly for closing the air outlet pipe and the air inlet pipe; a water tank for storing cooling water is further arranged outside the gas chromatograph body, a cooling pipe is further arranged in the column oven, the two ends of the cooling pipe are communicated with a water inlet pipe and a water outlet pipe respectively, the water inlet pipe and the water outlet pipe are both communicated with the water tank, and the water inlet pipe is further connected with a main water pump in series. The chromatograph has the effect of improving the cooling efficiency of the column oven.
Description
technical field [0001] The present application relates to the technical field of detection equipment, in particular to a gas chromatograph. Background technique [0002] Gas chromatograph is an instrument for qualitative and quantitative analysis of multi-component complex mixtures by using chromatographic separation technology and detection technology. It can usually be used to analyze various organic substances in daily life to determine their main components. [0003] The gas chromatograph includes a shell, and the shell is provided with components such as a sample injector, a column thermostat, a detector, and a chromatographic column, and a temperature control component for heating and cooling is arranged in the column thermostat. When using a gas chromatograph, first put the chromatographic column into the column thermostat and connect the two ends of the chromatographic column to the injector and detector respectively, put the detection sample into the injector, and ...
