Embodiment Construction
[0014] The continuous gas-liquid phase microextraction device used in conjunction with gas chromatography is composed of a continuous gas liquid phase microextraction device and a sampling device that combines it with gas chromatography. The specific structure of the continuous gas liquid phase microextraction device is as follows: figure 1 , consisting of a liquid phase microextraction syringe 1, a semiconductor condenser, a micro heater, and a gas flow controller 9 connected to an inert gas. The liquid phase microextraction syringe 1 is a 250 μL 020031 hollow push rod syringe, and the extraction syringe 1 is placed on a plexiglass stand 2. Inside, it is connected with the semiconductor cooling sheet 3 of the semiconductor condenser on the lower right side. One end is connected with the aluminum sheet 13, and the other end of the aluminum sheet 13 is connected with the heat sink 15 and the fan 14, so as to achieve the effect of rapid cooling. The extraction syringe 1 is conne...
