There were many kinds of chemical reagents and chemical products used in the laboratory. During the analysis process, the exhaust gas, which was produced by high temperature evaporation on the sample in gas chromatography or discharged in the liquid chromatography, not only affected the working environment, but also did harm to the analyst's health. Therefore, the importance of health of the laboratory staff could not be ignored.

This year, during the period of production shutdown and overhaul, the company transformed the instrument analysis room of the quality control department and the technical department, added a suction device to the instrument console, and separated the operation room. It not only beautified the working environment, but also guaranteed the air quality in the operating room, so that the health and safety of the analysts could be effectively protected.
