Laboratory as a department with many precision instruments, the daily maintenance of its instruments is very important.

Precision instrument analysis is divided into High Performance Liquid Chromatography and Gas Chromatography analysis. As QC requires strong theoretical and practical ability, testing personnel need to continuously improve their skill level. These positions in QC require strong theoretical and practical operation ability, also require inspectors to continuously improve their skill.

In the case that the precision instrument group needs to constantly learn and skillfully complete the detection work, it is also necessary for the inspectors to Ｍaster some maintenance and maintenance skills. To handle the replacement of high performance liquid phase parts and troubleshooting like simple problems- pressure fluctuations, baseline drift and gas chromatograph column plugging, inlet and detector cleaning, to effectively ensure the smooth process of detection. 

The maintenance of laboratory equipment is a systematic, professional and long-term work. Full attention shall be paid, and effective measures and methods shall be took to keep the good running status of the equipment, and provide stable and reliable support for the detection work.
