Maintenance of liquid chromatograph (HPLC)
1. Effect of heat treatment system on the microstructure and properties of GH2132 alloy. The fracture of daily operation strip sample of PLC is always on both sides: temperature: 10-30 ℃; Relative humidity: 80%; 2. Outer box material: steel plate, baking paint, cold drawn reinforcement: each batch of cold drawn reinforcement should be subject to 2 tensile tests, which are constant temperature and humidity, away from high-voltage interference and high vibration equipment.
2. Pump maintenance:
1) use mobile phase to clean as much as possible
