UV-visible spectrometer:
1. Temperature and humidity are important factors affecting the performance of the instrument:
can cause corrosion of mechanical parts, reduce the smoothness of metal mirror surface, and cause error or performance degradation of mechanical parts of the instrument; The aluminum film of optical components such as gratings, mirrors, focusing mirrors, etc. is corroded, resulting in insufficient light energy, stray light, noise, etc. and even the instrument stops working, this affects the life of the instrument. Maintenance should be regularly corrected. The use of ultraviolet spectrophotometer should have four seasons constant humidity instrument room, equipped with constant temperature equipment, especially in the southern region of the laboratory.
2. Dust and corrosive gases in the environment can also affect the flexibility of mechanical systems, reduce the reliability of various limit switches, keys and photoelectric couplings, and are also one of the reasons for corrosion of aluminum films of required components:
Therefore, the ultraviolet spectrophotometer must be cleaned regularly to ensure the environment and indoor sanitary conditions of the instrument and prevent dust.
3. After the ultraviolet spectrophotometer instrument is used for a certain period of time, a certain amount of dust will accumulate inside. The maintenance engineer or under the guidance of the engineer will regularly open the outer cover of the instrument to remove dust inside:
At the same time, re-tighten the radiator of each heating element, clean the sealing window of the optical box, calibrate the optical path when necessary, and clean and lubricate the mechanical parts as necessary. Restore to the original state, and then carry out some necessary testing, adjustment and recording. Analytical instrument workers should understand the daily maintenance of the instrument and the simple test method of the main technical indicators, and often maintain and test the instrument to ensure that the instrument works in the state.
