Daily maintenance of UV-Vis spectrophotometer

Analytical instrument workers need to understand the daily maintenance of the instrument and simple test methods for the main technical indicators. They often maintain and test the instrument to ensure that the instrument works in the best condition.

First, temperature and humidity are important factors that affect the performance of the instrument. They can cause mechanical components to rust, reduce the smoothness of the metal mirror surface, cause the error or performance of the mechanical part of the instrument to decline; cause the aluminum film of the optical components such as gratings, mirrors, and focusing mirrors to rust, resulting in insufficient light energy, stray light, Noise, even the instrument stops working, thus affecting the life of the instrument. Maintenance should be regularly corrected. There should be an equipment room with four seasons of constant humidity, equipped with a constant temperature device, especially a laboratory located in the southern region.

Second, dust and corrosive gases in the environment can also affect the flexibility of mechanical systems, reduce the reliability of various limit switches, buttons, and optocouplers, and it is also one of the reasons that aluminum films must be rusted. Therefore, it must be cleaned regularly to protect the environment and the instrument's indoor sanitary conditions and prevent dust. .

3. After the instrument is used for a certain period of time, a certain amount of dust will accumulate inside the instrument. It is advisable for the maintenance engineer or the engineer to periodically open the instrument housing to remove dust from the interior, and at the same time re-tighten the radiator of each heating element. The sealed window of the box is cleaned, the light path is calibrated if necessary, the mechanical part is cleaned and the necessary lubrication is applied. Finally, the original shape is restored and some necessary tests, adjustments and records are performed.
