Spectrophotometer is a precision optical instrument, which has been carefully assembled and debugged before leaving the factory. If the instrument can be properly maintained and maintained, it can not only ensure the reliability and stability of the instrument, but also extend the service life of the instrument.
1. Provide a good environment for the instrument. If the instrument should be installed on a sturdy and stable workbench, and there is no strong vibration or continuous vibration, no corrosive gas such as hydrogen sulfide, fluoride nitrite, etc. should be in the room.
2. During the test, pay attention to prevent the solution from splashing into the sample holder and the sample chamber. The cuvette containing the test solution should not be left in the sample chamber for a long time.
3. Pay attention to protect the optical window (head light side) of the cuvette. In addition to not rubbing on, it is mainly to prevent the optical window from being contaminated. After use, it should be cleaned in time. Do not allow the remaining samples or washing liquid to be adsorbed on the optical bed to maintain good matching.
4. After each use, check whether there is enough overflow solution in the sample chamber, and test the sample chamber frequently to prevent the corrosion of components or optical components by the waste liquid.
5. After use, the dust cover should be covered, and a desiccant bag can be placed in the sample room to prevent moisture, but it must be removed at the beginning.
6. The liquid crystal display and keyboard of the instrument should be protected against scratches, water, dust and corrosion during daily use and storage.
7.Perform regular performance indication tests, find problems and contact dealers. Non-professional maintenance personnel should not open the case for repair without authorization.
8. When the instrument is not suitable for a long time, pay special attention to the ambient temperature and humidity. It is best to place a desiccant bag in the sample room and replace it regularly.
