Daily maintenance of UV-Vis spectrophotometer

Analytical instrument workers should understand the routine maintenance of the instrument and the simple test method for the main technical indicators, and often maintain and test the instrument to ensure that the instrument works in a good state of Zui 1 The dust and corrosive gas in the environment will affect the flexibility of the mechanical system, reduce the reliability of various limit switches, keys and optoelectronic couplings, which is one of the reasons for the corrosion of the aluminum film of the necessary components Therefore, it is necessary to clean regularly, protect the environment and indoor sanitary conditions of the instrument, and pay attention to dust prevention (spectrophotometer, UV-Vis spectrophotometer, 721 spectrophotometer, atomic absorption spectrophotometer, fluorescence spectrophotometer, UV spectrophotometer, Kunke spectrophotometer, principle of spectrophotometer, use method of spectrophotometer, brand of spectrophotometer, price of spectrophotometer) 2 After the instrument is used for a certain period, a certain amount of dust will accumulate in the instrument After the maintenance engineer or under the guidance of the engineer, open the outer cover of the instrument on a regular basis to remove dust from the interior At the same time, retighten the radiator of each heating element, clean the sealing window of the optical box, calibrate the optical path if necessary, clean and lubricate the mechanical part , after Zui, restore to the original state, and then carry out some necessary tests, adjustments and records (spectrophotometer, UV-Vis spectrophotometer, 721 spectrophotometer, atomic absorption spectrophotometer, fluorescence spectrophotometer, UV spectrophotometer, kunke spectrophotometer, principle of spectrophotometer, use method of spectrophotometer, brand of spectrophotometer, price of spectrophotometer) 3 Temperature and humidity are important factors affecting the performance of the instrument They can cause the corrosion of mechanical parts, decrease the surface finish of metal mirror, cause the error or performance of mechanical parts of the instrument; cause the corrosion of aluminum film of optical parts such as grating, reflector, focus mirror, etc., produce light energy shortage, stray light, noise, etc., and even stop the instrument, thus affecting the service life of the instrument The maintenance should be corrected regularly The instrument room with constant humidity in all seasons shall be equipped with constant temperature equipment, especially the laboratory located in the south (spectrophotometer, UV-Vis spectrophotometer, 721 spectrophotometer, atomic absorption spectrophotometer, fluorescence spectrophotometer, UV spectrophotometer, kunke spectrophotometer, principle of spectrophotometer, use method of spectrophotometer, brand of spectrophotometer, price of spectrophotometer)
