ABSTRACT
Objective:Spectrophotometer is a device to be verified obligatory in hospital. This article introduced some techniques to avoid ordinary mistakes in measurement. Methods:We introduced principle and verification regulation of spectrophotometer. Such methods as parameter configuration, proper maintenance can reduce our mistakes. Results: This article analyzed some common problems in measurement and also offered solutions. Conclusion: In the measurements of spectrophotometers, because the operators have less spectrophotometer operation experience, they often get inaccurate data which lead to an error. Conclusion: To avoid these mistakes, strictly regulate operations in spectrophotometer’s verification and proper routine maintenance are necessary.
