Implementation and Result Analysis of Value Comparison of Spectrophotometers
Value comparison is a component of capability verification activities,which refers to the activity of two or more calibration and testing institutions testing a tested and stable transmission standard within a specified time and range according to agreed conditions,and then judging the accuracy of the institution's value transmission through the comparison of the result values.By comparing the wavelength indication error values of UV visible spectrophotometers,it analyzes the results of the problems discovered during the comparison process.
