What is Spectrometer Accuracy and Precision?
Accuracy is affected by both random and systematic errors, while precision is affected by random errors. To illustrate the difference, consider the wavelength calibration of the spectrometer.
Specifying accuracy and precision criteria for ultraviolet
In the absorbance range encompassing 0.2 to 0.8, the photometric accuracy shall not differ by more than ± 0.5 % of samples whose absorbance has been established by a standardising laboratory.
What Is the Most Accurate Spectrometer?
The accuracy of a spectrometer is determined by its ability to precisely measure the wavelength and intensity of light or other signals, and how well it can differentiate between small
