Application note: Method A or Method B
Method A: For the measurement the method 195, which is pre-calibrated in the Spectroquant® Pharo-and NOVA-photometers can be used. To increase the precision of the results a self-made blank according to the application is recommended generally.
Method B: For the measurement the pre-calibrated method 195 is not applicable. Instead of that, a self-made calibration according the application is to perform.
