| Analysis Note【分析说明】 | Appearance of solution (10 g/l; ethanol): passes test Loss on drying (110 °C): ≤ 1.0 % Suitability as indicator (for metal titration): passes test Suitability for bromate determination in water and drinking water for Pharo- or NOVA-spectrophotometer: passes test Application note: Method A or Method B Method A:For the measurement the method 195, which is pre-calibrated in the Spectroquant 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. |
