反应性相对较低的有机物必须被收集在第A类, 如果被卤化则在第B类, 如果为固体残留物则归在第C类.规格 规格 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® 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.
