Macherey-Nagel NANO Crack set
Photometric determination of the decolouration of the bismuth xylenol orange complexReaction basis according DIN 38409-H26. The complexing agents are determined relative to the bismuth complexing index IBiC. The following conversion factors hold true: 1 mg/L IBiC = 1.4 mg/L EDTA (M = 292 g/mol) = 1.0 mg/L NTA This method is a screening test which covers strong complexing agents. If the result is positive, metals present in the sample may be partially or completely withdrawn from the photometric determination. For the analysis of metals in this case a decomposition (e. g. with Crack set REF 91808 or NanOx Metal REF 918978) has to precede the photometricmeasurement.Here you can download the Safety Data Sheet: Safety Data SheetMeer tonen
