MN NANOCOLOR® Tube Test org. Complexing agents 10 (Screeningtest)

Available

56.26 €

Price plus VAT, plus delivery

Description

Photometric determination of organic complexing agents. • Photometric determination of the decolouration of the bismuth xylenol orange complex. • 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 If the result is positive, metals present in the sample may be partially or completely withdrawn from the photometric determination.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 Cat. No. 918 08 or NanOx Metal Cat. No. 918 978) has to precede the photometricmeasurement. • Type: tube test 0-52 • Range: 0.5 - 10.0 mg/lIBiK • Sufficient for: 10 - 19 determinations • Sea water suitability: yes, after dilution (1:20)
