Allgemeine Beschreibung
Die Methode entspricht APHA 3500-Cr D und DIN 38405-24.
Dieser Spectroquant® Chromat-Reagenzientest ermöglicht eine genaue Quantifizierung der Chrom(VI)-Konzentration in wässrigen Proben als Chromat- oder Dichromat-Ionen. Zum Nachweis von komplexgebundenem Chrom(III) oder des Gesamtchroms (Summe von Chrom(VI) und Chrom(III)) muss die Probe durch einen Aufschluss zersetzt werden.
Angewandtes Verfahren: In einer schwach phosphorhaltigen Lösung reagieren Chrom(VI)-Ionen mit Diphenylcarbazid, um Chrom(III) und Diphenylcarbazon zu erzeugen, die einen rot-violetten Komplex bilden. Dieser wird photometrisch bestimmt.
Die Spectroquant® Reagenzien-Testkits enthalten hoch stabile, gebrauchsfertige Reagenziengemische, um Analysen gemäß den im beiliegenden Anleitungsblatt beschriebenen Verfahren durchzuführen.
All unsere Küvetten- und Reagenzien-Testkits sind mit einer eindeutigen Live ID (2D-Barcode) versehen, die eine nahtlose Methodenerkennung ermöglicht und wichtige Informationen wie Chargennummer und Verfallsdatum sowie Informationen für automatische Kalibrierungsupdates enthält.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
