Milk and milk products - Determination of nitrate and nitrite contents - Part 1: Method using cadmium reduction and spectrometry (ISO 14673-1:2004)

ISO 14673-1|IDF 189-1:2004 specifies a method for the determination of the nitrate and nitrite contents of milk and milk products by cadmium reduction and spectrometry. The method is applicable to: whole and partly skimmed and skimmed dried milk; hard, semi-hard and soft cheeses; processed cheese; whey cheese, caseins and caseinates and dried whey.
The method may be performed using automatic equipment, in particular by segmented flow analysis (SFA) or flow injection analysis (FIA), thus reducing cadmium contamination in laboratory work places and waste water.

Milch und Milchprodukte - Bestimmung des Nitrat- und Nitritgehaltes - Teil 1: Verfahren mit Cadmiumreduktion und Spektrometrie (ISO 14673-1:2004)

Dieser Teil von ISO 14673|IDF 189 legt ein Verfahren zur Bestimmung des Nitrat- und Nitritgehaltes von Milch und Milchprodukten durch Cadmiumreduktion und Spektrometrie fest.
Das Verfahren gilt für
¾ vollständig und teilentrahmte Milch und Magermilchpulver;
¾ Hart-, Schnitt- und Weichkäse;
¾ Schmelzkäse;
¾ Molkenkäse, Caseine und Caseinate sowie Molkenpulver.
Das Verfahren kann unter Anwendung automatischer Geräte durchgeführt werden, besonders mit der segmentierten Fließanalyse (SFA) oder der Fließinjektionsanalyse (FIA), wodurch die Verunreinigung des Laborarbeitsplatzes und des Abwassers mit Cadmium verringert wird.
ANMERKUNG   Diese Verfahren sind in ISO 14673-2|IDF 189-2 bzw. in ISO 14673-3|IDF 189-3 beschrieben.

Lait et produits laitiers - Détermination des teneurs en nitrates et en nitrites - Partie 1: Méthode par réduction au cadmium et spectrométrie (ISO 14673-1:2004)

L'ISO 14673-1|FIL 189-1:2004 décrit une méthode de détermination des teneurs en nitrates et en nitrites dans les produits laitiers par réduction au cadmium et spectrométrie. La méthode s'applique: au lait entier, au lait demi-écrémé et au lait écrémé sec; aux fromages à pâte dure, semi-dure et aux fromages à pâte molle; aux fromages fondus; au lactosérum, aux caséines, aux caséinates et au lactosérum sec.
Cette méthode peut être réalisée à l'aide d'un appareil automatisé, en particulier par analyse de fluide segmentée (SFA) ou par analyse par injection (FIA), ce qui permet de réduire la contamination par le cadmium des laboratoires et des eaux usées.
