Non fatty foods - Determination of chlormequat and mepiquat - LC-MS/MS method

This draft European Standard specifies a method using high performance liquid chromatography/tandem mass spectrometry (LC-MS/MS) for the determination of the growth regulators chlormequat and mepiquat in non-fatty foods as chlormequat and mepiquat cation, respectively.
The method is applicable to all kinds of fruits, vegetables and cereal products. It has been collaboratively studied on mushrooms, pears, wheat flour, fruit puree and, additionally, on infant formula, see [1].

Fettarme Lebensmittel - Bestimmung von Chlormequat und Mepiquat - LC-MS/MS-Verfahren

Diese Europäische Norm legt ein hochleistungs-flüssigchromatographisches Verfahren mit Detektion durch
Tandem-Massenspektrometrie (LC-MS/MS) zur Bestimmung der Wachstumsregulatoren Chlormequat und
Mepiquat in fettarmen Lebensmitteln als Chlormequat- bzw. Mepiquat-Kation fest.
Das Verfahren ist anwendbar auf alle Arten von Obst, Gemüse und Getreideerzeugnissen. Es ist in einem
Ringversuch mit Pilzen, Birnen, Weizenmehl, Obstpüree und zusätzlich an einer Kindernahrung (Milchpulver)
geprüft worden, siehe [1].

Aliments non gras - Détermination du chlorméquate et du mépiquate - Méthode CL-SM/SM

La présente Norme européenne spécifie une méthode utilisant la Chromatographie liquide à haute performance/Spectrométrie de masse en tandem (CL-SM/SM) pour la détermination des substances ou régulateurs de croissance chlorméquat et mépiquat dans des aliments non gras respectivement sous la forme de cation chlorméquat et de cation mépiquat.
La méthode s'applique à toutes les sortes de fruits, légumes et produits céréaliers. Elle a fait l'objet d'études réalisées en collaboration sur des champignons, des poires, de la farine de blé, de la purée de fruit et, en outre, sur des préparations pour nourrissons (voir [1]).
