If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Cette méthode est analogue aux méthodes EPA 350.1, APHA 4500-NH3 F, ISO 7150-1 et DIN 38406-5.
Ce kit avec réactifs de dosage de l'ammonium Spectroquant® permet de quantifier, sans cyanure, la concentration en ammonium des eaux usées, des eaux souterraines, des eaux de surface et de l'eau de mer. En général, l'ammonium se retrouve dans les sources d'eau suite au lessivage de terres agricoles fertilisées, une forte concentration en ammonium étant un indicateur de pollution fécale important.
Ce test peut également être utilisé dans d'autres domaines, comme l'analyse des aliments et des boissons ou l'analyse d'échantillons environnementaux et agricoles (comme la terre).
Les kits avec réactifs Spectroquant® contiennent des mélanges de réactifs prêts à l'emploi extrêmement stables qui permettent de réaliser les analyses conformément à la procédure décrite dans la notice d'utilisation.
Tous nos tests en tube et nos kits avec réactifs sont équipés du système d'identification "Live ID" (code-barres 2D) qui permet de connaître instantanément la méthode d'analyse et d'obtenir des informations cruciales, comme le numéro de lot, la date de péremption et les réétalonnages automatiques.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
