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
Der MQuant®-Cyanidtest enthält Teststreifen und alle erforderlichen zusätzlichen Reagenzien. Der Test eignet sich für die Überwachung von Cyanid-Ionen im Abwasser von Galvanisierungseinrichtungen. Es werden nur leicht dissoziierbare Cyanide erfasst. Cyanidionen reagieren mit einem Chlorierungsmittel zu Chlorcyan, das wiederum in Gegenwart von Pyridin mit 1,3-Dimethylbarbitursäure zu einem violetten Farbstoff reagiert (König-Reaktion). Zur semiquantitativen Messung der Cyanid-Konzentration wird die Reaktionszone des Teststreifens mit den Felder einer Farbskala visuell verglichen. Die Teststreifen eignen sich ideal zum kostengünstigen und schnellen Vortesten einer Probe, damit die Cyanid-Konzentration und ein möglicher Verdünnungsfaktor noch vor einer quantitativen Methode wie einem Spectroquant® Test abgeschätzt werden können.
Wir setzen uns für Umweltschutz und Nachhaltigkeit ein und suchen ständig nach Möglichkeiten, um die Produkte in unserem Portfolio zu verbessern. Kürzlich haben wir untersucht, wie wir die Umweltauswirkungen der Produktreihe der MQuant®-Teststreifen minimieren können, ohne die Produktleistung zu beeinträchtigen. Es wurden folgende Verbesserungen durchgeführt:
- Verringerung der Teststreifenbreite
- Recyceltes Aluminiumröhrchen
- Digitale Bedienanleitung

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

What does "Min shelf life" mean for this product?
1 answer-
The term "Minimum shelf life" (MSL) denotes the period following the date of analysis during which the product meets the respective specifications. MSL is determined through careful analysis of samples under well-documented conditions in accordance with extensive product knowledge. Typically, "Minimum Shelf Life" can be found on the Certificate of Analysis and/or the labels.
