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.

Descrizione generale
The MQuant® Cyanide test includes test strips and all necessary additional reagents. The test is suitable for monitoring cyanide ions in the effluent from electroplating works. Only readily dissociable cyanides are detected. Cyanide ions react with a chlorinating agent to form cyanogen chloride, which in turn reacts with 1,3-dimethylbarbituric acid in the presence of pyridine to form a violet dye (König reaction). The cyanide concentration is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale.The test strips are perfect for pre-testing a sample in an economic and quick way to estimate the cyanide concentration and a possible dilution factor prior to using a quantitative method such as a Spectroquant® test.
We continue to demonstrate our commitment to our planet and a sustainable future by exploring ways to improve existing products in our portfolio. We have recently reviewed the current line of MQuant® test strips to identify key opportunities to minimize impact without compromising on the product performance.This product has benefited from:
- Test strip with reduction
- Recycled aluminum tube

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

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.
