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.

一般說明
方法：比色法，使用试纸条和试剂，10 - 30 - 60 - 100 - 200 - 400 mg/l NH₄⁺ MQuant®
该测试适用于检测地表水和地下水中由铵化合物导致的潜在的有害污染。随着pH值的变化会形成氨，这是对于鱼类的一种强力毒素。在农业上，样品制备后，MQuant®试纸可用于测定各种类型的粪肥和堆肥中的铵态氮的含量。使用这些试纸，可通过肉眼观察将试纸上的反应区与比色卡进行比较，从而半定量地测量铵浓度。该测试所需的所有必需试剂已包括在内，以便快速、轻松地进行分析。试纸非常适合以经济、快速的方式对样品进行预测试，以便在使用定量方法（例如Reflectoquant® 和Spectroquant®测试）之前对铵浓度和可能的稀释因子进行估算。
可持续发展设计：
通过探索改善产品组合中现有产品的方法，我们始终一致地展现出我们对地球和可持续未来的承诺。最近我们评估了当前的MQuant®试纸产品线，目的是为了发现减少环境影响同时不影响产品性能的重要机会。
本品的环保贡献：
- 试纸用量减少
- 再生铝管包装
- 说明书电子化
欢迎了解详情：试纸小改变，环境大影响。

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
