一般說明

EPA 521亚硝胺混合物是一种含有N-亚硝基二甲胺、N-亚硝基二丁胺、N-亚硝基正丙胺、N-亚硝基甲基乙胺、N-亚硝基二乙胺、1-亚硝基吡咯烷和1-亚硝基哌啶的多组分溶液，可作为认证标准物质（CRM）。对用于制备EPA方法521亚硝胺混合物的原材料和溶剂进行了鉴别和纯度筛选。该混合物通过重量法制备，并通过气相色谱法（GC）进行定量分析。
US EPA 500系列方法是对原水、成品饮用水和所有处理阶段的饮用水中的挥发性有机化合物（VOC）、农药、合成有机化合物（SOC）和三卤甲烷消毒副产物（THM）等有机污染物进行鉴别和定量的分析方法。

應用

EPA 521亚硝胺混合物可用作CRM，通过分析技术定量测定快餐食品、[1]肉类制品、[2][3]叔烷醇胺基二氧化碳（CO2）捕获系统、[4]环境水样[5]以及饮用水和饮用水处理工厂（6）中的N-亚硝胺分析物。
有关合适的仪器技术的更多信息，请参阅产品′的检验报告。想要获得更多支持，请联系技术服务部。

其他說明

该认证标准物质（CRM）根据ISO 17034 和 ISO/IEC 17025进行生产和认证。有关此CRM使用的所有信息均可在检验报告上找到。

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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

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

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
