一般描述

该认证标准物质(CRM)根据ISO 17034生产,根据ISO/IEC 17025表征。该CRM可追溯至 SI 单位kg,并且以来自国家计量研究院(NMI)如NIST的基准物质为基准进行测量。

请浏览ISO 证书和现场质量自评以查阅当前的鉴定证书。

应用

砷标准品可用作高效液相色谱-电感耦合等离子体质谱(HPLC-ICP-MS)的参考标准品,用于定量海产中的总砷浓度。它已用作有证标准物质(CRM),通过电感耦合等离子体-光学发射光谱(ICP-OES)技术对蓝鳍金枪鱼原材料和油提取样品中的分析物进行定量。[1]

分析说明

1 g/L As 溶于 2% 硝酸,采用高纯度 As2O3、HNO3 和水制备

Testing for heavy metals in food and beverages? You understand that prolonged trace exposure to heavy metals such as arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb), mercury (Hg), and thallium (Tl), via the food, beverages and drinking water we consume can cause serious health risks. Fortunately, increasingly sensitive tests are in place to ensure our food is safe. Discover the recent advances in analytical technologies for heavy metal detection and the products, services and technical support available to help you keep us all safe. Because we all want to trust what we eat.

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.
