一般說明

Brockmann 氧化铝适用于柱色谱和吸附过滤。
氧化铝通常用作色谱方法中采用的基于固相萃取 (SPE) 的净化程序中的固相载体相。[1]

應用

在通过高效液相色谱-蒸发光散射检测法 (HPLC-ELSD) 测定前，使用氧化铝作为色谱柱支持纯化锡-2 单棕榈酸甘油酯。[2]
可用于鱼组织提取液纯化后的液体 −在通过液相色谱串联质谱法 (LC-ms) 分析三芳甲烷和吩噻嗪染料之前，将液体萃取至二氯甲烷中MS/MS）。[1]它也可以作为固相支持物，用于气相色谱-串联质谱法 (GC-MS/MS) 分析植物油中的拟除虫菊酯杀虫剂残留。[3]

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.
