一般說明

Amberlite XAD-2是苯乙烯-二乙烯基苯树脂的疏水共聚物，需要较长的纯化过程，可用作吸附剂。Amberlite XAD-2 树脂，依据其疏水基团的芳香性和大小，通过低能的物理相互作用吸附有机化合物。[1]
非离子型大网格树脂，通过疏水性和极性相互作用来完成离子吸附与解吸；通常用于等度条件下。
规格：

應用

Amberlite™ XAD®-2用作：
  • Soxhlat萃取技术提取有机氯化合物的吸附剂[1]
  • 在高效液相色谱分析柱相层析提取粘附样本的吸附剂[2]
  • 层析吸附剂[3]
用于分子量高达 20,000 的疏水性化合物的多环芳烃吸附剂树脂，具体用途包括酚类和有机物的去除，表面活性剂、芳香化合物和抗生素的回收。可用作催化或金属去除的助剂。经整理的美国环保局版本请参见 Supelpak-2 和 Supelpak-2B。

Questions

1–7 of 7 Questions  

  1. 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

  2. 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

  3. What is the most approriate protocol to wash Amberlite before use? Thanks in advance!

    1 answer

    1. Amberlite XAD-2 is a crude preparation and must be thoroughly cleaned prior to use.

      1. Rinse with hot deionized water (may hold in nylon filter cloth to retain particles) - use at least 3 bed volumes per hour at 110 deg C
      2. Soak overnight in 2 bed volumes (BV) of ethanol.
      3. Load resin into a glass column and rinsed with a further 2 BV of ethanol.
      4. Rinse with 2 BV of deionized water to remove the ethanol, 1 BV of 4% (w/v) sodium hydroxide, 2 BV of deionized water, 1 BV 4% (v/v) hydrochloric acid, and finally rinse with deionized water until the pH of the eluent is neutral.

      For further use it is advantageous to do a wash in the same solvent use in the application.
      Store in sealed container; may be refrigerated but NOT frozen. As a bacteriostat, one may rinse with 20% ethanol (deionized water) prior to storage.

  6. May I purchase Amberlite XAD-2 in large quantities?

    1 answer

    1. The largest package size of Amberlite XAD2 is 25 kg (Product No. 3025-U).

      Helpful?

  7. Is Amberlite XAD-2 ready-to-use?

    1 answer

    1. No.  Amberlite XAD2 is shipped imbibed with 5% NaCl & 1% NaCO3; it has not been specially processed nor cleaned. We suggest that it be extensively treated to a suitable preliminary elution and wash.
