Descripción general

Amberlite XAD-2, un copolímero hidrófobo de la resina estireno-divinilbenceno, requiere un proceso de purificación más prolongado y se utiliza como absorbente. La resina Amberlite XAD-2 dependiente de la aromaticidad y del tamaño de los grupos hidrófobos absorbe compuestos orgánicos mediante interacciones físicas de baja energía.[1]
Resina macrorreticular no iónica que adsorbe y libera especies iónicas a través de interacciones hidrófobas y polares; se utiliza normalmente en condiciones isocráticas.
Especificaciones:

Aplicación

Amberlite™ XAD®-2 se utilizó:
  • como adsorbente en la extracción de compuestos organoclorados utilizando la técnica de extracción Soxhlat[1]
  • como adsorbente en la extracción de muestras de miel utilizando cromatografía en columna para análisis HPLC[2]
  • en cromatografía de adsorción[3]
Resina adsorbente poliaromática para compuestos hidrófobos de hasta 20 000 de peso molecular: fenoles, retirada de compuestos orgánicos, tensioactivos, compuestos aromáticos, recuperación de antibióticos. Puede utilizarse como soporte para remoción de catalizadores o metales. Para versiones limpias de la US EPA (Agencia norteamericana de protección medioambiental) véase Supelpak-2 y 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.

  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.

  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.
