This product would not be recommended for separation of ammonia gas from air. Typically, a scrubbing system with a chemical such as dilute sulfuric acid would be used. If an adsorbent is preferred, activated charcoal would be the best recommendation and impregnated activated charcoal is ideal.

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

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

What are the proper storage conditions for Dowex® 50W X8 resin, Product 44504?
1 answer-
The resins should be stored in a dry cool place. The storage temperature should be kept below 50oC (120oF).Storage temperature below 0oC can cause resin freezing and temperatures below -18oC (0oF) should be avoided. Repeated freeze-thaw can cause damage on the beads. The frozen resin beads should be completely thawed out at room temperature condition before loading and use.
