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.

Is this resin capable of separating choline
1 answer-
No references are available for using the hydrogen form of this resin to separate choline from other relevant cations. However, ion-exchange chromatography is suitable for this separation. Reviewing peer-reviewed literature on this topic is recommended. Contact Technical Service for assistance with detailed method development.

Is this type of resin suitable for separating ammonia gas from air?
1 answer-
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

What is the suggested operating temperature for Dowex® 50W X8 resin, Product 44504?
1 answer-
At elevated temperature, operation can cause degradation of functional sites and loss of the ion exchange capacity. The resin degradation depends on many variables, such as the level of dissolved oxygen and the presence of catalytic metals on the resin. In general, ~120oC (250oF) is suggested as the maximum operating temperature.
