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

Application
- Chromatographic Separation: Silica gel is widely used as a stationary phase in chromatography for the separation of various chemical compounds. Innovations in silica gel modification, such as pentabromobenzyl group-modified silica gel, have enhanced the separation efficiency for metabolites like nicotinamide. This application is critical for pharmaceutical analysis and metabolomics studies, providing high precision and accuracy in the quantification of biologically relevant molecules (Ozaki et al., Analytical Biochemistry, 2022).
- Environmental Pollutant Detection: Silica gel is used to create molecularly imprinted polymers (MIPs) that selectively recognize and bind environmental pollutants. A notable application involves the embedding of quantum dots in molecularly imprinted silica gel to detect aminoimidazo-azaarenes (AIAs) in food samples. This method offers high selectivity and sensitivity, making it a powerful tool for food safety and environmental monitoring (Qiao et al., Current Analytical Chemistry, 2021).

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.
