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

应用
- 色谱分离：硅胶广泛用作色谱固定相以分离各种化学物质。新型改性硅胶，如五溴苄基改性硅胶，可提高烟酰胺等代谢产物的分离效率。可高度精密和准确地定量生物相关分子，对药物分析和代谢组学研究有重要意义(Ozaki et al., Analytical Biochemistry, 2022)。
- 环境污染物检测：用硅胶制备的分子印迹聚合物(MIP)可选择性地识别与结合环境污染物。代表性的一个应用是在分子印迹硅胶中包埋量子点，用于检测食品样品中的氨基咪唑-氮杂脂芳烃(AIA)。该方法具有高选择性和特异性，是适合食品安全和环境监测的强大工具(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.
