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.

一般描述
助留机理：反相
样品基质相容性：含水溶液（饮用水、地下水、废水）
- 表面积：100m2/g；粒度：120/400 目
- 当在反相条件下使用时对于非极性和极性基质中的有机极性和非极性化合物都具有极强的亲和性
- 碳表面包含六角环状结构，位于石墨层之间并将其连接起来
- 该碳相的无孔性质使其可以快速处理，吸附时不需要分析物扩散到固相微孔中
- 独立的研究人员已经发现，ENVI-Carb 对于来自包括地下水、水果和蔬菜等各种基质中的 200 多种杀虫剂的快速样品制备极其有用

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
