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.

General description
QuEChERS 法を用い、食品／農産物サンプルを、多量の塩類（例：塩化ナトリウムおよび硫酸マグネシウム）および／または緩衝剤（例：クエン酸）の存在下で、最初に水性混和性溶媒（例：アセトニトリル）で抽出します。これにより、液相分離が誘発され、それぞれ酸と塩基に不安定な農薬が安定化されます。少量の有機相は、振盪および遠心分離した後、SPE を用いてさらに浄化されます。SPE チューブを使用する従来法とは異なり、分散 SPE では、大量の SPE（例：Supelclean PSA、ENVI-Carb、および／または Discovery DSC-18）を抽出物と混合することにより、浄化が促進されます。サンプル浄化後、混合物を遠心分離し、得られた上清は直接分析するか、または分析前に小さな追加処理をすることができます。
Supelco は、あらかじめ定めた量の塩類と SPE 吸着剤を含む一連のバイアルと遠心チューブを備え、今日使用されている最も一般的な方法構成をサポートしています。

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