一般描述

LiChrosolv 级别针对LC-MS的适用性进行了精确测试,并可满足现代LC-MS电离方法(ESI/APCI-正负模式)的所有要求。由于其离子背景水平低和离子抑制低,LiChrosolv 级别溶剂可提供高重现性和高电离效率。包装材料已经过改进,可以完美满足LC-MS的质量要求。

应用

乙腈可用作以下物质的成分:
  • 蕨类植物中伊鲁烷糖苷(illudane glycoside)及其类似物的快速LC-MS定量测定中的流动相。[1]
  • 从SDB-RPS萃取柱提取(氟)喹诺酮类抗生素化合物的洗脱混合物[2]

制备说明

产品已经过0.2 μm滤器过滤

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. 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.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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
