一般描述

LiChrosolv® 溶剂具有较高的紫外线透射率、低颗粒数、低酸碱度和低蒸发残留量,因而其是可重现分离的理想选择。由于在分析型HPLC中分离通常在梯度条件下进行,因此我们提供“梯度级”和“等度级”的溶剂。这使得所使用的溶剂的梯度影响最小化。

应用

乙腈可用作;
  • 固相萃取(SPE)的流动相溶剂,用于茶叶样品中双酚A((BPA)的预浓缩。 [1]
  • 浓缩室内空气样品中挥发性有机化合物的萃取溶剂。 [2]
  • 玻璃器皿的冲洗溶剂。 [2]

制备说明

产品已经过0.2 μm过滤器过滤

Questions

1–3 of 3 Questions  
  1. 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

  2. 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.
