General description

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。

Application

仅用作HPLC和UHPLC-MS 应用的提取溶剂或流动相。
据报道可用于以下LC–MS/MS 研究:
  • 多种色谱吸附剂上分级的血浆和血清样品
  • 动物生物样品中的肽

丙酮的发光强度取决于溶液组分。丙酮吸收UV光,导致丙酮光分解和放射性产物。

Features and Benefits

  • 通过UHPLC-MS 和 UHPLC-UV适用性测试,规定用于UHPLC-MS 和 UHPLC-UV:实现分析灵活性
  • 正离子和负离子电喷雾离子化(ESI)和大气压化学电离质谱(APCI-MS)的规定质量使得所有重要MS模式下的分析实现最低检测限和信心(测试1)
—ESI/APCI (+) < 2 ppb
—ESI/APCI (-) < 10 ppb
  • 最低杂质谱: 产生无干扰基线(测试2)
  • 通过 0.2 μm过滤器微滤(测试3)以实现:
—过滤器和HPLC系统部件的长使用寿
—减少柱堵塞风险

  • 装入硼硅酸盐玻璃瓶以实现最低的金属离子污染
  • 最低水平的微量金属杂质使形成的金属离子加合物最少
—<5 ppb
  • 最少5 ppb的UHPLC-MS溶剂系列中最低水平的聚乙二醇(PEG)杂质(PEG S/N 信噪比 50) <

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  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
