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。它适用于可重现的分离。
我们竭诚为您带来符合一项或多项绿色化学12项原则要求的绿色替代产品。庚烷是比己烷更环保的溶剂,因此符合“更安全的溶剂和助剂”原则。点击此处以获取更多信息。

应用

仅用于U/HPLC 和 LC-MS/MS 应用。
据报道也可作为提取混合物的成分用于GC-MS法筛查尿液中的滥用药物。

特点和优势

  • 通过适用性测试,规定用于UHPLC-MS 和UHPLC-UV:分析灵活性
  • 在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)中的规定质量,在所有重要MS模式(测试1)下实现分析物的最低检测限和置信度
—ESI/APCI (+) < 2 ppb
—ESI/APCI (-) < 10 ppb
  • 最低杂质含量:无干扰基线(测试2)
  • 通过 0.2 μm过滤器进行微滤(测试3)以提供:
—让过滤器和HPLC系统的机械部件有长使用寿命
—减少柱堵塞的风险
  • 硼硅酸盐玻璃瓶包装最大程度减少金属离子污染
  • 最低水平的痕量金属杂质使金属离子含量最低
—5 ppb
  • UHPLC-MS 溶剂系列(PEG S/N 信噪比 < 50)中聚乙二醇(PEG)杂质含量最低
