Application

甲醇是一种高纯度溶剂，在超高效液相色谱-串联质谱（UHPLC-MS）分析中用作流动相组分。
该产品可用作溶剂用于以下研究：
  • 环境水样中全氟和多氟烷基物质（PFAS）的高分辨率质谱分析
  • 污水污泥和土壤样品中全氟辛烷磺酸和/或全氟辛烷磺酸（PFOS）的UHPLC-MS/MS研究

Features and Benefits

  • UHPLC-MS和UHPLC-UV适用性的测试和指定：用于分析灵活性
  • 正负电喷雾电离（ESI）和大气压化学电离-质谱法（APCI-MS）中所有重要MS模式分析的最低检出量和置信度的规定质量（测试1）。
—ESI/APCI (+) < 2 ppb
—ESI/APCI (-) < 10 ppb
  • 最低杂质分布：用于无干扰基线（测试2）
  • 通过0.2 μm过滤器微滤（测试3）以提供：
—更长使用寿命的过滤器和HPLC系统机械部件
—降低柱堵塞的风险
  • 采用硼硅酸盐玻璃瓶封装，尽可能降低金属离子污染
  • 最低水平的微量金属杂质，形成最少的金属离子加合物
— <5 ppb
  • 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）

General description

UHPLC-MS LiChrosolv®溶剂设计用于满足UHPLC-MS在研究和质量控制方面的最高要求，包括蛋白质组学和代谢组学以及环境、临床、食品或工业测试应用
