说明

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） <
