一般描述
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 (-) < 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:
—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
- 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
