产品描述

General description

Trifluoroacetic acid is commonly used as a mobile phase additive in liquid chromatography-mass spectrometry (LC-MS).
Features:
• Extensive QC testing ensures the highest specifications.        
• Optimized to improve ionization and resolution.        
• Extremely low levels of inorganic and organic impurities.       
• Manufactured specifically for accurate and fast LC-MS.
•广泛的质量控制测试可确保获得最高规格。
•优化以改善电离和分离度。
•无机和有机杂质含量极低。
•专为精确,快速的LC-MS制造。

三氟乙酸可用作流动相添加剂,通过亲水相互作用液相色谱-电喷雾电离耦合串联质谱法(HILIC-ESI / MS / MS)和反相液相色谱-串联质谱分析生物样品中的碱性化合物 质谱(RP-LC-MS / MS)。

Application

Trifluoroacetic acid may be used as a mobile phase additive for the analysis of basic compounds in biological samples using hydrophilic interaction liquid chromatography-electrospray ionization coupled to tandem mass spectrometry (HILIC–ESI/MS/MS) and reversed-phase liquid chromatography coupled to tandem mass spectrometry (RP-LC-MS/MS).[1]
