Description

Description générale

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.

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).
