产品说明

一般描述

Compared to trifluoroacetic acid (TFA), difluoroacetic acid (DFA) exhibits an improved sensitivity in mass spectral detection (ESI) as it has a reduced effect on ion suppression in reversed-phase liquid chromatography (RPLC-MS), while keeping its strong chromatographic performance enhancing effects.
