Trifluoroacetic acid (TFA) is an effective ion pairing agent for HPLC and proteomics LCMS applications which are regularly used to resolve chromatographically similar analytes. In peptide separations, ProteoChems LCMS grade TFA in amber glass ampules is proven to improve peak shape and resolution.ProteoChem’s LCMS Trifluoroacetic acid is among the highest purity TFA available (> 99.9% pure). The high purity and low absorbance cut-off of ProteoChems LCMS grade TFA makes it ideal for preparing mobile phase solvents for HPLC and LCMS studies.Each TFA ampule contains 1.0 gm of Proteomics Grade TFA. Ten TFA amps are sold in each package.
