Pierce Trifluoroacetic Acid (TFA), LC-MS Grade, SKU: 85183

Thermo Scientific™ Pierce Trifluoroacetic Acid (TFA) is manufactured and tested to meet strict specifications that ensure superior performance for use as an ion-pairing agent in reverse-phase peptide separations.

nFor complex peptide separations, the key to success can be to vary selectivity. Varying mobile phase composition on the same column can change selectivity enough to resolve peptide that would otherwise overlap. The TFA concentration is usually specified as 0.1% for reverse-phase HPLC of peptides. For reproducible separations from run-to-run or from lab-to-lab, it is essential to make concentrations the same.nnHighlights:n

• • Purity: >99.5% TFA and exceptional clarity allows sensitive, nondestructive peptide detection at low UV wavelengths

n

• • High-performance packaging: Packaged under nitrogen in amber glass with protective TFE-lined fluorocarbon caps to ensure TFA integrity

n

• • Choice of formats for convenience: 1mL ampules can prepare 1L of 0.1% v/v TFA solution for the mobile phase in reverse-phase chromatography in moments
