Description

• 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
• For 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
• Highlights: Purity: >99.5% TFA and exceptional clarity allows sensitive, nondestructive peptide detection at low UV wavelengths High-performance packaging: Packaged under nitrogen in amber glass with protective TFE-lined fluorocarbon caps to ensure TFA integrity Choice of formats for convenience: 1 mL ampules can prepare 1 L of 0.1% v/v TFA solution for the mobile phase in reverse-phase chromatography in moments CAS: 76-05-1 Storage Information Store in original container protected from direct sunlight in a dry, cool and well-ventilated area Should be stored from 20° to 25°C Order Info X in the ordering table indicates that hazardous shipping charges apply.
