Thermo Scientific™ Pierce Triethylamine (TEA) is a high-purity solvent that can be used in certain HPLC protocols, such as weak anion exchange to resolve certain tryptic peptides on a reverse-phase column.

Triethylamine is an ion-pairing reagent that alters selectivity in reverse-phase HPLC separations. By pairing with peptides, it effectively sharpens peaks, resulting in improved peak resolution.

Highlights:

  • >99.5% triethylamine purity, allowing sensitive peptide detection at low UV wavelengths in reverse-phase HPLC peptide separation systems Packaged in amber glass bottles with protective PTFE-lined fluorocarbon caps for reagent integrity
  • Has a low UV absorbance to provide the most sensitive detection across all wavelengths
