Triethylamine (TEA)



Ideal for HPLC separation and analysis of peptides!

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. Triethylamine from Pierce comes in two grades. Ionate grade is designed for use as an ion-pair reagent in HPLC separations and has a low UV absorbance to provide you with the most sensitive detection across all wavelengths. Sequanal grade is designed to meet the special requirements for peptide sequencing and analysis.
