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.

Triethylamine 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
