Manufacturer: Thermo Scientific™ PI25108
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.
- >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
