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. Pierce Triethylamine has low UV absorbance properties to provide sensitive detection across all wavelengths when used as an ion-pair reagent in HPLC separations. The reagent is designed and tested to meet the special requirements for peptide sequencing and analysis.
- Greater than 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
