Mixed-Mode HPLC Separation of Tertiary Amines on Primesep 200 Column

December 6, 2007

Tertiary amines are compounds derived from ammonia. Amines with short alkyl (triethylamine, trimethylamine, diisopropylethylamine) chain are not hydrophobic enough to retain well in reverse phase chromatography. Slight hydrophobicity and strong basic properties of tertiary amines provide enough interaction with mixed-mode stationary phases to guarantee good retention on a Primesep 200 column. Tertiary amines can be separated by dual interaction based on minimal difference in hydrophobic and basic properties. This application can be used for analysis of complex mixtures of tertiary amines. ELSD and LC/MS detection can be applied. Various buffers compatible with specified detection technique can be employed (TFA for ELSD, ammonium acetate or ammonium formate for LC/MS) Compounds with the nitrogen atom next to carbonyl are called amides and are not basic in nature. Mixed-mode cation-exchange stationary phases are not interacting with amides by ion-exchange mechanism.

Separation of Simple Tertiary Amines

September 25, 2005

Primesep 200 separates simple tertiary amines (trimethylamine, triethylamine, diisopropylethylamine, N,N-dimethylbenzylamine) by cation exchange and reversed phase. Primesep 200 has an embedded anionic functional group which helps retain cations by polar and ion-exchange mechanisms. Excellent peak shape results with a mass spec compatible mobile phase of water, acetonitrile (MeCN, ACN) and trifluoracetic acid (TFA) with evaporative light scattering detection (ELSD).

Primesep C Column Retention Control

March 27, 2004

Primesep C separates benzylamines with an easily tunable HPLC method that allows retention control. Benzylamine, N-methylbenzylamine, and N,N-dimethylbenzylamine peak order and retention can be significantly changed by altering the water/acetonitrile ratio in the mobile phase which changes the combination of cation exchange, complex formation, and hydrophobic interactions. This mixture is separated with a mobile phase of water, acetonitrile (MeCN, ACN) and triethylamine (TEA) phosphate with UV detection at 210 nm.

Condition

Column Primesep C, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer TEAPh
Flow Rate 1.0 ml/min
Detection UV 210
