AU160: Determination of N,N-Dimethyl-o-Toluidine andN,N-Diethyl-p-Toluidine in Ethylene Gas Samples

Instrument Type: IC

Amines are found throughout nature and are synthesized for many commercial applications. They are used as pharmaceuticals, anti-corrosive agents, and chemical intermediates, and can indicate food spoilage. IC is an excellent technique for determining amines in a variety of samples, even low concentrations. Here is shown the separationand detection of two such amines: N,N-dimethyl-otoluidine and N,N-diethyl-p-toluidine. These amines are separated on a CS17 column with an MSA gradient and 9% acetonitrile, and are detected by absorbance at 210 nm.
