High impact information on p-tolylmethanamine

• The carrier electrolyte, consisting of 10 mM 4-methylbenzylamine and 1.5 mM citric acid at pH 4.8, was found to be optimal to accommodate both analyte cations in the ITP range and then separate them in the CZE mode, with relative standard deviations for migration times from 0.06-0.15% and for peak areas from 4-8% [1].
• The target analytes, positively charged under acidic electrolyte conditions, were separated with positive separation voltage polarity using 10 mM 4-methylbenzylamine, 4.5 mM citric acid, 25% (v/v) methanol at pH 4.05 as background electrolyte providing optimal separation [2].
