Aromatic amines are important metabolites of nitroaromatic explosives, hence monitoring of aromatic amines' content at former ammunition plants is necessary. Twenty years ago, a threshold limit value of 0.1 μg/L for the sum of diazotizable aromatic

Gradient elution in micellar electrokinetic chromatography has been proposed as a technique for extending the elution range and adjusting retention factors for optimum values. It is shown that this approach in practice has not only to be evaluated fo
