Abstract
The retardation behavior of ten closely related cyanobacterial hepatotoxins has been studied by parts I and II of the PRISMA system, operating in the irregular part of the PRISMA model. The mobile phase combination and the area of the triangular plane to be studied were selected in the preassays, and the retardation behavior was studied at sixteen selectivity points. The retardation of all the toxins followed a RF = a(PS)2 + b(PS) + c type second-order function with high correlation, the mean for r2 being 0.98 +- 0.02. The three-dimensional retention surfaces described the mobility and the structural variances of the toxins. Cyanobacterial hepatotoxins behaved predictably in the selected system in the irregular part of the PRISMA model.
