Optimization of IC separation based on isocratic-to-gradient retention modeling in combination with sequential searching or evolutionary algorithm
Gradient ion chromatography was used for the separation of eight sugars: arabitol, cellobiose, fructose, fucose, lactulose, melibiose, N-acetyl- D-glucosamine, and raffinose. The separation method was optimized using a combination of simplex or genetic algorithm with the isocratic- to-gradient retention modeling. Both the simplex and genetic algorithms provided well separated chromatograms in a similar analysis time. However, the simplex methodology showed severe drawbacks when dealing with local minima. Thus the genetic algorithm methodology proved as a method of choice for gradient optimization in this case. All the calculated/predicted chromatograms were compared with the real sample data, showing more than a satisfactory agreement.
