Abstract: | Summary Experimental Design methodology allows the modelling and optimization of the chromatographic separation of similar pesticides
(triazine family) by GC and HPLC. The GC separation of simazin and atrazin is well modelled by a first degree equation, involving
injected volume, carrier gas pressure and rising oven temperature. The LC is modelled by a second degree equation, depending
on injected volume, eluent flow and composition. These calculated models allow easy optimization of the separations, using
isoresponse curves. |
