The key idea is to apply the sweeping preconditioner recursively to the quasi-two-dimensional auxiliary problems introduced in the three-dimensional (3D) sw...
We have applied sweeping micellar electrokinetic chromatography (sweeping-MEKC) to the simultaneous determination of Delta(9)-tetrahydrocannabinol (THC) and its major metabolites, 11-hydroxy-Delta(9)-tetrahydrocannabinol (THC-OH) and 11-nor-9-carboxy-Delta(9)-tetrahydrocannabinol (THC-COOH). We monitored the effects of several of the sweeping-MEKC parameters, including the proportion of organic...
