The Method to Decrease Ibuprofen Concetration Limit in Electrophoresis
Original language description
An online method consisting of transient electrokinetic dosing on-line coupled to ITP was performed for the pre-concentration, pre-separation and analytical determination of a model substance ibuprofen in aqueous samples containing very low concentration of the analyte. Various parameters were investigated in the framework of an optimisation study; the aim was to reach maximal cLOD decreasing in minimum time. The method consists of 2 phases. In the first one, an ibuprofen with addition of dosing electrolyte is electrokinetically dosed to the ITP column where it was stacked on the leading electrolyte. The accumulated zone of ibuprofen is slowly moving through the column. After 800 second of the dosing, the dosing electrolyte has been replaced with the terminating one. The cLOD concentration was dosed to the column on various times. The dosing time was thorougly optimized and 10fold accumulation in 13 minutes was reached.
