AB  - A capillary electrophoresis method to determine four sulfonylureas in grain 
      samples was developed using 10mM of 1-butyl-3-methyl imidazolium 
      tetrafluoroborate (bminBF4) as electrophoretic buffer solution. 2mgL(-1) of 
      Surfactant Coated-Single Wall-Carbon Nanotubes (SC-SWCNTs) was added to the 
      buffer solution to improve the resolution. In this way, the separation of 
      nicosulfuron, ethoxysulfuron, sulfometuron methyl and chlorsulfuron was carried 
      out in 16min without using organic solvents. A clean up-preconcentration 
      procedure was done prior to inject the sample into the CE instrument, in order to 
      achieve the established maximum residue limits (MRLs). So, the detection limits 
      (LODs) for each analytes were between 16.8 and 26.6mugkg(-1). The relative 
      standard deviations (RSDs) were in the range 1.9-6.7%. A recovery study using the 
      so-called matrix matched calibration demonstrates that no matrix interferences 
      were found throughout the determination. The recovery percentages were ranged 
      between 80% and 113%.
