MICELLAR ELECTROKINETIC CAPILLARY CHROMATOGRAPHY OF HIGH EXPLOSIVES UTILIZING INDIRECT FLUORESCENCE DETECTION

Indirect fluorescence detection was applied to the detection of the hi gh explosives nitroguanidine (NGU), ethylene glycol dinitrate (EGDN), cyclotetramethylene tetranitramine (HMX), cyclotrimethylene trinitrami ne (RDX), nitroglycerine (NG), 2,4,6-trinitrotoluene (TNT), pentaeryth ol tetranitrate (PETN) and trinitrophenyl-methylnitramine (tetryl), se parated by MEKC. Two fluorophores, fluorescein and rhodamine B, were i nvestigated. All explosives except NGU and PETN were detected but sens itivity was poor. Some of this lack in sensitivity may be associated w ith laser instability.
