Abstract
Indirect fluorescence detection was applied to the detection of the high explosives nitroguanidine (NGU), ethylene glycol dinitrate (EGDN), cyclotetramethylene tetranitramine (HMX), cyclotrimethylene trinitramine (RDX), nitroglycerine (NG), 2,4,6-trinitrotoluene (TNT), pentaerythol tetranitrate (PETN) and trinitrophenyl-methylnitramine (tetryl), separated by MEKC. Two fluorophores, fluorescein and rhodamine B, were investigated. All explosives except NGU and PETN were detected but sensitivity was poor. Some of this lack in sensitivity may be associated with laser instability.
