DETERMINATION OF EXPLOSIVES RESIDUES IN SOILS BY MICELLAR ELECTROKINETIC CAPILLARY CHROMATOGRAPHY AND HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY - A COMPARATIVE-STUDY

Micellar electrokinetic capillary chromatography (MECC) is investigate d for application as a complementary technique to reversed-phase high- performance liquid chromatography (HPLC) in the analysis of explosives residues. Separation efficiency, specificity, sensitivity, reproducib ility, analysis time and calibration linearity are examined by compari ng the suitability of HPLC and MECC in parallel analyses. Authentic so il samples from a former trinitrotoluene plant are examined, and the r esults show MECC to be a useful new technique in explosive analysis, y ielding good sensitivity, high resolution and short analysis times.
