T. Kaneta et al., SEPARATION OF POLYCYCLIC AROMATIC-HYDROCARBONS BY MICELLAR ELECTROKINETIC CHROMATOGRAPHY WITH LASER FLUORESCENCE DETECTION, Analytica chimica acta, 299(3), 1995, pp. 371-375
Polycyclic aromatic hydrocarbons (PAHs) were separated by micellar ele
ctrokinetic chromatography and were detected by laser fluorometry. The
PAHs with large molecular weights were separated by using dimethylfor
mamide as an organic modifier. A He-Cd laser (325 nm, 5 mW) or a blue
semiconductor laser (415 nm, 50 mu W) was used as an exciting light so
urce. The detection limit (S/N = 3) for perylene was 1.4 X 10(-7) M un
der He-Cd laser excitation or 3.4 x 10(-7) M under semiconductor laser
excitation.
