Fluorescent Detection and Spectrophotofluorometric Characterization and Estimation of Carbazoles and Polynuclear Carbazoles Separated by Thin Layer Chromatography.

Chromatographic isolation and spectral analysis of polycyclic quinones. Application to air pollution analysis

“…Parent polycyclic arenes were separated on aluminum oxide thinlayer plates with hexane:ether (19:1, v/v) as the developing phase. Benzanthrone (7H-benz[de]anthracen-7-one) was resolved on aluminum oxide thin-layer plates using pen-tane:chloroform (3:2, v/v) as the mobile phase (18). All thin-layer chromatography was carried out in sandwich chambers (19) (Brinkmann, Model 116C).…”

Isolation and Identification of Nitrogen Compounds in Petroleum.

“…Since the introduction of the electron capture detector by Lovelock and Zlatkis (6), its possibilities have been used (1,4,5) in spite of the lack of reliable response and difficulty in avoiding unknown interferences.…”

Air Pollution

“…Thin-layer chromatography can be used for the separation of these types of compounds (230, 233, 24O). Spectrophotofluorometry and spectrophosphorimetry have been used in the subsequent analyses (25,26,232). Quenchofluorometric methods allow the characterization and analysis of aza heterocyclics, polynuclear amines, imino heterocyclics, or polynuclear hydrocarbons in the presence of the other classes of compounds (237).…”
