Remote Analysis

Results of a laboratory study for the applicability of the resonance Raman effect for remote analysis of air pollutant molecules are presented. It was found that the influence of the absorption of the exciting laser light as well as of the scattered resonance Raman light by the scattering gas can reduce the observed resonance signal to normal Raman scattering levels. The laboratory detection limit for continuum resonance Raman scattering of iodine was found to be of the order of 30 ppb.

An analytical technique for aerosol samples which utilizes the resonance Raman effect is described. The aerosol particles were generated at 50 kHz by a vibrating orifice. The nominal particle size was 45 µm in diameter. The visible lines (4579, 4765, 4880, and 5145 Å) of a continuous argon-ion laser were used as the excitation source. Within the coverage of the laser wavelengths, effects of pre-resonance, resonance, and post-resonance Raman scattering were studied. Under the resonance condition, the enhancement of p-nitrosodimethylaniline is 5.5 × 104 when compared to that of nitrate ions. The corresponding concentration of detection limit is 10−6 molar.
