Detection limits of about 1 g/m2 are demonstrated for the Raman determination of two organic materials, polydimethylsiloxane and dimethyl methylphosphonate, on an aluminum surface. A fiber-optic-based system is used. A large sample area is scanned to overcome heterogeneity in sample coverage. Measurements are made without use of an internal standard. Results are reported for both a Hadamard transform technique with argon-ion laser excitation and a conventional spectrometer with diode laser excitation.

Optoacoustic measurements of NO2 excited by an Ar+ laser were performed in the presence of NO, N2, H2O, and O2 matrix gases. Identical sensitivities were measured in all matrix gases except O2 where energy transfer from NO2 to the metastable O2(1Δg) state resulted in a dramatic decrease in sensitivity.
