Abstract

A simple effective photoacoutic probe employing the acoustic waveguide effect in quartz substrate is described. The photoacoustic probe consists of a quartz rod to the upper end of which a PZT-5A piezoelectric ceramic disk is attached. The probe was used in the acquisition of a dye-laser-excited photoacoustic spectrum of 10-μg/ml 9,10-dimethylanthracene in ethanol at room temperature. With the probe system, the spectrum was found to be essentially identical with the corresponding spectra obtained with a standard cuvette cell/attached PZT disk and a cylindrical cell/attached PZT tube detection systems; the observed relative sensitivities were 1.6:1.0:4.4, respectively.

Photoacoustic spectra of 10-μg/ml 9,10-dimethylanthracene in ethanol at room temperature in PBD dye response region obtained with (a) the cuvette cell/attached PZT disk, (b) the cylindrical cell/attached PZT tube, and (c) the photoacoustic probe transducer systems. The sensitivity factors (given as ×6.25, ×1.00, and ×2.50) represent the amplifier gains employed (e.g., ×2.50 means the amplifier gain was 2.50 times as great as ×1.00); (d) dye-laser output energy curve. The dip at ~375 nm in (a) cannot be explained and was probably an instrumental artifact.
