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-microg/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.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
