Abstract
In this paper, we report the development and use of a photoacoustic cell designed for gas spectroscopy of volatile organic compounds (VOCs) used as biomarkers of breast cancer. The cell, composed of a PMMA Helmholtz resonator grafted to a finite size tube. A commercial microphone mounted on the Helmholtz enables the measurement of the system response at its resonance frequency. The system was successfully characterized using different concentrations of isopropanol (0.5 to 17 ppm) using tunable MIRCAT QCL laser with wavelength range of 8-11μm.
