A Direct Measurement of the C<sub>2</sub>H<sub>2</sub> Concentration from the C<sub>2</sub>H<sub>2</sub>–Oil Mixed Solution Using the Photoacoustic Spectroscopy Method

The photoacoustic (PA) method is commonly used in the measurement of trace gas concentration owing to its high accuracy and reliability. However, the conventional PA method is usually used in the gas-phase environment, which leads to a long measurement time and a large equipment volume for the degas...
