Abstract

Solvents belong to an important group of special substances used in modern technological processes and in the operation of various types of systems, especially electronic ones. Relatively high consumption of these chemicals generates the need to monitor their quality and, above all, purity. There are many analytical methods for testing the purity of chemical compounds. However, they are usually time-consuming or expensive. The paper analyses the results of tests of the acoustoelectronic system designed to assess the quality of technical solvents. The proposed method is simple, cheap and, as it seems, very effective in assessing the quality of solvents with sufficiently high evaporation rate. The method can be also applied to fast testing of light fuels. It uses the interaction between the vibrating surface of a quartz beam and the micro-droplet of the tested solvent applied to it. The theoretical basis of system operation and preliminary measurement results are also described.
