Residual Contaminant Analysis with Ultrasound
For residual contaminant analysis particles must be removed from the test item before the actual analysis is carried out. Ultrasound with its predefined parameters is a suitable and cost-saving method for this. After removal solid contaminants can be filtered and analyzed. Soluble contaminants are concentrated by evaporation then analyzed.
The right ultrasonic equipment coupled with thought-through accessories is crucial for a successful analysis. The Elmasonic Select 120 ultrasonic cleaner available from Tovatech, along with sample suspension devices, provide an ideal method for residual contaminant analysis.
Several methods are available to protect products from recontamination. For example, parts being analyzed can be placed in glass beakers or test tubes containing a suitable solution. These are suspended in the ultrasonic cleaner solution. Ultrasound transmitted from liquid in the tank to the solution in the container acts on and removes the residual contaminants for subsequent analysis.
