Using sound waves rather than the more usual electromagnetic waves. Ultrasonic spectroscopy provides a non-destructive way to measure the properties of materials. It can also be used for monitoring the course of dynamic processes like chemical reactions. Although the ways in which the properties of ultrasonic waves change as they passed through materials were well known, the technique has only recently been able to be applied to material analysis. In the past , the sample sizes required were too large, the measuring techniques were overly complicated, and it was impossible to make measurements that were sufficiently accurate to give meaningful data. Now, Ultrasonic Scientific Ltd., has managed to overcome these difficulties, and launched the world’s first high-resolution ultrasonic spectrometer, the HR-US 101.
