Trends in ultrasonic-based equipment for analytical sample treatment.

The recent developments achieved in ultrasonic equipment urges the need for the revision of its applications in analytical chemistry. In the present work, the last ultrasonic devices are easily presented and their applications for sample treatment are critically discussed. Comments are given on edge areas of research, such as proteomics or polymer science, which are presently taking advantage of ultrasonic sample treatments. Future applications and trends for ultrasonic-based handling approaches are also given and commented.
