This comprehensive reference and handbook covers all aspects of ultrasound for analytical applications. Besides classical extraction techniques, it also provides an overview of ultrasound applications and devotes two chapters to proteomics and polymer technology. From the contents: Common ultrasonic devices. Elemental speciation. On-line applications. Accelerated extraction of semivolatile and volatile organics. Extracting reagent. The ultrasonic bath vs. the ultrasonic probe. Liquid-liquid extraction. Liquid-solid extraction. Solid-liquid extraction. Solid-phase extraction. Solid-phase microextraction. Stir bar sorptive extraction. Of great interest to researchers in academia and industry, as well as analytical and natural products chemists, and those working in trace analysis.
