Abstract:

It is rather trouble for the treatment of sediment before determination. Slurry sampling with ultrasonic agitation combines the advantage of both solid and liquid sampling permitting samples to be introduced easily and reproducibly into the furnace utilizing conventional pipetting technology and minimizing sample preparation time. Ultrasonic agitation has the added benefit of aiding in the extraction of many of the metals into the liquid phase of the slurry.
