Abstract
The most time consuming steps in an analytical chemistry laboratory involve sample preparation and analyte drying. Sample preparation involves the extraction of an analyte typically using acid digestion and heat. Analyte drying usually involves using heat to bring sintered glass crucibles to constant mass before and after precipitate collection. In this research, gravimetric analyis and a conventional microwave oven were used to moniter the amount of time for each of these steps. The time in the digestion step was minimized by using perfluoroalkoxy alkane polymer (PFA) vessels which were ideal since they are microwavable, acid resistant, and able to withstand moderate pressures. Drying time was decreased by using a convential microwave oven instead of the typical drying oven which reduced the drying time from hours to minutes. This presentation will show the advantages of utilizing conventional microwave oven technology to increase the efficiency of the analyitical process.
