In analytical chemistry the majority of effort has historically been placed on
the lowering of detection limits and widening linear dynamic ranges.
So why worry about sample preparation? Here are some good reasons...

Traditional methods of sample preparation, e.g. hotplates, are responsible for a large
amount of the irreproducibility. The use of microwave irradiation rather than
convection and/or conduction heating reduces errors in the sample preparation process.
The use of microwaves also addresses the other problems of time of analysis and sample contamination.
