The number of publications with this focus has to increased significantly demonstrating that microwave radiation can be used in different fields of chemistry, such as digestion and extraction procedures. Lately, new procedures for sample preparation were developed including microwave induced combustion, vapor-phase digestion, sample addition to pre-heated reagents, combination of ultraviolet radiation and on line microwave digestion. This chapter presents an overview about microwave-assisted sample preparation procedures for spectroanalysis and a discussion about how these strategies led to greener procedures.  achemistry  amicrowave radiation  aSample preparation  aSpectroanalytical1 aMENEZEZ, E.
