We summarize our recent work on sonovoltammetric studies of adenine, g
uanine, thymine, cytosine and their corresponding nucleosides and nucl
eotides. Ultrasound is found to be an excellent tool to enhance the re
liability of determinations of purine and pyrimidine derivatives and c
an lead to improved analytical performance characteristics and lower d
etection limits. (C) 1997 Elsevier Science B.V.
