PREFACE
This volume is ba.sed on the presentations gi ven at the ElectroFinnAnalysis conference held
on
June 6-9, 1988 in Turku-Äbo, Finland. This event was the second in a series of electroanalytical
conferences. The first was held in Ireland 1986 and the next will be held in Spain 1990. The aim of these conferences is tobring tagether scientists who use electroanalytical methods in their research. This is also reflected in the disposition of this volume where instrumentation and applications from the different fields have their own chapters. The editors are grateful to Mr. Johan Nyman, Mr. Kent Westerbolm and Mr. Markku Lehto for their technical assistance during the editorial work of this volume. Ari Ivaska Andrzej Lewenstam Ralf Sara
