Scope of the book, and acknowledgements.- The articles are focused on
'real problems' in body-fluid analysis, typically with a final
chromatographic separation of g or often ng amounts if the aim is
quantitation. The pitfalls may not be realized by a typical chemist (cf.
remarks in #A-3), but he may excel in metabolite iden- tification -
which this book covers to a fair extent. Where identity is known, and
the metabolite could interfere in therapeutic drug monitoring or in
diagnosis or itself have clinical relevance, useful guidance will come
from articles that follow. Authors have gone to much trouble, and are
not to be blamed by any reader who would have liked an introduction to
chromatography or to metabolic pathways (cf. list of conjugation
reactions at end of concluding article). Appre- ciation is also
expressed for permission to reproduce published mat- erial; the
acknowledged sources include 1. Chroma tog. (Elsevier; e. g. in #A-l),
