Foreword
It is an excellent move that you look into this book!
Analytical chemists want to be efficient and rapid: we are interested in a given task and
the results should be available the next morning. This suggests taking the simplest route:
“inject and see”, there is no time to fiddle about technology! The vendor of the possibly expensive
instrumentation might have highlighted the simplicity of his apparatus.
This is a fundamental error. Efficient analysis presupposes a significant amount of time
being devoted to understanding the method and the instrumentation. Not doing this in the
beginning all too often exacts a high price at a later stage, e.g. in terms of a laborious and
awkward method, endless troubleshooting and poor results.
Knowledge of the technology is a prerequisite to make the best choices for a straight and
simple method – from sample preparation to injection, chromatographic resolution and detection.
If we are honest, we know that a staggering amount of our time is lost to troubleshooting,
and unless we have a deep insight into the technology, this troubleshooting is
likely to be frustrating and ineffective (problems tend to recur). Hence investing time into
understanding the technology is a wise investment for rapid (and reliable) analysis.
Additionally, efficient analysts devote a substantial part of their time to keeping up with
technology in order to keep their horizons open: we cannot always anticipate what might
be useful tomorrow, and a brilliant alternative may not come to mind if one were not acquainted
with the possibility beforehand. To investigate technology only in the context of a
given, possibly urgent task is shortsighted. Admittedly, it takes discipline to absorb technical
information when the current necessity may not be immediately apparent. However, it pays
back many times. It may also be difficult to convince a boss that the investment into reading
basic texts and experimenting with puzzling phenomena is essential to be an efficient analyst
– unless he was an analyst himself and knows firsthand the demanding nature of analytical
chemistry!
It is great that an old hand in the field like Hans-Joachim Hübschmann took his time to
bring the present knowledge into such a concise and readable form.
