Die neuartigen polarographischen Methoden, ihr Prinzip md

Principles and Scope) by Helmut Schmidt and M. v. Stackelberg. Monographs to “Angewandte Chemie” and “ChemieIngenieur-Technik”, No. 77. Verlag Chemie G.m.b.H.,

Polarographic techniques have developed so much during the
forty years since theinvention ofpolarography that many new
developments have escaped the notice not only of workers
outside the field of polarography, but also of those who are
concerned exclusively with so-called “classical” direct current
polarography. Progress in polarographic .techniques is not
reported, however, in any of the existing tex! books onpolarography. It is therefore to be welcomed that the author of one
of the best text books on polarography, in collaboration with
another author, has undertaken this task. This book provides
chapters on stationary methods (classical, differential, derivative, and key polarography), on non-stationary methods
(oscillographic methods and methods with superimposed
alternating component, i.e. also square wave and pulse polarography), and constant current methods.
The most important merit of this book, in the reviewer’s
opinion, lies in its excellent style, which does not get lost in
technical and constructional details but which decsribes the
principles of the method, the basic circuit, and the original
purpose of this technique or that apparatus. It can bc said that
this is one of the most useful text-books on polarography that
have been published during the past few years. It ought to be
translated into a language that would enable it to be read outside Central Europe.

This two-volume work, constituting volumes I1 and 111 in
the series “Monographies de Chimie Organique” (supplementary to the well-known “Trait6 de Chimie Organique”) is the
first largesale manual dealing with chromatographic
procedures suitable for separation of organic compounds. The
editor, E. Lederer, has been a leading contributor to the
development of chromatography since its rediscovery and is
co-author, with M . Lederer, of the well-known monograph
“Chromatography” [21.

thirty-two contributions. l h e directions to authors for the
style of their contributions were: 1. All reliable procedures
to be described in such dotail that they can be followed
without reference to the original literature. 2. All other
procedures to be cited briefly. 3. In the discussion of different
procedures and their applications, always follow the order:
adsorption, ion-exchange, partition, and at the same time
always discusscolumn- and paperchromatography separately.
The fact that the 32 contributions have made a unified whole
can be ascribed to the strict adherence to these guiding
directions and the use throughout of precise and concise
writing.
The work is divided.into three parts. Part I (Volume I)
contains four chapters on the theory and general basis of the
various techniques of adsorption, ion-exchange, partition,
and gasthromatography. The concluding chapter covers the
use of radio-isotopic techniques in chromatographic separations.
Part 11 (Volume 1) covers applications of the various chromatographic techniques to organic chemistry and is divided
according to classes of conipounds (carbohydrates, alcohols,
acids, amines, alkaloids, c9tc.). This part concludes with a n
outstanding contribution on the separation of stereoisomers
(geometric isomers, diastereoisomers, resolution of racemates).
Volume I1 contains the third and largest part (Part III), on
the chromatography of naturally occurring compounds.
Here, also, the material is divided according to the class of
substance (sugars, amino acids, peptides, steroids, vitamins,
hormones, antibiotics, etc.). Not only the chemist, but also
the biologist, the microbiologist, and the physiologist can
draw rich profit from thu material presented here. It is
regrettable that so brief reference is made to thin-layer
chromatography, which has recently found more and more
frequent application.. It receives only a single mention. The
reason may be that its importance was not so well recognized
at the time of the literature deadline for the work - the
first volume appeared in 1959 - as it is today.
Mowthan in other separation techniques, success in chromatography depends on the details of the procedure, i.e. the type
and activity of the adsorbent., the type of ion-exchange resin,
the eluting capacity of the solvents, and the partition coefficient of the solvent system used must be optimal for the
particular separation problem. Hence there are innumerable
data in the literature on new and novel variations of experimantal conditions, and it is a wearisome task to select the
best for any particular case. The great merit of E. Lederer’s
handbook is that this task will henceforth be much lighter,
now that specialists have gathered and critically examined the
vast amount of original material and have so presented proved methods that it is possible to work without
reference to the original litmature. As an excellent collection,
with numerous illustrations, tables of RF values, details of
solvent systems, and reagents for the detection of colorless
compounds, together with more than 6200 literature references, these volumes will quickly become an indispensible
guide in all chromatographic work, even for those little
acquainted with the French language.
