描述For my past sins, Leslie Ettre has given me the privilege of writing a few words to preface his excellent little book. It gives me great pleasure to do so, because of the many years of fruitful collabo- ration we have had at Perkin-Elmer, because it is refreshing to see a treatise in gas chromatography in which the theoretical treatment has been bared to its essentials, without a mushrooming of formulae which, by means of an ever increasing number of parameters, account for more and more, and explain less and less, and because the author has recognized that the gas chromatographic column is a nearly passive element in its own right which deserves to have a treatise written nearly exclusively about it, just as electrical circuit theory can be discussed without elaborate references to vacuum tubes and meters. I wish this conscientiously written volume the success it deserves. M. J. E. GOLAY VII Preface Gas chromatography is a separation technique used primarily in analytical chemistry. Therefore, it is evident that special emphasis should be placed on that particular part of the apparatus in which the separation takes place. This part is the column, the heart of the gas chromatograph

The Gas Chromatographic System,ther components of the gas chromatograph. But, of course, columns cannot be used alone, as an independent unit. One must rely on other components for proper sample introduction, adequate heating of the column, and sensitive detection and accurate recording of the separated peaks. In other words, the

Introduction, chromatography are the result of such considerations. Martin and Synge, in 1941, in describing the method of liquid-liquid partition chromatography’ predicted the possibility of substituting gas for liquid as the mobile phase; similarly, open tubular columns are the result of Golay’s theoretical consideration of the behavior of packed columns.
