The first part of the book introduces the reader to the basics concepts of GC, as well as the key properties of GC columns. The second part describes the mathematical and physical background of GC. In the third part, different aspects in the formation of a chromatogram are discussed, including retention times, peak spacing and peak widths. An invaluable reference for any chromatographer and analytical chemist, it provides all the answers to questions like:* At what temperat 606 $aGas chromatography 606 $aChromatographic analysis 608 $aElectronic books. 615 0$aGas chromatography. 615 0$aChromatographic analysis. 676 $a543.85 700 $aBlumberg$b Leonid M$0875557 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910139422803321 996 $aTemperature-programmed gas chromatography$91954880 997 $aUNINA
