Gas chromatography retention data

Hackenberg, R., Schtitz, A., Ballschmiter, K. (2003) High-resolution gas chromatography retention data as basis for the estimation of Kow values using PCB congeners as secondary standards. Environ. Sci. Technol. 37, 2274-2279. 

In a chromatographic separation procedure the parameters of the chromatographic system (stationary phase, flow, temperature, etc.) have to be selected respectively optimized with respect to some criterion (resolution, time, etc.). In gas chromatography retention data series are published and used for the sttidy of solvent/solute interaction, prediction of the retention behaviour, activity coefficients, and other relevant information usable for optimization and classification. Several clKmometrk techniques of data anal s have been employed, e.g. PCA, numerical taxonomic methods, information theory, and j ttern recognition. 

Takagi and co-workers (1989) applied FA to gas chromatography retention data for 190 solutes measured using 21 different stationary phases. Three factors were found to be sufficient to explain about 98 per cent of the variance of the retention data physicochemical meanings to these factors were ascribed as shown below ...
