Porous polymers coated with stationary phases. Contribution of the support to retention behaviour in gas chromatography. Chromosorb 102 coated with ethofat 60/25, squalane and fractonitril VI. Calculation of the experimental partition constants

Following previous work on the solute-stationary phase-adsorbent interaction phenomena associated with the use of Chromosorb 101 support in gas chromatography, the retention of different polarity compounds on columns of Ethofat, squalane and Fractonitril VI on Chromosorb 102 has been studied. The experimental partition coefficients in these three liquid phases have been compared with those ones obtained earlier on Chromosorb 101 and Chromosorb P. The values have been related to the geometry of the support surface and the different coating of the liquid phases by scanning electron microscopy.
