In a paper published in 1992 [K.S. Reddy, J.-Cl. Dutoit, E.sz. Kovats, Pair-wise interactions by gas chromatography. I. Interaction free enthalpies of solutes with non-associated primary alcohol groups, J. Chromatogr. 609 (1992) 229] retention indice

Gas–liquid distribution coefficients at ideal dilution in non-volatile solvents can be measured by gas chromatography. The numerical value of a coefficient depends on the choice of the concentration unit in the solvent and in the gas phase. The rel

Kovats’ retention indices were determined for 41 halogenated compounds by gas–liquid chromatography (GLC) at temperatures from 373 to 433 K using fused silica open tubular capillary columns coated with 19,24-dioctadecyldotetracontane (C78H158, C7

A polar type liquid having a secondary alcohol substituent on a branched alkane skeleton, SOH, was used as stationary phase. The molecules of this stationary phase are nearly isomorphous and isochor with those of the branched alkane, C 78 , elected a

The retention of 39 molecular probes was measured on chemically bonded dense layers of (3,3-dimethylbutyl)dimethylsiloxy (DMB) and tetradecyldimethylsiloxy (C 14 ) substituents on silica as a function of the composition of the binary acetonitrile-wat

The adsorbents studied were samples of a precipitated silica, covered with a dense layer of (3,3-dimethylbutyl)dimethylsiloxy-, (5-cyano-3,3-dimethylpentyl)-dimethylsiloxy-and tetradecyldimethylsiloxy-substituents. Deuteration of unreacted silanols a

Mixed chemically bonded monolayers of organosiloxy substituents were prepared by treating surface hydrated silicon dioxide samples with mixtures of R (1) R (2) R (3) -(dimethylamino)-silanes in boiling cyclohexane (R is for an organic radical). Isoth

It is shown that retention volumes can be calculated in terms of the total material content in the chromatographic column as transported by the eluent, termed the “column capacity”. With the aid of this retention equation, of general validity, th
