Beschreibungen/Notizen

• Static methods of determining gas-liquid partition coefficients based on the gas chromatogrpahic measurement of the change in concentration of the compound of itnerest in one of the phases after its equilibration with the other are considered. The methods can be used for the accurate determination of very small (a few hundredths of a unit) and large (a few thousand units) partition coefficients in dilute solutions of almost all volatile compounds. The proposed methods make use of thermostatted variable-volume vessels (glass syringes) and reduce the errors associated with adsorption on the vessel walls and injection of the liquids under study into the chromatographic column.
