Summary

The mass spectrometric tracer pulse (MSTP) chromatography method was used to measure the amount of supercritical n-pentane dissolved or adsorbed into SE-54 and SE-30 capillary columns. Partition data were measured above the critical point of n-pentane at temperatures from 200 ° to 300 °C and pressures between 35.04 and 54.42 atm. The data obtained provide evidence for mobile fluid solubility or adsorption into the stationary phase under the conditions of supercritical fluid chromatography (SFC). At 220 °C, solubility and/or adsorption of supercritical n-pentane decreases by increasing the pressure and reaches a minimum at approximately 45.00 atm. The effect of mobile-fluid pressure on its solubility or adsorption becomes limited at temperatures over 260 °C. This study demonstrates the unique experimental capabilities of the MSTPC method for quantitative measurement of the physico-chemical interaction of the complex multicomponent system encountered in SFC which is not possible by any other technique. An innovative instrumental design for modification of GC/MS systems for SFC, GC/MS operation is also described.
