Sentence examples for mobile phases in from inspiring English sources

The use of supercritical fluids as mobile phases in chromatography was suggested nearly fifty years ago.

Surface excess adsorption data from the literature for water-acetonitrile mobile phases in reversed-phase chromatography using different octadecyl stationary phases are shown to be in good internal agreement.

The mass transfer rate in the stages depends on the nature of both phase and sample systems: the highest values were achieved in experiments with acetic acid by using the octane/water biphasic system, where an equilibrium concentration distribution between stationary and mobile phases in the stages was attained.

This is due to the higher diffusitivity of analytes in supercritical fluids compared to liquids (higher optimum mobile phase velocity) and to the lower viscosity of the mobile phases in SFC compared to HPLC, which results in smaller pressure drops allowing the use of longer columns and/or columns packed with smaller particles at higher velocities.

In order to develop coated type CSPs with excellent enantioseparation capability and high tolerance against mobile phases, in this work, a series of chitosan bis 3,5-dimethylphenylcarbamate - alkyl urea)s were synthesized, which were coated on 3-aminopropyl silica gel to afford new CSPs.

The partition coefficient (K) values of the target compounds and resolutions of peak profiles were employed as the research indicators, and exponential function and binomial formulas were used to optimizing the solvent systems and flow rates of the mobile phases in a three-stage separation.

A transformation of the interaction level of a solute into its retention factor or mobility factor (a fraction of a solute in a mobile phase in relation to the total amount of the solute) and vice versa is also described.

Four solvents, CB, ODCB, CDS, and toluene, were used as the mobile phase in this method.

Water and acetonitrile were selected as the mobile phase in this work.

Both methods use a dispersion model to describe transport in the mobile phase in the column.

The high compressibility of the mobile phase in SFC however makes this problematic.
