HPLC Calculator 1.0

● Calculates conditions for transfer of an isocratic or gradient method from one HPLC column to another.
● Recommends flow rates for analytical columns.
● Allows method scaling from microbore through preparative column range based on the 2 sets of column variables (column length, column I.D., particle size) and current method conditions (flow rate, injection volume, pressure, run time, equilibration time).
● Calculates time and solvent saved, if any.
● Supports Ascentis® Express and other common particle sizes.
● Predicts the gradient delay that must be applied when transferring a gradient method, based on the user entered value of dwell volume.
