HPLC Calculator

isocratic या ढाल तरीकों के लिए एचपीएलसी स्तंभ हस्तांतरण की स्थिति की गणना।

The HPLC Method Transfer Calculator does the following:

● 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.
