Separation device and separation method
View Patent ↗An object of the present invention is to separate a material to be separated at a low cost and constant accuracy when the material to be separated is separated from a mobile phase containing the material to be separated through the passing of the mobile phase through a stationary phase, even if the mobile phase has a large volume. A separation device characterized in that a separation column provided with a stationary phase having a volume capable of processing the entire volume of a mobile phase containing a material to be separated is provided, the separation column is replaceable, and the usage count of the stationary phase reaches a lifetime count through the processing of one batch.
1. A method of separation with a separation device comprising:
determining a number of plural columns and a total column volume to be provided in the separation device is provided in an amount satisfying the following equations:
N×T 2≥( T 1+ T 2+ T 3+ T 4+ T 5), and
Ct·Vb≤Am·Vc·R·N,
where N is a number of plural columns, T1 is an equilibrium time of the separation column, T2 is an adsorption time of the material to be separated, T3 is a washing time, T4 is an elution time of the material to be separated, T5 is a regeneration time of the separation column, Ct is a concentration of the material to be separated in the mobile phase, Vb is a volume of the mobile phase per one batch, Am is a dynamic adsorption amount of the material to be separated per unit volume of the separation column, Vc is a volume of the stationary phase per one separation column, and R is a number of reuses of one separation column, one column volume being determined as 1/R;
providing a separation device composed of N plural columns provided with a stationary phase having a total volume sized (Vc·N) to process an entire volume of a selected mobile phase Vb containing a selected material to be separated.
2. The method of claim 1 , further comprising:
providing a plurality of pipes respectively connected to each of the plural columns;
providing a plurality of switching valves respectively provided on the plurality of pipes; and
providing a computer for controlling communication between the pipes by the plurality of switching valves.
