Abstract
The present invention relates to an automated solution generator, such as for use in generating buffering or clinical formulations or mobile phase solutions for chromatography systems, and methods for operating the automated solution generator to accurately dispense solutions, perform dilutions and prepare solutions with reduced user intervention.
Claims19
An automated solution generator comprising:
- (a) at least one solution reservoir;
- (b) a solution vessel in fluid communication with at least one solution reservoir;
- (c) a mass balance on which the solution vessel rests;
- and
- (d) a process control system that is in communication with the mass balance to periodically receive readings of the mass of the solution vessel, the contents of the solution vessel, or the combined mass of the solution vessel and its contents,
- wherein the process control system regulates the flow into the solution vessel based upon the periodic readings communicated by the mass balance.
3 more elements
A method for making a solution comprising:
- (a) introducing at least one solution into a solution collection vessel;
- (b) regulating the total amount of solution introduced into the solution collection vessel using a process control system based on a series of mass-based calculations.
