Abstract: A system, module and method for continuous countercurrent spiral chromatography are disclosed. The module includes an input port for receiving an input solution, a first mixer for mixing the input solution with a recycled solution to produce a first mixed output, a stage I separator for concentrating the first mixed output to produce a stage I solid fraction, a second mixer for mixing the stage I solid fraction from the stage I separator and an optional buffer solution to produce a second mixed output, and a stage II separator for concentrating the second mixed output to produce a stage II solid fraction which exits the module. At least one separator is a spiral separator. The system includes a plurality of modules, and at least one of the plurality of modules includes a spiral separator. The method includes purifying an unpurified solution with the plurality of modules.
