PURIFICATION OF SAMPLES BY INTERPHASE MASS TRANSFER USING MICROPOROUS HOLLOW-FIBER MEMBRANES ABSTRACT OF THE DISCLOSURE Method and apparatus are provided for accomplishing improved separation and purification of an analyte by mass transfer between immiscible phases employing microporous hollow-fiber membranes. The invention eliminates several problems of the prior art. A number of possible modes of separation by mass transfer are possible according to the invention, including liquid-liquid extraction, back extraction, simultaneous forward and back extraction, gas absorption into a liquid, gas stripping from a liquid and simultaneous gas absorption and stripping.
