摘要

The device of the invention comprises; a contact column 1 A in which a testliquidflows from top to bottom and a vapor flows from bottom to top, a rotary shaft9 which isinserted vertically in the contact column 1 A, rotors 10 which are provided atdifferentheights on the shaft, and which convert the test liquid into a thin film bycentrifugal forceand then discharge the test liquid from the outer periphery thereof, and trays20 whichreceive the test liquid discharged from an upper rotor and guide the testliquid to the centerof a lower rotor. The rotors 10 have furrows 13, which the test liquid flowsover when thefilmy test liquid flows out from the center of the rotor towards the outerperiphery.
