ABSTRACT:
Micro-distillation apparatus is provided for analyzing acidic anions in which the acidic anion sample is placed in a lower elongated member in water containing an acidifying material, upon heating the acidic anion leaves the lower member as a gas, passing through a permeable membrane into an upper elongated member containing a material which converts the acidic anion to a salt and the salt is recovered for analysis. The micro-distillation apparatus is sized so that a number of samples can be heated in a small heating member, such as a hot block heater.
