Abstract: A distilling apparatus includes an evaporation section which heats raw water and causes the generation of vapor from said raw water, and a hydrophobic porous film through which the thus generated vapor is filtered. Because vapor separated from the raw water is supplied to one surface of the hydrophobic porous film, the proportion of the vapor relative to the fluid supplied to that surface of the film can be increased, thereby enabling the efficient filtering of a large amount of vapor through the film. In addition, because the temperature of condensed water obtained by cooling the vapor can be kept in the vicinity of the boiling point thereof, any gases and volatile substances contained in the raw water are prevented from dissolving in the distilled water, thereby enabling the production of extremely pure distilled water.

Abstract: An impurity detector atomizes a liquid sample by injecting the sample into a chamber with a gas. In the chamber the liquid is heated, preferably by heating the gas prior to injection, to cause all the liquid to evaporate. The solid impurities contained in the liquid are thus entrained in the gas and carried to a detector region. The chamber is arranged so that all the gas and all the particles arrive at the detector region. A particle detector measures the number and size of the particles and from that measurement, the concentration of impurities in the sample can be determined. The system permits on-line operation, and produces accurate results.
