PURPOSE:To prevent mixing of a contaminated material, by a method wherein a hood, into which clean nitrogen or a filtered air is brought to flow, is installed, at least a part thereof is designed to be openable, and a hot plate and a stirrer are further mounted. CONSTITUTION:A beaker 24, housing a sample solution and a magnetic rotator 23, is placed on a plate 16 after a door 13 of a hood 12 is opened, the plate 16 is heated over the rotation of a magnetic stirrer 17, and a heating is conducted by a heater over the agitation of the sample solution through the rotation of the rotator 23. A condensation is done on the sample solution through the flow of a clean nitrogen or a filtered air into the hood 12. This permits the rapid condensation of the sample solution for analysis of a very fine qantity of a component containing a nonvolatile component with a ppb or a pbt condensation, and besides enables a simultaneous and efficient condensation of a number of the sample solutions, where necessary. |
