ABSTRACT:
An apparatus for evaporative concentration of a liquid sample comprises a housing including an upper chamber and a lower chamber, a concentrator flask, a reflex tube and a vortex tube. The concentrator flask includes an upper solution vessel section and a lower cold finger section, and the flask is arranged within the housing with the solution vessel section positioned in the upper chamber and the cold finger section positioned in the lower chamber. The reflex tube is arranged at the upper end of the concentrator flask. The vortex tube has a cold air outlet connected with an inlet to the lower chamber of the housing and a hot air outlet connected with an inlet to the upper chamber of the housing. The apparatus is employed to concentrate a liquid sample contained in the concentrator flask with the temperatures of the cold and hot air from the vortex tube being sufficient to induce the evaporative separation of samples.
