摘要

Process for boiling liquid samples down to a residual volume comprises feeding the results from a sensor for determining the position of the liquid level in a vaporizing vessel to a controller so that the vaporizing parameters control the course of the vaporizing process. An Independent claim is also included for a device for carrying out the boiling down process comprising a control device to which the measured results from a sensor (10a) are fed to control the course of vaporization. Preferred Features: The vaporizing vessel is inserted into a tempering bath (2), the vessel and bath being heated by an infra-red radiation device. The sensor is an optical sensor.
