摘要
The invention relates to a method for solid-phase microextraction and analysis of substances in a carrier fluid, in which a collector is brought into contact with the stirred fluid containing the substances for a sufficient time and is then subjected to a solid-phase extraction directed at at least one substance adhering to the collector, and desorbed substances are transported for analysis by means of a carrier gas, in which the carrier fluid containing the substances is stirred in a receptacle of a magnetic stirrer (1) by means of a coated magnetic stirring element (7) as the collector, and/or the carrier fluid is made to move intimately relative to the collector by means of ultrasound, and then the stirring element (7) is placed in a solid-phase extraction device (8).
