Abstract

In a method and apparatus for the analytical determination of trace compounds, portions of a sample disposed on a sample carrier are irradiated with light having an energy density of 1 to 100 MW/cm.sup.2 so that any organic trace compounds are removed from the irradiated sample portions, the removed trace compounds are collected by a capillary which is adjustably supported so as to be movable in close proximity to the irradiated sample portion and the organic trace compounds collected by the capillary are supplied to an analysis apparatus for detection.
