Abstract
In a magazine (1) that has an outlet (2) at the end of a forming channel (13) for dispensing a sample which is to be analyzed for example by atomic absorption spectrometry, a pusher (3) projects from above into the pulverized sample material (5) which is in the magazine (1). A small sample quantity is pressed out of the forming channel (13) and ejected through the outlet (2) by pressing the pusher (3) into the sample material (5) so that the sample material (5) is pressed into the forming channel (13) above the outlet (2) and then a small quantity in the micro- or milligram range is ejected.
