Abstract
For positioning a liquid sample which is held together by surface tension to form a drop, a plurality of lances is provided that are directed onto the sample from different spatial directions. Sintered bodies are provided on the lances, from which gas escapes. The escaping gas prevents a contact between the sintered bodies and the sample. The lances are positioned so close to the sample that indentations are formed in the latter.
