Programmable automatic means for the deposition in a precise position of a minute, precise quantity of liquid on an analytical support

摘要

Programmable automatic means for the depositing in a precise position on an analytical support of a precise, minute liquid quantity. It comprises a main support provided with displacement means, a piston syringe mounted on the main support, a distributor of a plurality of hollow sampling needles, a cutting device, a sample solution distributor with several recesses, an analytical support holder, an analytical support gripping means and extraction means, a distributor for new analytical supports, a receiver for analytical supports following the sample deposition and a used needle extractor.PPThis automatic means can be used in a system associated with a thermoionization mass spectrometry analysis apparatus.
