Apparatus for automatically taking and analyzing samples of substances made available in random manner, is of the type comprising an analysis assembly including at least two analysis stations having different characteristics, and a module delimiting temporary storage slots for receptacles containing different substances to be analyzed by different methods applicable to each of said substances, said apparatus comprising: receptacles each bearing a code identifying the substance contained therein, the analysis treatment to which is is to be subjected, and a treatment priority attributed thereto; means for detecting the in-use or available status of each analysis station; means for scanning the slots in the storage module for reading the codes of the receptacles and for storing them in priority order in conjuction with the characteristics of the corresponding treatment and the addresses of the slots; means for seeking in priority order correspondence between the treatments to be performed and a currently available compatible analysis station; means for displacing an insertion system into relationship with the available analysis station; means for bringing the selected sample receptacle into relationship with an extraction station; means for extracting at least a portion of the sample from the selected receptacle and for transferring it into the insertion system; means for inserting the sample into the analysis station; means for controlling the operating conditions of the analysis station as a function of the analysis treatment to be performed; and means for returning the insertion system to its home position in readiness for a new operating cycle.

Apparatus for automatically taking and analyzing samples of substances

The present invention relates to an apparatus for the mineralization of compounds which includes a micro-wave heating chamber which receives the sample containing portion of a sample container and has a stack which surrounds the upper portion of the sample container which extends out of the micro-wave heating chamber. The apparatus further includes a transporting system which supplies the sample containers to the micro-wave heating chamber in individual, automatic and random succession.

Mineralization apparatus for the individual, automatic, treatment of

The present invention relates to an apparatus for the chemical reaction of compounds, wherein said apparatus comprises: sample container means having an enlarged sample containing portion at a lower end thereof and an upwardly extending neck portion, a housing defining a microwave heating chamber having an upper wall and defining in said upper wall an opening and a stack bordering said opening and rising to a height forming an absorption barrier to micro-waves. The invention is more particularly applicable to a reaction of mineralization.
