Determination of a toxic agent in feed by gas chromatography

This is a representative example [16] of those determinations in wich sample pretreatment is essential to the analytical procedure and where robotlza- 

The operational sequence performed by this workstation involves a number of steps, namely  

The data supplied by the Instrument are transmitted to the microprocessor, which, on the basis of the Initial sample weight introduced by the operator, provides the content or concentration of the toxic agent In the feed sample. 

The use of the robot In this determination Involves two drawbacks, namely
