ABSTRACT:
An electropneumatic apparatus for sampling rapidly predetermined volumes of a mixture, to be connected to a computer. It comprises an injector provided with a detector connected to the computer for indicating activation of the injector; a reactor having a chamber provided with at least one aperture, the chamber being provided in its superior portion with an air inlet/outlet connected to a pressurized air system, the chamber having a bottom outlet provided with a flow sensor connected to the computer for indicating a volume of fluid exiting from the bottom outlet; the pressurized air system having an air channel provided with a first portion connected to an air source, and a second portion connected to the air inlet/outlet of the chamber, the air channel being provided with an air controlling device connected to the computer for producing a succession of positive and negative pressures inside the chamber, whereby the predetermined volumes of the mixture can be sampled from the bottom outlet under control of the computer; and a receiving system comprising a mobile manifold array for receiving successive samples exiting from the bottom outlet of the chamber.
