<p>One sampler for chemical analyzers comprising: one gas-tight syringe ( 10 ) with a plunger ( 11 ) for sampling from containers ( 2 ) predetermined quantities of substances to carry out chamical analyses; one first movement unit ( 15 ) operatively linked to the plunger ( 11 ) in order to move it so as to carry out the sampling; measurement means ( 20 ) of the feeding electrical voltage and electrical current of the first movement unit ( 15 ) during the movement of the plunger ( 11 ); one logical control unit ( 21 ) operatively linked to the measurement means (20) to calculate the energy used for the plunger movement ( 11 ).</p> |
