Abstract

L'invenzione concerne un metodo e un dispositivo per controllare la portata di gas vettore (carrier) attraverso un apparecchio gascromatografico con colonna capillare soggetta, a variazioni di temperatura, tramite controllo della pressione di alimentazione con elaborazione computerizzata dell'equazione che regola il fenomeno. Per eliminare errori di introduzione manuale dei parametri del sistema, si prevede il calcolo di una costante rappresentante i detti parametri, effettuato rilevando tutti i valori necessari nel corso di una prova in bianco, e quindi l'utilizzazione di tale costante nell'equazione menzionata per calcolare la pressione di volta in volta richiesta per avere desiderate condizioni di portata, al variare delle altre condizioni operative del sistema.(Fig. 1).
