Abstract

Un'analisi GC capillare con iniezione a vaporizzazione del campione viene effettuata iniettando il campione in un iniettore riscaldato ad una temperatura almeno pari a quella di ebollizione del composto più altobollente, programmando una velocità di iniezione variabile compresa nell'intervallo tra 1 ?l/s e 100 ?l/s ed effettuando l'iniezione del campione alla velocità programmata (fig. 4).
