Abstract

L'invenzione concerne un procedimento ed un dispositivo per l'iniezione a vaporizzazione senza splittaggio dei composti da analizzare, in apparecchi di analisi gascromatografica.All'interno della camera di vaporizzazione, mantenuta a temperatura elevata, viene creata una zona fredda sulla quale si condensa il campione e dalla quale vaporizza il solvente che viene scaricato all'esterno. La zona fredda è realizzata con lana di vetro o di quarzo mantenuta a bassa temperatura dalla vaporizzazione del solvente. Al termine di questa, la zona fredda si riscalda e i composti da analizzare sono inviati in colonna dal gas di trasporto.(Fig. 2).
