Abstract

Un procedimento per la preparazione di campioni liquidi per un'analisi prevede di alimentare un campione da riconcentrare ad un contenitore-evaporatore provvisto di mezzi per controllare la temperatura e la pressione al suo interno e contenente uno o più materiali di supporto, evaporare il solvente per riconcentrare il campione al volume richiesto ed inviare il campione riconcentrato ad un apparecchio di analisi. (Fig. 4)
