Abstract

SISTEMA DE INTERCAMBIO DE DISOLVENTE Y CONCENTRADOR DE MUESTRAS. SE PREVE UNA VARILLA DE GUIA (1) EN TORNO A LA CUAL FLUYE UNA SOLUCION, DISPUESTA EN UNA CAMARA (2). UNA FUENTE DE CALOR (3) RODEA LA VARILLA DE GUIA. LA SOLUCION, DE PREFERENCIA, SE MEZCLA CON UN DISOLVENTE DE INTERCAMBIO, TENIENDO EL DISOLVENTE DE INTERCAMBIO UN PUNTO DE EBULLICION MAS ALTO QUE EL DE LOS DISOLVENTES DE LA SOLUCION. AL FLUIR LA MEZCLA BAJANDO POR LA VARILLA DE GUIA, LOS DISOLVENTES DE ORIGEN SON PREFERIBLEMENTE EVAPORADOS, CONCENTRANDOSE LOS MATERIALES DE INTERES Y QUEDANDO EL EFLUENTE RELATIVAMENTE MAS CONCENTRADO EN EL DISOLVENTE DE INTERCAMBIO.
