Abstract

APARATO DE CROMATOGRAFIA LIQUIDA DE ALTA PRESION EN CUYA COLUMNA SE CARGA UNA MEZCLA DE FLUIDOS QUE CONTIENE COMO MINIMO UN SOLUTO QUE ES REACTIVO CON LAS SUPERFICIES CROMATOGRAFICAMENTE REACTIVAS DE LA COLUMNA, Y SE INYECTAN UN NUMERO DE VOLUMENES DE DIFERENTES FLUIDOS ELUYENTES EN ESA COLUMNA. LAS INYECCIONES SE REALIZAN DE FORMA QUE SE MINIMICE LA CANTIDAD REQUERIDA DE ELUYENTE. LAS INYECCIONES CORRESPONDIENTES A UNA OPERACION SE EFECTUAN DE FORMA QUE SE ASEGURE QUE, COMO MINIMO, SE PRODUZCA EL FLUJO DE LOS LIQUIDOS ELUYENTES POR LA COLUMNA, PREFERIBLEMENTE CON UN FRENTE DE ONDA PRACTICAMENTE PLANO, A UNAS VELOCIDADES CORRESPONDIENTES A UNAS VELOCIDADES REDUCIDAS SUPERIORES A 5.000, POR EJEMPLO, Y UNOS FLUJOS SUFICIENTES PARA PROVOCAR UN FLUJO TURBULENTO EN AQUELLOS FLUIDOS, LO QUE MINIMIZA EL TIEMPO REQUERIDO PARA QUE PASE TODA LA MEZCLA Y LOS FLUIDOS ELUYENTES POR LA COLUMNA. EN OTRAS OPERACIONES, LAS INYECCIONES SE REALIZAN PRACTICAMENTE SIMULTANEAS EN PUNTOS ESPACIALMENTE SEPARADOS ADYACENTES A LA ENTRADA DE LA COLUMNA O EN SECUENCIA EN UNA UNICA LOCALIZACION ADYACENTE A LA ENTRADA DE LA COLUMNA, PERO EN TODOS LOS CASOS LOS FLUIDOS TIENDEN A VIAJAR POR LA COLUMNA A UNA VELOCIDAD DE GRUPO COMUN, COMO SI SE TRATARA DE CILINDROS DE FLUIDOS ESTRECHAMENTE AGRUPADOS.
