Abstract

SISTEMA PARA SERVIR CANTIDADES MEDIDAS DE LIQUIDO, TALES COMO REAGENTES UTILIZADOS EN CROMATOGRAFIA. EL LIQUIDO SE MUEVE PRIMERO A PRESION DE GAS DESDE UN RECEPTACULO (1), COMO UNA BOTELLA DE REAGENTE, A TRAVES DE UNA VALVULA (6) ADENTRO DE UN TUBO ESTRECHO (2). ALCANZA UN DETECTOR (7) QUE, AL DETECTAR SU PRESENCIA, CIERRA LA VALVULA (6) ATRAPANDO ASI UNA CANTIDAD DE LIQUIDO ENTRE LA VALVULA (6) Y EL DETECTOR (7), CONSTITUYENDO ESTA CANTIDAD DE LIQUIDO ENTONCES UNA "UNIDAD" O "PULSO" DE LIQUIDO. EL MOVIMIENTO DE LA VALVULA (6) SE UTILIZA PARA CONECTAR UN SUMINISTRO DE GAS QUE CONDUCE LA "UNIDAD" O "PULSO" FUERA DEL TUBO A UN DESTINO FINAL, COMO UNA COLUMNA CROMATOGRAFICA. LUEGO SE PUEDE TRASLADAR OTRA "UNIDAD" O "PULSO" DENTRO DEL TUBO (2) Y ESTO SE PUEDE REPETIR DE MANERA QUE LA ENTREGA AL DESTINO SE EFECTUE EN UNA SERIE DE TALES "UNIDADES" O "PULSOS". AL CRONOMETRAR LA ENTREGA DE UNA "UNIDAD" O "PULSO", SE PUEDE SERVIR UNA CANTIDAD MENOR QUE UNA "UNIDAD" O "PULSO" PASANDO LIQUIDO AL TUBO(2) DURANTE MENOS TIEMPO QUE EL NECESARIO PARA SERVIR UNA "UNIDAD". ESTO SE PUEDE UTILIZAR PARA ELABORAR UNA ENTREGA QUE NO SEA UN MULTIPLO UNITARIO DE UNA "UNIDAD" O PARA SERVIR UNA PEQUEÑA CANTIDAD MENOR QUE UNA "UNIDAD". HAY INVOLUCRADAS PARTES SIN MOVIMIENTO Y SE CONSIGUE UNA ENTREGA DE CANTIDADES MEDIDAS CON PRECISION.
