Abstract

ANALIZADOR AUTOMATICO PARA EL TRATAMIENTO PREVIO DE MUESTRAS LIQUIDAS. ESTE ANALIZADOR AUTOMATICO PARA EL TRATAMIENTO PREVIO DE MUESTRAS LIQUIDAS ESTA BASADO EN EL ACOPLAMIENTO DIRECTO EN LINEA DE UN MODULO DE PRETRATAMIENTO CONTINUO Y UN CROMATOGRAFO DE GASES; PARA LA ASPIRACION DIRECTA DE LA MUESTRA. SE PROPONE UNA INTERFASE (3) COMO MEDIO DE CONEXION QUE INCLUYE COMO ELEMENTOS FUNDAMENTALES: UNA COLUMNA DESECANTE (4), UNA VALVULA DE INYECCION (5) DE ALTA PRESION; UN DIVISOR DE FLUJO DEL GAS PORTADOR (12); UN CONECTOR TUBULAR (8) FINALIZADO EN UNA AGUJA HIPODERMICA, Y UN CALEFACTOR ELECTRICO (7) REGULABLE. EL MODULO DE PRETRATAMIENTO (1) SE BASA EN UNA UNIDAD DE SEPARACION QUE INCLUYE: EXTRACCION LIQUIDO-LIQUIDO, PRECIPITACION, CAMBIO JONICO Y SORCION, PARA EL ACONDICIONAMIENTO DE LAS MUESTRAS (PRECONCENTRACION, DILUCION, DERIVATIZACION, CAMBIO DE DISOLVENTE, ELIMINACION DE INTERFERENCIAS). ESTE ANALIZADOR EVITA LAS OPERACIONES PREVIAS DE PREPARACION Y ADECUACION DE LAS MUESTRAS AL SISTEMA DE DETECCION; Y PUEDE SER APLICADO A LA DETERMINACION DE: CONTAMINANTES AMBIENTALES ALIMENTICIOS, CLINICOS Y FARMACEUTICOS; COMPONENTES MAYORITARIOS Y MINORITARIOS EN ALIMENTOS Y MUESTRAS BIOLOGICAS; DROGAS EN FLUIDOS BIOLOGICOS.AUTOMATIC ANALYZER FOR PRE-TREATMENT OF LIQUID SAMPLES. THIS AUTOMATIC ANALYZER FOR PRE-TREATMENT OF LIQUID SAMPLES IS BASED ON THE DIRECT IN-LINE COUPLING OF A CONTINUOUS PRETREATMENT MODULE AND A GAS CHROMATOGRAPH; FOR THE DIRECT ASPIRATION OF THE SAMPLE. AN INTERFACE (3) IS PROPOSED AS A CONNECTION MEDIA INCLUDING AS FUNDAMENTAL ELEMENTS: A DESICCANT COLUMN (4), A HIGH PRESSURE INJECTION VALVE (5); A CARRIER GAS FLOW DIVIDER (12); A TUBULAR CONNECTOR (8) COMPLETED IN A HYPODERMIC NEEDLE, AND AN ADJUSTABLE ELECTRIC HEATER (7). THE PRETREATMENT MODULE (1) IS BASED ON A SEPARATION UNIT THAT INCLUDES: LIQUID-LIQUID EXTRACTION, PRECIPITATION, IONIC CHANGE AND SORPTION, FOR THE CONDITIONING OF THE SAMPLES (PRECONCENTRATION, DILUTION, DERIVATIZATION, CHANGE OF DISSOLUTION) . THIS ANALYZER AVOIDS THE PREVIOUS OPERATIONS OF PREPARATION AND ADAPTATION OF THE SAMPLES TO THE DETECTION SYSTEM; AND MAY BE APPLIED TO THE DETERMINATION OF: FOOD, CLINICAL AND PHARMACEUTICAL ENVIRONMENTAL POLLUTANTS; MAJORITY AND MINORITY COMPONENTS IN FOOD AND BIOLOGICAL SAMPLES; DRUGS IN BIOLOGICAL FLUIDS.
