Abstract
METODO Y APARATO PARA LA DETECCION DE UN GAS UTILIZANDO ESPECTROSCOPIA FOTOACUSTICA. EN UN PROCESO PARA LA DETECCION DE UN PRIMER GAS EN UNA MEZCLA DE GASES QUE CONTIENE UN SEGUNDO GAS, CUYO ESPECTRO DE ABSORCION INTERFIERE CON EL ESPECTRO DE ABSORCION DEL PRIMER GAR, SE REALIZA UNA MEDICION FOTOACUSTICA EN PRESENCIA DE UN TERCER GAS QUE, EN COMBINACION CON EL PRIMERO O EL SEGUNDO GAS, MUESTRA ENFRIAMIENTO CINETICO. DURANTE LA MEDICION, LA MEZCLA DE GASES ES INFLUENCIADA POR LA LUZ PULSATORIA DE UN LASER QUE TIENE UNA FRECUENCIA DE REPETICION CONSTANTE, EN EL QUE LA FRECUENCIA DE LA LUZ DEL LASER SE HACE VARIAR GRADUALMENTE. LA MEDICION COMPRENDE, POR LO MENOS, UNA DETECCION DE LA FASE DE LA SEÑAL FOTOACUSTICA EN FUNCION DE LA FRECUENCIA DE LA LUZ DEL LASER. EL APARATO PARA LA REALIZACION DEL METODO, QUE INCLUYE UN LASER, MEDIOS PARA PULSAR LA LUZ DEL LASER, UNA CELDA DE MEDIDA, UN DETECTOR DE LA RADIACION QUE PASA A TRAVES DE DICHA CELDA, UN DETECTOR DE LA SEÑAL ACUSTICA PROCEDENTE DE LA CITADA CELDA Y UN CIRCUITO ELECTRONICO DE MEDICION, SE CARACTERIZA PORQUE EL CIRCUITO COMPRENDE MEDIOS DE DETECCION DE FASE DE LA SEÑAL ACUSTICA.
