Abstract
Se describen sistemas y métodos para medir el pH de muestras de baja alcalinidad. La presente proporciona un conjunto de sensores que comprende una pluralidad de indicadores de pH, donde cada indicador tiene donde cada uno de dichos indicadorestiene una concentracion de indicador diferente. Se genera una funcion de calibracion aplicando el conjunto de sensores a una solucion de muestra que tiene un pH conocido de manera que la respuesta de pH de cada indicador se registran simultáneamenteversus la concentracion del indicador para cada indicador. Una vez calibrado, el conjunto de sensores se aplica a muestras de baja alcalinidad que tienen un pH desconocido. Los resultados de cada indicador de pH luego se comparan con la funcion decalibracion, y las funciones de ajuste se extrapolan para obtener el pH real de la muestra de baja alcalinidad.
