Abstract

Se proporciona una celda de muestra para análisis espectrofotométrico IR de una muestra líquida. La celda de muestra comprende dos placas transparentes substancialmente paralelas que abarcan una cavidad para retener la muestra líquida, y un circuito de control de temperatura para controlar una temperatura de la muestra líquida en la cavidad. El circuito de control de temperatura comprende al menos un sensor de temperatura para medir una temperatura en o cerca de la cavidad, al menos un elemento de calentamiento para aumentar una temperatura de la muestra líquida, y medios de control, acoplados al sensor de temperatura y al elemento de calentamiento para controlar el elemento de calentamiento en dependencia de la temperatura en o cerca de la cavidad. El elemento de calentamiento comprende al menos una lámina de calentamiento que está fijada a o térmicamente acoplada a la primera de las placas transparentes de tal forma para permitir que un haz de luz IR pase a través de las placas transparentes y la cavidad sin obstaculizarse por la lámina de calentamiento.
