Embodiment Construction

[0017] It is to be understood that this invention is not limited to particular apparatus or methods, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in this specification and the appended claims, the singular forms "a," "an," and "the" include singular and plural referents unless the content clearly dictates otherwise.

[0018] Embodiments of gas sensors that measure the relative concentrations of two or more gases in a gas mixture are described below. It should be understood that the sensor is applicable to many applications. One specific application involves detecting the relative concentrations of hydrogen and chlorine in gas mixtures. Thus, although embodiments are described with reference to the measurement of relative concentrations of chlorine and hydrogen, sensors according to some embodiments may also be capable of measuri...

Abstract

A method for detecting a ratio of a first substance to that of a second substance in a mixture of substances, includes generating heat in a heating element; measuring a temperature proximate to the heating element; and calculating the ratio of the first substance to that of the second substance from the temperature. In some embodiments, the ratio of the concentrations of hydrogen and chlorine in a mixture of hydrogen and chlorine may be determined.

Description

technical field [0001] Some embodiments disclosed herein may relate to gas monitoring, and in particular, to methods and systems for measuring and / or monitoring relative concentrations of gas components. Background technique [0002] Many chemical processes produce various gases such as hydrogen, chlorine and oxygen. To control reactions and monitor conditions in closed systems, it is important to detect mixtures of gases. Typically, methods for detecting gas composition require the use of expensive equipment (eg, gas chromatographs). In addition, it is often necessary to obtain samples from containers containing gas mixtures. Also, some chemical reactions involving certain gases, such as hydrogen and chlorine, can be harmful if not performed in a controlled manner. [0003] Exemplary systems for determining the composition of gas mixtures are described in U.S. Patent No. 4,226,112 and U.S. Patent No. 4,891,629. These systems typically rely on the use of thermal conducti...
