Description
Изобретение относитс к области газового анализа и может быть использовано дл определени микроконцентрации газообразных веществ , вступающих во взаимодействие с кислородом при температуре 400-1000°С (восстановителей ), например, водорода, метана, СО, углеводородов и других органических веществ в инертных по отношению к кислороду средах, например инертных газах, азоте.The invention relates to the field of gas analysis and can be used to determine the microconcentration of gaseous substances that interact with oxygen at a temperature of 400-1000 ° C (reducing agents), for example, hydrogen, methane, CO, hydrocarbons and other organic substances inert to oxygen environments, such as inert gases, nitrogen.
Известен способ измерени концентрации восстановителей с помощью устройства, включающего твердоэлектролитную электрохимическую чейку (ТЭЯ), обладающую кислородоионной проводимостью. В основе этого способа лежит свойство ТЭЯ с высокой степенью точности регистрировать наличие избыточного кислорода или избыточного восстановител в анализируемом газе по резкому изменению э. д. с. на ее электродах.There is a method for measuring the concentration of reducing agents using a device comprising a solid electrolyte electrochemical cell (SED) with oxygen-ionic conductivity. The basis of this method is the property of the SEM with a high degree of accuracy to detect the presence of excess oxygen or excess reducing agent in the analyzed gas by a sharp change in e. d. on her electrodes.
Недостатком этого способа вл етс сложкость автоматического анализа, дл осуществлени которого необходимо специальное устройство , автоматически регулирующее количество добавл емого кислорода в зависимости от э. д. с. чейки.The disadvantage of this method is the complexity of the automatic analysis, which requires a special device that automatically adjusts the amount of added oxygen depending on e. d. cells
Цель изобретени - иовыщение точности измерени и упрощение аппаратурного оформлени .The purpose of the invention is to improve the measurement accuracy and simplify the hardware design.
Отличительной особенностью предлагаемого способа вл етс то, что на электродах A distinctive feature of the proposed method is that on the electrodes
