Изобретение относитс к устройствам дл анализа веществ путем измерени выделившегос газа в изобарических услови х, например в кулонометрах.The invention relates to a device for analyzing substances by measuring the released gas in isobaric conditions, for example, in coulometers.
Известны устройства подобного типа , в частности водородно-кислородные кулонометры.Known devices of this type, in particular hydrogen-oxygen coulometers.
в известном устройстве разло)чение воды происходит в электролизере, представл ющем собой стекл нную трубку, один конец которой закрыт краном, с другой - соединен каучуковой трубкой с измерительной бюреткой. В нижйюю часть электролизера впа ны две пла-тиновые пластинки площадью около 2см 5 кажда . Электролизер помещают в стекл нную рубашку, заполненную водой, температура которой во врем работы поддерживаетс посто нной. Объем электролизера можно мен ть в зависи- 20 мости от измер емых количеств электричества . Количество прошедшего электричества измер ют по объему выделившегос газа (смеси водорода и кислорода) который наход т по объему элeктpoлитa 5 вытесненного газовой смесью из элек-тролизера в бюретку.In a known device, water is decomposed in an electrolytic cell, which is a glass tube, one end of which is closed by a tap, the other is connected by a rubber tube to a measuring burette. Two platinum plates with an area of about 2 cm 5 each fall into the lower part of the electrolyzer. The cell is placed in a glass jacket filled with water, the temperature of which is kept constant during operation. The volume of the cell can be varied depending on the measured quantities of electricity. The amount of transmitted electricity is measured by the volume of gas released (mixture of hydrogen and oxygen) which is found by volume of electrolyte 5 displaced by the gas mixture from the electrolyzer to the burette.
Бюретку устанавливают вертикально в держателе таким образом, чтобы ее можно было перемещать вверх и вниз 30The burette is installed vertically in the holder so that it can be moved up and down 30
дл доведени жидкости в электролизере и бюретке до одинакового уровн flj .to bring the liquid in the electrolyzer and burette to the same level flj.
Кулонометр не позвол ет точно измерить малые объемы газа, а следовательно , и малые количества пропущенного электричества.The coulometer does not accurately measure small volumes of gas, and consequently, small amounts of missing electricity.
Анализ проводитс при повышенном давлении газа над электролитом, который до начала анализа насыщают выдел ющимс водородом и кислородом при атмосферном давлении. Следовательно, часть выделивидегос газа растворитс дополнительно в электролите и при окончательном измерении потребуетс некоторое врем дл восстановлени степени насыщени раствора газом, соответствующей атмосферному давлению.The analysis is carried out at an increased gas pressure over the electrolyte, which, prior to the analysis, is saturated with evolving hydrogen and oxygen at atmospheric pressure. Consequently, part of the evolution gas is additionally dissolved in the electrolyte and during the final measurement it will take some time to restore the degree of saturation of the solution with gas corresponding to atmospheric pressure.
Известно устройство дл анализа веществ путем измерени количества выделившегос газа в изобарических услови х, содержащее нуль-прибор, выполненный в виде индикатора давлени , подсоединенный к реакционной емкости, а также измерительную бюретку 2,A device for analyzing substances is known by measuring the amount of evolved gas under isobaric conditions, containing a null device made in the form of a pressure indicator connected to the reaction vessel, as well as a measuring burette 2,
