Description
Существзющие стекл нные электроды дл измерени рН р;;створо:5 обладают тем недостатком, что при работе е ними обьем жидкости быть не :менее 10 мл.Existing glass electrodes for measuring the pH of the p ;; valve: 5 have the disadvantage that when operated with them, the volume of the liquid should not be less than 10 ml.
Предметом изобретени вл етс стекл нньи электрод, лосредСТ1ЮМ которого 1Можно производить измерени рН в капле жидкости.The subject of the invention is a glass electrode, the lagging index of which 1 It is possible to measure pH in a drop of liquid.
Отличительна особенность описываемого электрода состоит LS том, что он представл ет собой изогнутую стекл нную трубку, заполн емую серной кислотой и заканчивающуюс пленкой из электропроводного стекла , на поверхность которой нанос т исследуемую Ж11дкость.A distinctive feature of the described electrode is the LS that it is a curved glass tube filled with sulfuric acid and terminated with a film of electrically conductive glass on the surface of which the material under study is applied.
Стекл нный электрод состоит из изогнуто трубки / (сл. чертеж) неэлектропроводного стекла, заиолн емо кислотой. Трубка / с одной стороны заканчиваетс шлифом .2, суда вставл етс остек.тениый 1латнновый электрод 5, имеющий электрический чонтак с потен 1,юметром через проводник 4; на противоположном конце трубка заканч ваете тонкой пленкой 5 из электропроводного , приваренной к утолщенному концу трубки /.The glass electrode consists of a bent tube / (ff. Drawing) non-conducting glass filled with acid. The tube / on one side ends with a thin grinder .2, the vessels are inserted with a glass-coated 1-gauge electrode 5, which has an electric cable with a potential 1, and a meter through the conductor 4; at the opposite end of the tube, finish with a thin film 5 of electrically conductive, welded to the thickened end of the tube.
До наваривани электропроводной пленки 5 провер ют ее эле тропроводпость; затем прижимают к ней пакаленный на до разм гчени утолщенный конец 6 трубки /. Полнота приваривани провер етс путе.м заполнени 1водой остывшего электрода. Трубка 1 с нриваренной ней пленкой 5 фиксируетс в положении, указанном ia чертеже, пр помощи битума 7, заполн ющего чашку 8, котора вставлена в металлнческую муфту 9 щтатива.Before welding the electrically conductive film 5, it is tested for its electrical conductivity; then press the thickened end 6 of the tube to it, smoked until softened. The completeness of welding is checked by filling with 1 coolant electrode. The tube 1 with the film 5 welded by it is fixed in the position indicated in figure ia by the aid of bitumen 7 filling the cup 8, which is inserted into the metal sleeve 9 of the tray.
Дл производства измерений рН каплю исследуемо жидкост 10 нанос т на поверхность электропровод щей стекл ниой J. После этого стекл нный электрод подвод т под каломельнь электрод //, укрепленный в штатив при потепциометре, и следовательно, капл м Дкости 10 при измерении рН находитс в контакте одновремен ю со стекл нным и каломельным электродами. Пространство между каломельным и стекл шым электродами должно быть огран 1чено To make pH measurements, a drop of the investigated liquid 10 is applied to the surface by electrically conductive glass J. After that, the glass electrode is brought under the calomel electrode //, mounted on a tripod at the heat gun, and consequently, Doc 10 drops at the pH simultaneously with glass and calomel electrodes. The space between the calomel and glass electrodes should be limited to 1.
