Изобретение относитс  к способам контрол  содержани  растворенных в в зких жидкост х газов и может быть использовано, например, при определении количества растворенного воздуха в пр дильных растворах дл  получени  волокон нитрон, армид, сульфон , вниивлон.The invention relates to methods for controlling the content of gases dissolved in viscous liquids and can be used, for example, in determining the amount of dissolved air in spinning solutions for the production of nitron fibers, armides, sulfones, and fibers.

В известном способе при измерении концентрации газа в жидкость ввод т пузырек газа и под микроскопом след т за изменением его размеров. Пузырьки газа получают предварительно в отдельном сосуде, засасывают в стекл нную трубочку нужеого размера и затем ввод т в жидкость. По времени растворени  пузырька, использу  закон Генр .и, определ ют концентрацию растворенного газа. Однако процесс измерени  продолжителен и недостаточно точен.In a known method, when measuring the concentration of a gas, a gas bubble is introduced into the liquid and, under a microscope, it monitors its size. The gas bubbles are first prepared in a separate vessel, sucked into the glass tube of the same size and then introduced into the liquid. The dissolved gas concentration is determined by the time of bubble dissolution, using Gen. However, the measurement process is long and not accurate enough.

С целью сокращени  времени измерени  и повышени  точности, предлагаетс  пузырек газа вводить с помощью пластины с калиброванным сквозным отверстием.In order to reduce measurement time and increase accuracy, it is proposed to introduce a gas bubble using a plate with a calibrated through hole.

Пример. Пластину с калиброваннымExample. Plate with calibrated

сквозным отверстием ввод т в сосуд (кювета ) с контролируемой жидкостью. При этом отсекаетс  определенный объем газа, наход щийс  в этом отверстии. Затем пластину поворачивают на 90° и пр.и легком движении вниз получают пузырек газа, изменение размеров которого контролируют. Один из конЦ01В кюветы, а следовательно, и отверстие в пластине, можно непрерывно продувать любым газом, что позвол ет исследовать абсорбдию не только воздуха.A through hole is introduced into a vessel (cuvette) with a controlled liquid. At the same time, a certain amount of gas in this hole is cut off. Then the plate is rotated 90 ° and a gas bubble is obtained, and a slight downward movement is obtained; the bubble of gas is monitored. One of the endpoints of the cuvette, and hence the hole in the plate, can be continuously blown with any gas, which allows us to study the absorption of not only air.
