Цель изобретени - упрощение способа , повышение производительности и точности измерени .The purpose of the invention is to simplify the method, increase productivity and measure accuracy.
Пример. Устройство с подложкой из полиэтиленоксидной пленки помещают в зоне действи факела распыл емой воды и включают распылитель. Контактирование с подложкой осуществл ют открытием окна. Врем контактировани определ ют опытным путем, Планшетку с пленкой и осевшими на ней капл ми извлекают из устройства. После высыхани пленки готов т препаратExample. The device with a polyethylene oxide film substrate is placed in the zone of action of the spray of water sprayed and includes a sprayer. Contacting with the substrate is carried out by opening the window. The contact time is determined experimentally, the tablet with the film and the droplets deposited on it are removed from the device. After the film has dried, a preparation is made.
дл микроскопировани и помещают под микроскоп фирмы Оптон (ФРГ), вход щий в комплект анализатора изображений ИБАС-2. В последнем оптическое изображение с помощью телевизионной передающей трубки преобразуетс в форму электрического сигнала. Информацию обрабатывают с помощью ЭВМ и вывод т через цифропечатающее устройство. Измерение отпечатков капель, т.е. дисперсности частиц аэрозол , провод т в отраженном свете. Увеличение контрастировани отпечатков от фона осуществл ют, подкладыва под подложку черную бумагу. В дальнейшем провод т измерение в автоматическом режиме перемещени препарата. Дл определени счетной концентрации частиц подсчитывают количество частиц в пол х зрени и относ т его к общей площади полей зрени .for microscopying and placed under an Opton microscope (FRG), included in the IBAS-2 image analyzer kit. In the latter, the optical image is converted into an electrical signal by a television transmission tube. The information is processed by a computer and output through a digital printing device. Measuring droplet prints, i.e. the dispersion of aerosol particles, carried out in reflected light. Increasing the contrast of prints from the background is carried out by placing black paper under the substrate. In the future, the measurement is carried out in the automatic mode of movement of the drug. To determine the number concentration of particles, the number of particles in the field of view is calculated and referred to the total area of the field of view.
