Description
смешивани двух газов при вытеснении необходимо , чтобы смешивание происходило только за счет диффузии, что достигаетс соответствуюшим выбором диаметра трубки-емкости ). При заполнении емкости 12 дозируемым газом ее полость посредством кранов 11 и 13 отсоедин етс от полости дозатора.mixing of two gases during displacement requires that mixing occurs only due to diffusion, which is achieved by the appropriate choice of the diameter of the tube-container). When filling the container 12 with the gas to be dosed, its cavity is disconnected from the cavity of the dispenser by means of taps 11 and 13.
Длина трубки-емкости находитс из следуюпдего соотношени :The length of the tube-tank is from the following relation:
3,61/1)/, тгО 3.61 / 1) /, nGO
где / - длина трубки; d - диаметр трубки;where / is the length of the tube; d is the diameter of the tube;
Q-расход газа дозируемого газа; t - врем , в течение которого дозаторQ-flow rate of gas dosed; t is the time during which the dispenser
должен работать непрерывно; D - коэффициент диффузии дозируемогоshould work continuously; D is the diffusion coefficient of the dosed
газа в газ-носитель.gas to carrier gas.
Предмет изобретени Subject invention
Дозатор дл получени газовых смесей, содержавший два капилл ра, соединенные выходными концами, и емкость дл дозируемого газа, отличающийс тем, что, с целью достижени посто нства концентрации получаемой смеси при изменении свойств дозируемого газа , емкость дл дозируемого газа установлена между выходны.мн концами капилл ров.A dispenser for gas mixtures containing two capillaries connected at the outlet ends and a container for the gas to be dosed, characterized in that, in order to achieve a constant concentration of the mixture when the properties of the gas to be dosed are changed, the capacity for the gas to be dosed is set between the ends of the gas capillary ditch
