Изобретение относитс  к технике отбора нробы химически активного газа с замораживанием .This invention relates to a freezing gas sampling technique.

Известен способ отбора химически активно пробы газа путем ее замораживани  в сверхзвуковом расшир 1ОИ1емс  канале, при котором ироба иостунает в расшир ющийс  отборный канал,соедииенный с вакуумом.There is a known method of sampling a chemically active gas sample by freezing it in a supersonic expansion channel 1OI, in which the irob and the vent expands into an expanding selective channel connected to a vacuum.

Недостатком известного способа  вл етс  невозможность получени  достоверных проб. The disadvantage of this method is the impossibility of obtaining reliable samples.

По предлагаемому способу в пробу ввод т нейтральный газ с высокой тенлопроводностыо , имеюпи1Й температуру, меньшую температуры начала химической реакпии в пробе. Это позвол ет получать достоверные пробы. According to the proposed method, a neutral gas with a high tenon conductivity is introduced into the sample; it has a temperature lower than that of the beginning of the chemical reaction in the sample. This makes it possible to obtain reliable samples.

На чертеже показана схема осуществлени  описываемого способа.The drawing shows the implementation of the described method.

Сверхзвуковой поток движетс  иавстречу пробоотборнику. Отборный канал 1 св зан с каналом 2, который нодсоединен к вакуумной The supersonic flow moves and depresses the sampler. Selective channel 1 is associated with channel 2, which is not connected to the vacuum.

полости. Нейтральный газ подают по каналу 3. Попада  в пробу п c CПIИвa cь с ней, нейтральный газ снижает температуру пробы и прекращает в ней химическую реакцию, что позвол ет сохранить истпнный состав смеси, отобранпы в исследуемо точке газового потока . При тем 1ературе газового ioтока О каналу 4 1одвод т. а по каналу 5 отвод т охлаждающу о воду.cavities. Neutral gas is fed through channel 3. Once in the sample, the neutral gas reduces the temperature of the sample and stops the chemical reaction in it, which makes it possible to preserve the composition of the mixture that was taken at the gas flow point under study. At that rate, the gas inlet O of channel 4 is connected to one channel, and through channel 5 is drawn off to a cooling water.
