Description

Изобретение может быть использовано дл  препарировани  аэрозольпых объектов при их электронномикроскопическом изучении.The invention can be used for the preparation of aerosol objects during their electron microscopic study.

Известны каскадные импакторы, которые можно использовать дл  фракционированного осаждени  аэрозолей. Однако эти импакторы не приспособлены дл  получени  проб, пригодных дл  непосредственного электронномикроскопического изучени  с достаточно высокой точностью.Cascade impactors are known that can be used for fractionated aerosol deposition. However, these impactors are not adapted for obtaining samples suitable for direct electron microscopic study with a sufficiently high accuracy.

Цель изобретени  - повышение точности элект,р01П,номи1к;роскопического .изучени  аэрозолей . Цель достигаетс  тем, что кажда  ступень предлагаемого импактора имеет устройство дл  закреплени  улавливающих поверхностей , выполненное в виде цилиндрической вставки со специальным гнездом дл  подложкодержателей .The purpose of the invention is to improve the accuracy of electroplating of aerosols. The goal is achieved by the fact that each stage of the proposed impactor has a device for fixing catching surfaces, made in the form of a cylindrical insert with a special socket for substrate holders.

Иа фиг. 1 изображен предлагаемый пмпактор , продольный разрез; на фиг. 2 - устройство дл  осаждени .FIG. 1 shows the proposed PMP, a longitudinal section; in fig. 2 — Deposition device.

Импактор содержит ступени (сопла) 1-4. и штуцер 5. Кажда  ступень имеет сквозные каналы 6, в которые вставл ют устройства 7 дл  осаждени  аэрозолей. Устройство 7 имеет гнездо 8 дл  подложек, представл ющих собой опорпые сетки с пластиковой пленкой.Impactor contains steps (nozzles) 1-4. and choke 5. Each stage has through channels 6 into which devices 7 are inserted to deposit aerosols. Device 7 has a slot 8 for substrates that are foil grids with plastic film.

Устройство 7 легко снимаетс  без разборки импактора.The device 7 is easily removed without disassembling the impactor.

Работает импактор следующим образом.Impactor works as follows.

Через прибор прокачивают аэрозоль со скоростью около 6 л/мин. Продолжительность отбора проб зависит от концентрации изучаемого аэрозол  и составл ет 10-15 сек. После прокачки устройства 7 вынимают и из них извлекают подложки, которые затем обрабатывают по общеприн той методике (фиксаци , диалез, коптрастирование) и исследуют в электронном микроскопе.The aerosol is pumped through the device at a speed of about 6 l / min. The duration of sampling depends on the concentration of the aerosol under study and is 10-15 seconds. After pumping, the devices 7 are removed and the substrates are removed from them, which are then processed according to a conventional technique (fixation, dialyz, blotting) and examined under an electron microscope.

Предмет изобретени Subject invention

Каскадный импактор дл  изучени  биологических и физических аэрозолей, состо щий из последовательно установленных ступеней в одном корпусе, кажда  из которых представл ет собой сопло с устройством дл  осаждепи  аэрозолей, отличающийс  тем, что, с целью повышени  точности прп электронномдакроскопическол изучеп:ии аэрозолей, устройство дл  осаждени  выполнено в виде цилиндрической вставки с гнездом дл  креплеПИЯ держателей электронномикроскопических подложек, па которые производитс  осаждение аэрозолей.A cascade impactor for the study of biological and physical aerosols, consisting of sequentially installed steps in a single housing, each of which is a nozzle with an aerosol deposition device, characterized in that, The deposition is made in the form of a cylindrical insert with a socket for fastening the holders of electron microscopic substrates, which are used for the deposition of aerosols.
