Description

Изобретение относитс  к способу отбора, консервации и хранени  запахов в области криминалистической одорологии и может быть использовано в других област х, где требуетс  производить отбор, консервацию и хранение запахов.The invention relates to a method for the selection, preservation and storage of odors in the field of forensic odorology and can be used in other areas where it is necessary to select, preserve and store odors.

Известен прибор отбора запахов, включающий поршневой насос (медицинский или ветеринарный шприц) и герметичный контейнер (полиэтиленова  или стекл нна  емкость) Ц.A device for the selection of odors is known, which includes a piston pump (medical or veterinary syringe) and a sealed container (polyethylene or glass container) C.

Прибор характеризуетс  недостаточной достоверностью пробы, так как точечный забор воздуха с молекулами запаха, малый объем заборника и последующа  перекачка его в баллон (фл гу), в котором также находитс  воздух с Какими-то побочными молекулами запаха, значительно разжижает (разбавл ет) отобранный Воздух с молекулами запаха, что приводит к отрицательному результату в процессе выборки при помощи розыскной собаки. Забй воздуха с молекулами запаха с разных объектов производитс  одним шприцем с последующей перекачкой в баллон дл  хранени  запаха. После каждого забора камера и поршень шприца не обрабатываютс . На их гЛзверхности остаютс  молекулы запаха, которые ранее отбирались и перекачивались в баллон. При последующем воздуха с запахами, они раствор ютс  в нем и внос т дополнение. Газовьщеление из полиэтилена значительно высокое , поэтому во фл гах из полиэтилена хранить воздух с молекулами запаха с места происшестви  нежелательно. The device is characterized by insufficient reliability of the sample, as a point intake of air with odor molecules, a small volume of the intake and its subsequent transfer to a balloon (fl), which also contains air with some odor side molecules, significantly dilutes (dilutes) the selected Air with odor molecules, which leads to a negative result in the process of sampling with the help of a search dog. Air from odor molecules from different objects is produced with a single syringe and then transferred to an odor storage container. After each intake, the chamber and the piston of the syringe are not processed. Odor molecules, which were previously collected and pumped into a balloon, remain on their upper surfaces. With subsequent air with odors, they dissolve in it and add to it. The gas gap from polyethylene is significantly high, therefore, it is undesirable to store air with odor molecules from the scene in polyethylene fluids.

10 Кроме этого, стекло-материал хрупкий, изготовление из него контейнера дл  хранени  воздуха с молекулами запаха, изъ того с места происшестви , нецелесообразно , так как к месту прес15 туплени  часто приходитс  добиратьс  по неблагоустроенным дорогам, а иногда и по бездорожью. Это может привести к утрате ценнейших вещественных доказательств.10 In addition, the glass material is fragile; making an air storage container with odor molecules removed from the scene of the incident is impractical, since it is often necessary to get to the site of pressure by unsuitable roads and sometimes off-road. This can lead to the loss of valuable material evidence.

Цель изобретени  - повышение достоверности пробы за счет увеличени  срока хранени  воздуха с молекулами ;запаха.The purpose of the invention is to increase the reliability of the sample by increasing the shelf life of air with molecules; odor.

Поставленна  цель достигаетс  тем, 25 что прибор дл  отбора, консервации и хранени  воздуха, включающий поршневой насос и герметичный контейнер, снабжен съемной капсулой с обратными клапанами, соединенной с насосом, The goal is achieved by the fact that the device for sampling, preserving and storing air, including a piston pump and a sealed container, is provided with a removable capsule with non-return valves connected to the pump,
