Abstract
The invention discloses a highly toxic substance heating sample injector combined with an alarm and belongs to the technical field of chemical defense. The highly toxic substance heating sample injector combined with an alarm comprises a cell cover, an aluminum box, cells, a switch button, a heating indicator light, a carbon steel barrel, a heating element, an acquisition probe and a wrist strap. Peripheral equipment comprises alarm equipment. The wrist strap is fixedly connected to the cell cover. The cell cover is fixedly connected to the aluminum box. The aluminum box is fixedly connected to the carbon steel barrel. The carbon steel barrel is fixedly connected to the acquisition probe. The highly toxic substance heating sample injector is connected to the alarm by a feeding connector and a feeding adapter. The highly toxic substance heating sample injector can heat and vaporize highly toxic substances having low volatility thereby realizing detection of a trace amount of the highly toxic substances having low volatility.
Description
technical field [0001] The invention relates to a highly toxic substance heating sampler used in conjunction with an alarm, in particular to a sampler for military low-volatility highly toxic chemicals, which belongs to the technical field of chemical defense. Background technique [0002] Military highly toxic chemicals are highly dangerous compounds. When people accidentally inhale or touch them, they will cause certain harm to the human body. Using alarm equipment to detect them is one of the important measures to ensure safety. However, some highly toxic chemicals are solid at normal temperature or solid or liquid at low temperature, or in solvents such as soil, solid waste, and water. Although there are relatively large amounts of highly toxic substances, the toxic dose volatilized is very small. Such as military highly toxic chemicals mustard gas, diphenylcyanarsine, diphenylchloroarsine, etc., which are lower than the detection limit of commonly used alarm equipment, ...
