Problems solved by technology
[0005]
The purpose of the present invention is to provide a rapid detection device for greenhouse gases, which is used to solve the problems in the prior art when detecting gas or liquid volatiles after solid or liquid samples are reacted due to the need for heating, headspace sampling, impurity removal, etc. A series of steps, but the existing equipment can only heat and transport the sampled gas samples one by one, which leads to the technical problems of long detection time and low efficiency

Embodiment Construction
[0027] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and extended understanding of the inventive concepts and technical solutions of the present invention.
[0028] Such as Figure 1-8 As shown, the present invention provides a rapid detection device for greenhouse gases, including a chromatographic detection device 1, such as a gas chromatograph, which uses a capillary column to separate substances. In addition, it also includes a sampling delivery system 7, a sampling movement mechanism 2, a lower heating box 4, an upper temperature control box 5, and a temperature control system. The lower heating box 4 is provided with an initial sample container 401, and the lower heating box 4 is connected to the The heated gas heats all the initial sample containers 401. The upper temperature con...

The invention discloses a rapid greenhouse gas detection device which comprises a chromatographic detection device, a sampling conveying system, a sampling movement mechanism, a lower heating box and an upper temperature control box, initial sample containers are arranged in the lower heating box, and heated gas is introduced into the lower heating box to heat all the initial sample containers; gas sample containers are arranged in the upper temperature control box, the gas sample containers are in one-to-one correspondence with the initial sample containers, and gas at a certain temperature is introduced into the upper temperature control box to control the temperature of the gas sample containers at a set temperature; the sampling and conveying system comprises sampling and conveying modules in one-to-one correspondence with the gas sample containers, and the sampling and conveying modules are used for realizing headspace sampling between the initial sample container and the gas sample containers and between the gas sample containers and the sampling needles. According to the invention, simultaneous heating and temperature control of a plurality of samples are realized through different box bodies, so that the consumed time is greatly reduced, and the detection efficiency is obviously improved.
Description
technical field [0001] The invention belongs to the technical field of chromatographic detection, and in particular relates to a rapid detection device for greenhouse gases. Background technique [0002] The Ecological Monitoring Planning Outline (2020-2035) proposes that greenhouse gases (including CO 2 、CH 4 , SF 6 , HCFCs, NF 3 , N 2 O, etc.) monitoring is included in the design of the routine monitoring system, in which nitrous oxide (N 2 O) is following carbon dioxide (CO 2 ), methane (CH 4 ) is the third largest greenhouse gas. [0003] N 2 The greenhouse effect of O is CO 2 206 times of , its production is often related to the process of nitrification and denitrification in the soil, which will not only reduce the utilization rate of fertilizers, but more importantly, be associated with global warming and the destruction of the ozone layer. In the indoor quantitative analysis method of nitrous oxide, gas chromatography is mainly used for quantitative analysi...
