Embodiment Construction

[0076] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0077] The invention provides an automatic sampling device for a gas adsorption tube, which relates to the technical field of indoor and outdoor air environment detection, and in particular relates to the field of sampling by using a gas adsorption tube to detect gas components. The sampling time, sampling duration, and Automatic tube loading, automatic sampling, and automatic putting back the adsorption tube, so that in a sampling cycle, no manual intervention is required to realize the full automation of the sampling process, which can not only save the current rising l...

Abstract

The invention provides an automatic sampling device and an automatic sampling method for a gas adsorption pipe. The automatic sampling device comprises a gas adsorption pipe feeding and discharging mechanism, a gas adsorption pipe decapping mechanism, a gas adsorption pipe sealing mechanism, a rotary clamping mechanism and a sampling control mechanism, the gas adsorption pipe feeding and discharging pipe is provided with multiple hole positions for clamping of the gas adsorption pipe, the gas adsorption pipe decapping mechanism is used for pulling down and clamping caps at two ends of the gasadsorption pipe taken down from the gas adsorption pipe feeding and discharging mechanism, and the rotary clamping mechanism is used for controlling circulation of the gas adsorption pipe among the mechanisms. Compared with existing sampling modes, the automatic sampling device and the automatic sampling method have the advantages that an operator only needs to mount and clamp the gas adsorption pipe onto a turnplate of the feeding and discharging mechanism, set sampling parameters and taking away the gas adsorption pipe after sampling is completed, so that the operator is avoided repeatedly working for a long time on a large scale. Therefore, an automatic sampling system saves both time and cost.

Description

technical field [0001] The invention belongs to the technical field of indoor and outdoor air environment detection, and in particular relates to an automatic sampling device and an automatic sampling method for gas adsorption tubes. Background technique [0002] In the field of indoor and outdoor air environment detection, gas adsorption tubes are widely used. Such as Tenax gas adsorption tube, Dnph gas adsorption tube, etc. During the detection, the inspector makes the gas to be detected pass through the adsorption tube through the atmospheric sampler, so that the adsorption tube is enriched with the gas to be tested. After the sampling is completed, the gas in the adsorption tube is desorbed and analyzed in the gas chromatograph, so that Qualitative analysis of the composition and content of the gas to be measured. [0003] In the prior art, when the gas adsorption tube is used to collect the gas to be measured, it is mainly manual operation. That is: it is necessary t...
