Embodiment 1

[0031] A clamping unit for a sampling syringe, comprising a syringe clamp for clamping the sleeve 1 of the sampling syringe, a piston follower 8 for providing guidance to the pressing plate 3 of the sampling syringe, and the The sleeve 1 of the sampling syringe is engaged with the chuck 9 fixed on the syringe holder, and the piston follower 8 is slidably connected to the rear of the syringe holder through a sliding assembly, wherein:

[0032] The front end of the front positioning part 10 is a positioning plate 15, and a sample gas outlet 16 and a purge port 17 are formed on the positioning plate 15, and a first connecting pipe 18 is fixed on the sample gas outlet 16 to connect the sampling gas. The front port 6 of the syringe, the second connecting pipe 19 is fixed on the purge port 17 to connect to the side port 5 of the sampling syringe.

[0033] When fixing the sampling syringe to the clamping unit, first place the sampling syringe in the syringe clamping part, insert the ...

Embodiment 2

[0043] Such as figure 2 As shown, in this embodiment, after the sampling unit clamps the sampling syringe, it is driven by an external driving mechanism, that is, the driving mechanism in this embodiment is not assembled in the sampling unit,

[0044] In order to provide space for the sample injection drive mechanism to drive the piston push handle 2, the tail portion of the syringe holder is formed with a circular hole 22 for the drive end of the sample injection drive mechanism to enter.

Embodiment 3

[0046] Such as Figure 4 As shown, in this embodiment, after the sampling unit clamps the sampling syringe, it is driven by the self-assembled driving unit.

[0047] A drive unit 27 is fixed to the tail of the syringe holder, and a drive end of the drive unit 27 is fixedly connected to the pressing plate. The drive unit may be a linear feed unit such as a linear motor or an electric cylinder.

Abstract

The invention discloses a clamping unit of a sampling injector and a clamping method of the clamping unit. The clamping unit comprises an injector clamping piece used for clamping a sleeve of the sampling injector, a piston follower used for guiding a pressing plate of the sampling injector, and a chuck used for clamping and fixing the sleeve of the sampling injector to the injector clamping piece. The piston follower is connected to the rear portion of the injector clamping piece in a sliding mode through a sliding assembly. A positioning plate is arranged at the front end of the injector clamping piece, a sample gas outlet and a purging opening are formed in the positioning plate, a first connecting pipe is fixed to the sample gas outlet so as to be connected with a front end opening ofthe sampling injector, and a second connecting pipe is fixed to the purging opening so as to be connected with a side end opening of the sampling injector. The clamping unit provided by the inventioncan effectively position the sampling injector.

Description

technical field [0001] The invention relates to the technical field of gas analysis, in particular to a clamping unit of a sampling syringe and a clamping method thereof. Background technique [0002] Climate warming is a major challenge that the world is currently facing. The Fifth Assessment Report of the IPCC stated that the main cause of global warming is the sharp increase in the concentration of greenhouse gases in the atmosphere. According to reports, nearly 5%-20% of CO in the atmosphere every year 2 , 15%-30%CH 4 and 80%-90%N 2 O is all derived from the soil. As the global climate continues to warm, the degradation of permafrost and the melting of glaciers have a great impact on greenhouse gas emissions. In order to understand the production mechanism of greenhouse gases and quantify the contribution rate and influencing factors of soil and glacier greenhouse gases to atmospheric emissions, it is necessary to use isotope technology to solve the problem. [0003]...
