Abstract
The utility model provides a gas injection port with a filtering function of a gas chromatographic analyzer, belongs to the technical field of gas chromatographic analyzers, and solves the problems that an analyzing result has an error due to that an injected sample contains grains or the analyzer is damaged and the like. The gas injection port comprises a gas sample injection pipe, wherein the gas sample injection pipe is internally provided with a filtering core; the filtering core is made of a metal material; the filtering core is blocked in an injection pipe cavity; a plurality of airflow passing holes are formed in the filtering core. The gas injection port with the filtering function of the gas chromatographic analyzer has the advantages of effectively filtering the impurity grains, guaranteeing the operation stability of machines, the accuracy of data analysis and the like.
Description
Technical field
The utility model belongs to the gas chromatographicanalyzer technical field, refers in particular to a kind of gas chromatographicanalyzer gas sampling mouth with filtering function.
Background technology
At present, the gas sampling mouth of commodity gas chromatograph, all do not take certain measure with reduce or remove may impurity and particle.
The analysis of gaseous sample can adopt gas sampling pin hand sampling or sampling valve sample introduction.Valve injection, with its simple operation, the many merits such as quantitatively accurate, reproducible, is adopted by increasing analyst.Owing to differing in the sample gas source, contain solid impurity or molecule in some sample, if these impurity and particle enter the analytic system of gas chromatograph, just analytic system that can the contamination gas chromatography, interference analysis, even can cause chromatographic column stop up and scrap.Therefore, take certain measure to remove solid impurity and the molecule in these gaseous samples, for improving the analysis result accuracy, guarantee gas chromatograph stable operation, have great importance.
Summary of the invention
The purpose of this utility model is to provide a kind of gas chromatographicanalyzer gas sampling mouth with filtering function, it was provided with the impurity of filter core for filtering gas on the gas sampling mouth, prevent that particle from entering chromatographic analysis system and causing systemic contamination or obstruction, one-piece construction is simple and practical.
The purpose of this utility model is achieved in that
Gas chromatographicanalyzer gas sampling mouth with filtering function, comprise the gas sample introduction pipe, it is characterized in that: in described sample feeding pipe, be provided with filter core, the described filter core of crossing adopts metal material to make, described filter core shutoff excessively is arranged in the sample introduction tube chamber, excessively on filter core, offers some air-flows and passes through hole.
In the above-mentioned gas chromatographicanalyzer gas sampling mouth with filtering function, described filter core excessively is filter net sheet, and the outer side edges of filter net sheet is connected with the inner wall sealing of sample feeding pipe.
The utility model outstanding and useful technique effect compared to existing technology is:
Of the present utility model simple in structure, be, at the injection port place, filter core was set, this is crossed filter core and can be the structure settings such as filter net sheet, offers air-flow on filter net sheet and passes through hole, effectively the magazine particle filtering is fallen, guaranteed the machine operation stable and data analysis precisely.
The accompanying drawing explanation
Fig. 1 is structure cut-open view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1:
Gas chromatographicanalyzer gas sampling mouth with filtering function, comprise gas sample introduction pipe 1, it is characterized in that: be provided with filter core 2 in described sample feeding pipe, the described filter core of crossing adopts metal material to make, described filter core shutoff excessively is arranged in the sample introduction tube chamber, crosses on filter core and offers some air-flows by hole 3.
Described filter core excessively is filter net sheet, and the outer side edges of filter net sheet is connected with the inner wall sealing of sample feeding pipe.The filter core of crossing in the utility model is not limited to filter net sheet, and the filtration with better filtering gas endoparticle magazine all can adopt.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
Claims (2)
1. the gas chromatographicanalyzer gas sampling mouth that there is filtering function, comprise gas sample introduction pipe (1), it is characterized in that: be provided with filter core (2) in described sample feeding pipe, the described filter core of crossing adopts metal material to make, described filter core shutoff excessively is arranged in the sample introduction tube chamber, crosses on filter core and offers some air-flows by hole (3).
