Chromatograph mostly is on the purity of its gas componant content to the requirement of carrier gas at present, in case after having determined the purity of its gas content, do not take the means of any processing for the influence of residual air.
Generally when changing, carrier gas is easy to scurry into the gas that has moisture, and chromatographic column is chromatographic core component, because the characteristic of its structure has determined that moisture is very big to its influence, in case chromatographic column has moisture to pass through, the performance of this chromatographic column is deterioration sharply.
Therefore, need provide a kind of new carrier gas system that is used for gas chromatograph, it can provide dry carrier gas, thereby reduces moisture to chromatographic influence, guarantees the normal continuously work of chromatograph analysis, improves chromatograph and analyzes the precision of data and the life-span of instrument.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, a kind of novel carrier gas system that is used for gas chromatograph is provided, this novel carrier gas system design that is used for gas chromatograph is ingenious, simple in structure, it is convenient to transform, dry carrier gas can be provided, thereby reduce moisture to chromatographic influence, guarantee the normal continuously work of chromatograph analysis, not only improve the reliability and the measuring accuracy of system works, also prolong the life-span that chromatogram is divided instrument simultaneously, thereby reduced cost, be suitable for large-scale promotion application.
To achieve these goals, the novel carrier gas system that is used for gas chromatograph of the present utility model has following formation:
This is used for the novel carrier gas system of gas chromatograph, comprise carrier gas source with described gas chromatograph pipeline connection, be characterized in, the described novel carrier gas system that is used for gas chromatograph also comprises first device for drying and filtering, and described carrier gas source is by described first device for drying and filtering and described gas chromatograph pipeline connection.
Preferably, described first device for drying and filtering is a molecular sieve formula device for drying and filtering.
Preferably, the described novel carrier gas system that is used for gas chromatograph also comprises second device for drying and filtering, and described second device for drying and filtering and described first device for drying and filtering are arranged in parallel.
More preferably, described second device for drying and filtering is a molecular sieve formula device for drying and filtering.
More preferably, described first device for drying and filtering is a molecular sieve formula device for drying and filtering.
The beneficial effects of the utility model are specific as follows:
1. the utility model is by inserting device for drying and filtering between carrier gas source and gas chromatographicanalyzer, thereby enter gas chromatographicanalyzer again after making the carrier gas of coming out from carrier gas source by device for drying and filtering, design ingenious, simple in structure, it is convenient to transform, dry carrier gas can be provided, thereby reduce moisture to chromatographic influence, guarantee the normal continuously work of chromatograph analysis, not only improve the reliability and the measuring accuracy of system works, also prolong the life-span that chromatogram is divided instrument simultaneously, thereby reduced cost, be suitable for large-scale promotion application;
2. the utility model can adopt the mode of two device for drying and filtering parallel connections, and is easy to maintenance, can guarantee that chromatograph can need not stop chromatographic operation because of the replacing of device for drying and filtering, and chromatograph more can thereby not be affected because of the former of carrier gas.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the present utility model.
Fig. 2 is the structural representation of another specific embodiment of the present utility model.
Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Figure 1, Fig. 1 is a specific embodiment that is used for the novel carrier gas system of gas chromatograph of the present utility model, this novel carrier gas system that is used for gas chromatograph comprises the carrier gas source 2 with described gas chromatograph 1 pipeline connection, the described novel carrier gas system that is used for gas chromatograph also comprises first device for drying and filtering 3, and described carrier gas source 2 is by described first device for drying and filtering 3 and described gas chromatograph 1 pipeline connection.
Preferably, described first device for drying and filtering 3 is molecular sieve formula devices for drying and filtering.Obviously, first device for drying and filtering 3 also can adopt other device for drying and filtering.
Adopt this structure, the carrier gas of coming out from carrier gas source 2 enters gas chromatographicanalyzer 1 after by first device for drying and filtering 3 again, has guaranteed the quality of carrier gas, has therefore guaranteed that chromatographic column can thereby not be affected because of the former of carrier gas.
See also shown in Figure 2, Fig. 2 is another specific embodiment that is used for the novel carrier gas system of gas chromatograph of the present utility model, this novel carrier gas system that is used for gas chromatograph is except comprising first device for drying and filtering 3, also comprise second device for drying and filtering 4, described second device for drying and filtering 4 is arranged in parallel with described first device for drying and filtering 3.
Preferably, described second device for drying and filtering 4 is molecular sieve formula devices for drying and filtering.Obviously, second device for drying and filtering 4 also can adopt other device for drying and filtering.
Therefore, described first device for drying and filtering 3 can be identical device for drying and filtering with described second device for drying and filtering 4, also can be different devices for drying and filtering.
Adopt this structure, the carrier gas of coming out from carrier gas source 2 divides two-way respectively by entering gas chromatographicanalyzer 1 again behind first device for drying and filtering 3 and second device for drying and filtering 4, guaranteed the quality of carrier gas, therefore guaranteed that chromatographic column can thereby not be affected because of the former of carrier gas.Simultaneously,, when needing to change one of them device for drying and filtering, need not to stop chromatographic operation owing to have the device for drying and filtering of two parallel connections, easy to maintenance, still can guarantee the quality of carrier gas, so guarantee that chromatographic column can thereby not be affected because of the former of carrier gas.And when having single device for drying and filtering, need stop chromatographic operation, safeguard inconvenient.
