Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, the logical proportional valve 3 of the one or six logical proportional valve the 2, the 26, drying tube 4, the first injection port 5, the second injection port 6, the first chromatographic column 7, the second chromatographic column 8, conductance cell reference arm 9, conductance cell gage beam 10, FPD detecting device
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.In the embodiment in figure 1: the input termination sulfur hexafluoride gas of the one or six logical proportional valve the 1 and the 26 logical proportional valve 2, the output terminal of the one or six logical proportional valve 1 is communicated with conductance cell gage beam 9 through the first injection port 4, the first chromatographic column 6 successively, the output terminal of the two or six logical proportional valve 2 is communicated with FPD detecting device 10 through the second injection port 5, the second chromatographic column 7 successively, the inlet end of drying tube 3 is carried gas, output terminal connects respectively input end and the conductance cell reference arm 8 of the two or six logical proportional valve 2, the input end of output termination the one or the six logical proportional valve 1 of conductance cell reference arm 8.
When work, the initial position of the one or six logical proportional valve the 1 and the 26 logical proportional valve 2 is " sampling " state, tested SF
6sample gas divides two-way to enter respectively in the logical proportional valve 2 of the one or six logical proportional valve the 1 and the 26, carrier gas He
2the drying tube 3 of flowing through also divides two-way to enter respectively conductance cell gage beam 9 and FPD detecting device 10, because the logical proportional valve 2 of the one or six logical proportional valve the 1 and the 26 is positioned at " sampling " state, inner tested sample gas cannot enter the first chromatographic column 6 and the second chromatographic column 7 that connect below, therefore conductance cell gage beam 9 and FPD detecting device 10 do not have response signal output.When the one or six logical proportional valve 1 is switched to after " sample introduction " state, inner sample gas is brought in the first chromatographic column 6 by carrier gas, in sample gas, contained multiple decomposition product is through multiple adsorb, the desorption of the first chromatographic column 6, present in time the state of successively concentrating the chromatographic column of gushing out, enter after conductance cell gage beam 9, on time shaft, can produce the crest signal of order, demarcate this peak shape of post analysis by stratographic analysis special purpose workstation software, can obtain the corresponding gas composition type of different crests, concentration.Equally, when the two or six logical proportional valve 2 is switched to after " sample introduction " state, inner sample gas is brought in the second chromatographic column 7 by carrier gas, in sample gas, contained multiple decomposition product is through the multiple adsorb of the second chromatographic column 7, desorption, present in time the state of successively concentrating the chromatographic column of gushing out, enter after FPD detecting device 10, the spectrum that produces of burning is sent into photomultiplier after by the sulphur optical filter of FPD detecting device 10 (this optical filter only allows sulphur characteristic spectrum to pass through) colour filter and is converted to electric signal, the same crest signal that generates order on time shaft, demarcate this peak shape of post analysis by stratographic analysis special purpose workstation software, also can obtain the type of the corresponding sulfurous gas component of different crests, concentration.
