The back flushing device comprises one 10-port valve, one in use for pre-cutting back flushing 2m PORAPAK N chromatograph column; the column selection device comprises four-connection valve, one 2m 5A chromatograph column and one PORAPAK Q chromatograph column 2m in length. The utility model can be employed to measure gases comprising N<SUB>2</SUB>, NO, N<SUB>2</SUB>O, NO<SUB>2</SUB>, CO, CO<SUB>2</SUB>, etc., which is convenient in operation, cheap in price and effective to measure the auto tail gas content.
Description
Technical field
The utility model belongs to a kind of gas chromatograph, is to analyze contained N in the vehicle exhaust
2, NO, NO
2, N

2With CO, NO and NO
2, N
2O, CO
2Separated by the PORAPAKN chromatographic column, treat NO and NO
2Do not flow out and CO flows out PORAPAK N chromatographic column also not enter the 5A chromatographic column be to switch the position of four-way to accompanying drawing 2, carrier gas 1 flow process is 14-12-5A chromatographic column-detecting device at this moment, N
2With advance detecting device one by one after CO separates again by the 5A chromatographic column, the flow process after carrier gas 2 this moment is come out from ten-way valve is a 4-5-PORAPAK Q-detecting device, NO and NO
2, N
2O, CO
2Be blown into PORAPAK Q, separate laggard detecting device again, treat CO
2Rotation ten-way valve 60 is spent the position of accompanying drawing 1 after flowing out ten-way valve PORAPAK N chromatographic column, and the flow process of carrier gas 2 is 3-4-PORAPAKN chromatographic column-8-7, and the heavy constituent blowback is gone out system.
