Description
Technical field
The utility model relates to twice sampling device of a kind of gas chromatograph gas analysis, belongs to the component class of gas chromatograph.
Background technology
The input mode of gas chromatograph argoshield analysis generally adopts the six-way valve sampling technique, twice sample introduction analysis if desired, then need two six-way valves, sample is replaced by two six-way valves respectively, distinguishes sample introduction then, whole process operation trouble, because time swap is inconsistent, may cause problems such as leakage, absorption, introduce personal error easily, impact analysis result's accuracy.
The utility model content
The purpose of the present utility model: aim to provide a kind of novel twice input mode of gas chromatograph gas analysis, overcome the troublesome poeration that existing universal method exists, introduce shortcomings such as personal error easily.
Twice sampling device of this gas chromatograph gas analysis is made up of two gas six-way valves, threeway sample introduction pipe and connecting line, it is characterized in that:
A, described gas six-way valve are one group of synthetic six-way valve 1 of matched group and six-way valve 2, wherein the valve opening 2-6 of the valve opening 1-3 of six-way valve 1 and six-way valve 2 forms sample gas sample introduction pipelines through a threeway sample introduction pipe 3, simultaneously again with six-way valve 1, six-way valve 2 in valve opening 1-2 and valve opening 2-1 constitute and discharge stream;
The valve opening 1-5 of B, described six-way valve 1 is connected with analysis chromatographic column 4-1, and the valve opening 1-6 in the six-way valve 1 detects the stream carrier gas inlet for this, valve opening 1-1 then is communicated with valve opening 1-4 by quantity tube 5-1, forms thus to analyze the detection stream of chromatographic column 4-1;
The valve opening 2-4 of C, described six-way valve 2 is connected with analysis chromatographic column 4-2, and the valve opening 2-3 in the six-way valve 2 detects the stream carrier gas inlet for this, valve opening 2-2 then is communicated with valve opening 2-5 by quantity tube 5-2, forms thus to analyze the detection stream of chromatographic column 4-2.
Twice sampling device of this gas chromatograph gas analysis according to above technical scheme proposition, compare with twice sampling device of existing conventional gas-phase chromatograph gas analysis, overcome the defective that existing fexible unit exists, reduced operation link, thereby reduced the chance of introducing error, made accuracy of analysis greatly improve.
