One ends of the chromatograph splitters are connected with connectors of the six-way sampling valve, and the other ends of the chromatograph splitters are connected with the flame photometric detector. The six-way sampling valve is provided with a switching valve, and the two chromatograph splitters are arranged in two column temperature boxes. The outer diameter of each chromatograph splitter is 3mm, the inner diameter is 2mm, the length is 1.5mm, and the chromatograph splitters are made of teflon. Two ends of each chromatograph splitter are connected with the connectors of the six-way sampling valve and the flame photometric detector through coupling nuts, and Teflon sealing washers are arranged between the chromatograph splitters and the coupling nuts. The microscale sulfur analyzer is capable of adapting to different sulfides with different characteristics and boiling points, shortens analyzing circles, reduces absorption on the sulfides and increases the lowest concentration value of detection.
