[0038] Working principle: When using an industrial online gas chromatograph, the sample must first enter the filter box 3 from the feed port 4. At this time, the filter screen 27 and the L-shaped filter plate 5 filter the sample. At the same time, the switch 20 is turned on to allow the motor 11 to work and drive the first rotating rod 12 to rotate, causing the cylinder 14 to rotate through the rotating wheel 15 and the belt 16.
