Furthermore, the sampling chamber 2 is sealed by an acrylic plate and is provided with a door 6 on the front surface, so that the sampling bottle 1 can be conveniently replaced. Attractive appearance and convenient transparent observation.
The sampling chamber 2 is provided with a placing hole, the sampling bottle 1 passes through the placing hole and is connected with the quick connector 5, and a sealing device is arranged between the sampling bottle 1 and the placing hole.
The sampling bottle 1 is made of stainless steel, stainless steel needle valves are arranged on the upper part and the lower part, the tightness is strong, and the safety in the sampling and lofting processes is fully ensured. When a sample in the sampling bottle 1 enters the chromatograph, the sample can be quickly made to enter the chromatograph by adopting a stainless steel quick connector mode, so that the emission of the sample is reduced, and the sample is convenient and quick.
The side wall of the sampling bottle connecting seat 4 is provided with an air nozzle, the air nozzle is connected with one end of a first tetrafluoro tube 10, the other end of the first tetrafluoro tube 10 extends out of the sampling chamber 2 through an opening on the side wall of the sampling chamber 2 and is connected with a flash evaporation device, and a sealing device is arranged between the first tetrafluoro tube 10 and the opening.
The waste liquid bottle 3 open department be equipped with upper cover 301, open and have two through-holes on the upper cover 301, second tetrafluoro pipe one end stretches into in the waste liquid bottle 3, the other end passes through the through-hole on the upper cover 301 and the trompil on the sampling chamber 2 lateral wall in proper order and stretches out sampling chamber 2 outside and link to each other with the chromatograph, third tetrafluoro pipe (not shown in the figure) one end stretches into in the waste liquid bottle 3, the other end passes another through-hole on the upper cover 301 and exhaust vent 8 in proper order stretches out sampling chamber 2 outside and exhaust duct link to each other, sealing device is equipped with between the trompil on second tetrafluoro pipe and the sampling chamber 2 lateral wall.
Wherein, 2 holes are opened on the side wall of the sampling chamber 2, which are respectively used for the first tetrafluoro tube 10 and the second tetrafluoro tube (not shown in the figure) to extend out of the sampling chamber 2, and sealing devices, such as sealing rings, are arranged between the first tetrafluoro tube 10 and the second tetrafluoro tube and the open holes. The glass bottle with the plug is used as the waste liquid bottle 3, can well absorb waste gas generated in the analysis process of the chromatograph, and then exhaust the waste gas through the exhaust pipe, thereby achieving the effect of reducing environmental pollution.
