Problems solved by technology

[0005] In order to overcome the shortcomings of the existing technology, a FID detector with an ultra-low detection limit is proposed to solve the problem that the detection limit is not precise enough when the FID detector is used for detection, and it is necessary to connect hydrogen and air to the detector. It is necessary to use a hose when transporting the gas. Because the hose is soft in use, when the hoses touch each other, they are prone to knotting, which prevents the normal delivery of the gas and affects the normal operation of the detector. The use of the problem, to achieve the effect of stable transport of gas

Abstract

The invention discloses an FID (Flame Ionization Detector) with an ultralow detection limit. The FID with the ultralow detection limit comprises a detector body and a dust-proof cap, wherein the top end of the interior of the detector body is provided with the dust-proof cap, the dust-proof cap is fixedly connected to the top end of the interior of the detector body through welding, a collecting electrode is installed below the dust-proof cap, the collecting electrode is fixedly connected to the bottom end of the dust-proof cap through a clamping groove, the left and right ends of the outer surface of the middle of the collecting electrode are provided with insulating sheets, the insulating sheets are fixedly connected to the outer surface of the middle of the collecting electrode throughscrews, the right side of the detector body is provided with a pressing plate, the pressing plate is parallel to the insulating sheets, the pressing plate is fixedly connected to the right side of thedetector body through welding. In the action of a normal external force, an air pipe and a hydrogen pipe can be protected, and a blocking phenomenon which appears because a pipe is bended is not generated, and mutual twisting and connecting between the pipes can be prevented, so the stable transmission of the air pipe and the hydrogen pipe to a gas is effectively protected, and the practicabilityis stronger.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to an ultra-low detection limit FID detector. Background technique [0002] The FID detector is a quality detector, which not only has the characteristics of high sensitivity and wide linear range, but also is relatively insensitive to changes in operating conditions and has good stability. It is especially suitable for routine analysis of constant or trace amounts. The FID detectors on the market are The general detection limit is: 1×1×10 -11 It is widely used in the detection of volatile hydrocarbons and many carbon-containing compounds. Because of its fast response, it can be used in conjunction with capillary analysis techniques to complete rapid analysis of traces. It is the most widely used in gas chromatography instruments. One of the wide range of detectors. At the same time, the gas chromatograph can be equipped with two independent hydrogen flame ionization detectors. ...
