Abstract
The invention provides an electric fishing detector lining device of a gas chromatograph and belongs to the technical field of analytical test instruments. The electric fishing detector lining device adopts a lining body made of a stainless steel pipe, a stainless steel column joint is arranged at the lower end of the lining body through argon arc welding, and a quartz jet nozzle provided with a hemisphere at the upper portion and a thin and small hole in the middle is sintered at the upper end of the lining body. The upper portion of the stainless steel column joint is a hexahedron, the lower portion of the stainless steel column joint is an outer wire with a tool return slot, a small through hole is formed in the center, and a large horn mouth is formed in the lower end of the small through hole. The electric fishing detector lining device of the gas chromatograph is changed into a cleaning type electric fishing detector lining device on the premise that an original cavity structure of a gas chromatograph electric fishing detector is not changed, so that a detected chemical sample is not directly in contact with a radioactive source, the radioactive source is prevented from being polluted, the stability and the sensitivity of the lining device are ensured, the accuracy of detection results of the lining device is improved, and the lining device is simple in structure and convenient to install.
Description
Technical field
The invention belongs to analytical and testing instrument technical field, relate to a kind of gas chromatograph electric fishing detector inner lining structure design.
Background technology
When gas chromatograph electric fishing detector is analyzed, the liner of its electric fishing detector is exactly one section of stainless steel tube or glass tubing,
So detected chemical example directly contacts with radioactive source, and makes radioactive source be contaminated, and causes electric fishing detector noise big, clever
Sensitivity declines, and causes testing result poor accuracy.
Summary of the invention
The present invention provides a kind of gas chromatograph electric fishing detector inner lining apparatus, it is characterized in that: use stainless steel tube to do inner lining body,
The following argon arc of inner lining body is welded with rustless steel column joint, and the top of inner lining body sintering has top to be that hemisphere, centre have Small Holes
Quartz nozzle；Rustless steel column joint, top be hexahedron, bottom be take back the outer silk of cutter groove, there are small through hole, small through hole in center
Following have typhon mouth.
Beneficial effects of the present invention: provide gas chromatograph electric fishing detector in the case of not changing its original cavity body structure,
So that it becomes a kind of electric fishing detector inner lining apparatus of clean type, make the chemical example being detected directly not contact with radioactive source, keep away
Exempt from radioactive source to be contaminated, it is ensured that its stability and sensitivity, improve the accuracy of its testing result, and simple in construction,
Easy for installation.

Detailed description of the invention
The inner lining body detailed description of the invention of the present invention, is shown in accompanying drawing 1, and the stainless steel tube using internal diameter to be 1mm does inner lining body (1),
Top inner orifice is processed into thin counterbore (2), and following inner orifice is processed into the middle horn mouth (3) of 60 °.
The nozzle detailed description of the invention of the present invention, accompanying drawing 2, the fine quartz pipe using internal diameter to be 0.6mm makes nozzle (4), on
Head is processed into hemisphere (5), and following inner orifice is processed into the Herba Cladoniae verticillatae mouth (6) of 60 °.
The column joint detailed description of the invention of the present invention, is shown in accompanying drawing 3, uses six side's stainless steel bars to make column joint (7), centre drill
Small through hole (8), the end opening of small through hole (8) has the typhon mouth (9) of 60 °, and following is processed into be taken back outside cutter groove (10)
Silk (11), top stays one section of hexahedron (12), and the suitable for reading of small through hole (8) is processed into thick counterbore (13).
The whole implementation mode of gas chromatograph electric fishing detector inner lining apparatus of the present invention, is shown in accompanying drawing 4, by under inner lining body (1)
Head is put in thick counterbore (13) the inner argon arc welding (14) of column joint (7) top；Nozzle (4) following is put into inner lining body (1)
The thin counterbore (2) of top is inner, fills up silica flour sintering (15) firm.When this inner lining apparatus is loaded electric fishing detector, its spray
The hemisphere (5) of mouth (4) has just been inserted into the top of radioactive source in cavity, makes the chemical example that is detected not directly and radioactive source
Contact, it is to avoid radioactive source is contaminated.
Claims (1)
1. a gas chromatograph electric fishing detector inner lining apparatus, is characterized in that: use stainless steel tube to do inner lining body, under inner lining body
Head argon arc is welded with rustless steel column joint, and the top of inner lining body sintering has top to be the quartz nozzle that there is Small Holes hemisphere, centre；
Rustless steel column joint, top be hexahedron, bottom be take back the outer silk of cutter groove, there is small through hole at center, the following of small through hole has greatly
