Abstract
The utility model relates to a kind of polarized electrode fork, and comprise jaw, joint sleeve and installation portion, the rear portion of described jaw is stretched in joint sleeve, is provided with installation portion at the middle part of joint sleeve.Described electrode fork is made up of left and right two bonding jumpers, its material is silver bar or silver-plated copper bar, and in the front end of every root bonding jumper, folding holds into symmetrical arc, forms a clamping section, can tightly be clipped on the metal shell of nozzle, make the metal shell of nozzle become a part for polarized electrode.Described installation portion is enclosed within the outside of joint sleeve, between installation portion and joint sleeve, be provided with insulation course.The beneficial effects of the utility model are: rational in infrastructure, can tightly be clipped on the metal shell of nozzle, make the metal shell of nozzle become a part for polarized electrode.Easy to operate, stability is high, long service life, and result of use is good.The number of times changing polarized electrode can be reduced, saved use cost.
Description
Technical field:
The utility model relates to a kind of polarized electrode fork, is mainly used in chromatographic detecting device, belongs to technical field of chemical.
Background technology:
If chromatographic column is the heart of chromatographic resolution, so, detecting device is exactly chromatographic eyes.The effect no matter chromatographic column is separated how well, if the detecting device do not had will " be seen " do not go out separating effect.Therefore, the detecting device of high sensitivity, high selectivity is the gordian technique of chromatograph development always.In flame ionization detector, polarized electrode and passive electrode are its topmost two parts, and the quality of polarized electrode and passive electrode directly decides the quality of whole chromatograph performance.At present, what adopt in flame ionization detector is silver polarized electrode ring, is unsettledly placed between nozzle and passive electrode, poor stability, and in the bottom of flame, temperature is large by the impact of flame, and oxidation is fast, and serviceable life is short, and change frequent, use cost is high.
Summary of the invention:
The purpose of this utility model is the deficiency in order to overcome existing polarized electrode ring, and provide a kind of easy to operate, stability is high, the polarized electrode fork of long service life.
For achieving the above object, the technical solution adopted in the utility model is:
A polarized electrode fork, comprise jaw, joint sleeve and installation portion, the rear portion of described jaw is stretched in joint sleeve, is provided with installation portion at the middle part of joint sleeve.
Further, described electrode fork is made up of left and right two bonding jumpers, its material is silver bar or silver-plated copper bar, in the front end of every root bonding jumper, folding holds into symmetrical arc, form a clamping section, can tightly be clipped on the metal shell of nozzle, make the metal shell of nozzle become a part for polarized electrode.
Further, described installation portion is enclosed within the outside of joint sleeve, between installation portion and joint sleeve, be provided with insulation course.
The beneficial effects of the utility model are: rational in infrastructure, can tightly be clipped on the metal shell of nozzle, make the metal shell of nozzle become a part for polarized electrode.Easy to operate, stability is high, long service life, and result of use is good.The number of times changing polarized electrode can be reduced, saved use cost.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Embodiment:
As shown in Figure 1, a kind of polarized electrode fork, comprise jaw (1), joint sleeve (2) and installation portion (3), the rear portion of described jaw (1) is stretched in joint sleeve (2), is provided with installation portion (3) at the middle part of joint sleeve (2).Described electrode fork is made up of left and right two bonding jumpers, its material is silver bar or silver-plated copper bar, and in the front end of every root bonding jumper, folding holds into symmetrical arc, forms a clamping section, can tightly be clipped on the metal shell of nozzle, make the metal shell of nozzle become a part for polarized electrode.Because polarized electrode fork is below jet hole, distance flame is comparatively far away, and temperature is little by the impact of flame, and oxidation is slow, long service life.Described installation portion (3) is enclosed within the outside of joint sleeve (2), between installation portion (3) and joint sleeve (2), be provided with insulation course.The material of described insulation course is good insulation preformance, resistant to elevated temperatures quartz or pottery.When polarized electrode fork is installed, the clamping section that every root bonding jumper front end folding holds into symmetrical arc is opened, be clipped on the metal shell of nozzle, because bonding jumper has elasticity, unclamp rear two bonding jumpers to be just clipped in tightly on the metal shell of nozzle, add the stability of polarized electrode fork, the metal shell of nozzle can also be made to become a part for polarized electrode, improve the degree of accuracy of detecting device further.When taking off polarized electrode fork, the clamping section that every root bonding jumper front end folding holds into symmetrical arc is opened, just easily can take off from the metal shell top of nozzle.
Claims (2)
1. a polarized electrode fork, comprise jaw, joint sleeve and installation portion, the rear portion of described jaw is stretched in joint sleeve, installation portion is provided with at the middle part of joint sleeve, it is characterized in that: described electrode fork is made up of left and right two bonding jumpers, its material is silver bar or silver-plated copper bar, and in the front end of every root bonding jumper, folding holds into symmetrical arc, forms a clamping section.
2. a kind of polarized electrode fork according to claim 1, is characterized in that: described installation portion is enclosed within the outside of joint sleeve, between installation portion and joint sleeve, be provided with insulation course.
