Abstract
The utility model provides the technical scheme of the online degasser of a kind of ion chromatograph, the device of the program, comprise housing, be arranged on the osmos tube in housing, vacuum pump, it is characterized in that: vacuum pump is communicated with enclosure interior by pipeline, housing is provided with electric heater, housing is also provided with ion chromatograph stream joint, ion chromatograph stream joint is communicated with osmos tube, utilize the pressure reduction inside and outside osmos tube to carry out degassed, housing is provided with thermistor RT.The device of the program, heats, improves degassing efficiency while degassed, avoids Yin Wendu to affect secondary and produces bubble molecule.
Description
Technical field
The utility model relates to a kind of ion chromatograph, especially a kind of online degasser for ion chromatograph.
Background technology
In the prior art, known technology is in liquid-phase chromatographic analysis process, the gas be dissolved in mobile phase is overflowed in the form of bubbles when mixing, it not only affects the separation efficiency of chromatographic column, and affect the stability desensitization of detecting device baseline, so the gas in mobile phase will be removed, vacuum pump is mostly used to twitch gas at present, make osmos tube inside and outside generation pressure reduction, in mobile phase, dissolved gases just can be got rid of by infiltration tube wall, but due in degassed process, temperature can change, bubble can be produced by secondary, subsequent detection sensitivity can be affected like this.This is the weak point existing for prior art.
Summary of the invention
The purpose of this utility model is exactly for the deficiency existing for prior art, and provide the technical scheme of the online degasser of a kind of ion chromatograph, the device of the program, heat while degassed, improve degassing efficiency, avoid Yin Wendu to affect secondary and produce bubble molecule.
This programme is achieved by the following technical measures: the online degasser of a kind of ion chromatograph, comprise housing, be arranged on the osmos tube in housing, vacuum pump, the feature of this programme is: vacuum pump is communicated with enclosure interior by pipeline, housing is provided with electric heater, housing is also provided with ion chromatograph stream joint, ion chromatograph stream joint is communicated with osmos tube, housing is provided with thermistor RT, one end of thermistor RT is connected by the first resistance R1 and VCC, the other end of thermistor RT is by slide rheostat RP ground connection, thermistor RT is connected with the base stage of a triode VT by the second resistance R2 with slide rheostat RP junction, the grounded emitter of triode VT, the emitter of triode VT is connected with VCC by the first relay J, there is a pilot lamp L in parallel with relay J, an electric capacity C1 is connected in series between described VCC and the emitter of triode VT, the normally opened contact J-1 of relay J connects with electric heater.
Described housing is metal shell.
Described osmos tube is armorphous fluororesin deaeration pipe.
Described relay J is auxiliary reclay.
Described ion chromatograph stream joint quantity is n, n is even numbers, and n >=2.
Corresponding two the ion chromatograph stream joints of each osmos tube, the two ends of osmos tube respectively with two ion chromatograph stream fittings.
Described pilot lamp L is LED.
Described VCC is+3V.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to having vacuum pump in this scenario, the strength pressure in housing can be reduced, the pressure in osmos tube is made to be greater than pressure in housing, be beneficial to carry out degassed, housing is provided with thermistor, temperature variation can be obtained timely, when the temperature is low, the resistance of thermistor increases, triode ON, the electricity of relay, the normally opened contact of relay closes, electric heater starts heating, after temperature raises, the resistance of thermistor increases, during to setting value, triode ends, relay electric-loss, electric heater quits work, housing is metal shell, is beneficial to heat conduction, pilot lamp is LED, saves electric energy, corresponding two the ion chromatograph stream joints of each osmos tube, the two ends of osmos tube respectively with two ion chromatograph stream fittings, be beneficial to connection external unit, be convenient to the turnover of mobile phase.As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent in the present invention.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the circuit diagram of the utility model embodiment.
In figure, 1 is housing, and 2 is osmos tube, and 3 is electric heater, and 4 is pipeline, and 5 is ion chromatograph stream joint, and 6 is vacuum pump.
