Abstract
The utility model discloses a gas chromatograph for analyzing unit modularization, which comprises a column box, a detector (4), a sample injector (3), a chromatographic column (14), an air channel assembly (7) and a motor assembly (9). The column box is composed of a front column box (11) and a rear column box (10) which are separable, wherein, the front column box (11), the detector (4), the sample injector (3) and the chromatographic column are fixedly connected into an integral analytic unit module; the rear column box (10), a heater, the air channel assembly (7) and the motor assembly (9) are fixedly connected into an integral temperature program-control module with a rear door; the lower ends of the front column box and the rear column box are respectively provided with a column box fixing bar (12). The utility model can shorten the time of replacing the chromatographic column, the detector and the sample injector aiming at various samples and can shorten the time of debugging the chromatograph, and therefore, the work efficiency is increased. Moreover, after replaced, the detector can still keep fast stability and reproducibility, and the detector is not easy to pollute and damage.
Description
Technical field
The utility model belongs to the gas chromatograph that a kind of laboratory is used, and relates in particular to the post box structure of the gas chromatograph of using in a kind of laboratory.
Technical background
In the gas chromatograph that existing laboratory is used, its post case (comprising electric motor fan that the well heater, air bath of the control of post oven temperature, stir, air channel etc.) is loaded onto injector and 1～4 detecting device, manufactures fixing one-piece construction.And the key core in the gas chromatograph analytical technology partly is: chromatographic column, injector (or claiming vaporizer) and detecting device, this is three vitals that can direct decision do sample analysis, often will select, change different chromatographic columns, injector and detecting device at different samples in the practical application.Present many units often will bear the test analysis repeatedly of several samples, but owing to gas chromatograph in the prior art is a post case one-piece construction, need carry out demolition and replacement in the post case chromatographic column, injector and detecting device are relatively wasted time and energy; Chromatograph can not keep strict conformance to the test condition repeatedly of same class sample after changing, when especially using ECD (electron capture detector) instead behind the chromatograph use FID (flame ionization ditector), injector is also wanted disassembly, cleaning, aging, thereby chromatograph must be debugged 2～3 days ability and normally move work, the waste extensive work time; If multiple detecting device is contained on the post case together do not used, also pollute easily and damage; The post case inner bag of existing gas chromatograph is a cube structure in addition, exists 4 heat transfer dead angles, and the temperature control precision in post case space can not improve, the temperature field skewness.
Summary of the invention
The utility model technical issues that need to address provide the modular gas chromatograph of a kind of analytic unit, use the modular gas chromatograph of this analytic unit can shorten greatly because of needing replacing chromatographic column, detecting device, injector at different samples and debugging the chromatographic time, improved work efficiency, and detecting device is changed this gas chromatograph of back can also keep stability and repeated fast, and detecting device also is difficult for polluting and damaging.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The modular gas chromatograph of a kind of analytic unit, it includes post case, detecting device, injector, chromatographic column, ducting assembly and electric machine assembly, described post case is made up of separable front pillar case and rear pillar case, front pillar case, detecting device, injector and chromatographic column are connected and make incorporate analytic unit module, rear pillar case, well heater, ducting assembly and electric machine assembly are connected and make incorporate back pullout (BPO) programmable temperature module, also are provided with post case fixed strip in the lower end of front pillar case, rear pillar case.
The inner bag of described forward and backward post case is a cylinder-like structure; Described detecting device can be flame ionization ditector or is electron capture detector, thermal conductivity detector (TCD), flame photometric detector (FPD), catalytic detector, nitrogen phosphorous detector.
Owing to taked above-mentioned scheme, the advantage that the utility model is compared with prior art had is:
1, because the modular gas chromatograph of the utility model analytic unit adopts the front pillar case and the rear pillar box structure of separable dismounting, therefore use this gas chromatograph can shorten greatly, improved work efficiency because of need to change the time of chromatographic column, detecting device, injector at different samples.
2, because the utility model is made the integrated analysis unit module with vitals chromatographic column, detecting device, injector in the gas chromatograph, when changing, only need the replacement of whole unit module is got final product, because be integral replacing, therefore need not debugging after changing just can use, save the working time, and do not had influence on chromatographic job stability and repeatability; Ought not use a certain analytic unit module in addition, this analytic unit module can be positioned over the place of dried and clean, so detecting device is not easy to pollute and damage.
3, because the front pillar case inner bag of the modular gas chromatograph of the utility model analytic unit is a cylinder-like structure, improve post oven temperature, control precision greatly, uniform distribution of temperature field has been accelerated the warming and cooling rate that the post case heats up.
