Description
Technical field
The utility model is related to a kind of Cr VI automatic measurement systems using micro- reaction chip.
Background technology
Chromium is a kind of argenteous hard metal, is mainly occurred in the form of three kinds of crome metal, trivalent chromium and Cr VI, is owned
The compound of chromium is all toxic, and wherein Cr VI toxicity is maximum.Cr VI is the property swallowed poisonous substance/extremely toxic object of imbedibility, and skin connects
Sensitivity may be led to by touching；It is more likely to that inherited genetic defects, sucking is caused to be potentially carcinogenic, has lasting danger to environment.Harm
Maximum is to have carcinogenic danger when contacting or suck in long or short term.
But conventional method measures Cr VI at present, after saying that sample reaches stable state with color developing agent hybrid reaction,
Using photometer measurement, the reaction time is long, artificial to add sample there are errors larger, measurement result larger using sample size
It is uncertain larger.
Utility model content
For the above demand, the utility model provides a kind of Cr VI automatic measurement system using micro- reaction chip, tool
It is reduced reagent consumption, reaction speed is fast, the advantages of improving sensitivity and the detection limit of detection.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：
A kind of Cr VI automatic measurement system using micro- reaction chip, including three syringe pumps, three syringe pumps it is defeated
Enter end and be separately connected color developing agent pipeline, sulfuric acid pipeline and sample inlet, output end connects mixed block, is connected in turn after mixed block
Peristaltic pump, micro- reaction chip and trace circulation pond, trace circulation pond side are provided with photoelectric detection system, and the other side is equipped with monochrome
Light injects trace circulation pond.Three syringe pumps are respectively by color developing agent pipeline, sulfuric acid pipeline and sample inlet by color developing agent, sulfuric acid
With sample intake line system, and it is driven to flow into mixed block, then by peristaltic pump is pumped into the reaction liquid in mixed block
Micro- reaction chip, reaction reach balance and exit into trace circulation pond from chip, so that monochromatic light is injected trace circulation pond, use light
Electric detection means can measure the absorbance value of sample in trace circulation pond, to calculate the content of Cr VI in sample.
Preferably, the monochromatic light is generated by light source by monochromator.
Preferably, trace circulation pond side is provided with waste collecting device, the sample solution after detection is flowed into
To being focused in waste collecting device.
Preferably, the photoelectric detection system includes photometer, the absorbance value of sample in flow cell can be measured.
The utility model has the advantage of：The utility model uses the accurate sample introduction of syringe pump, is made using micro- reaction chip
For reaction vessel, reagent consumption is reduced, reaction speed is fast, improves sensitivity and the detection limit of detection.
