8. with argon hydrogen flame observation window, the flame state can be monitored in real time.
9. the circuit system adopts strong and weak current separation and high integrated function card circuit structure.
10. dedicated Windows7/8 system operation software, with powerful expert online help system.
11. the software can realize the rapid import of measurement data into EXCEL and realize the sharing of network resources.
1. realize four lamp position, double injection pump and double channel automatic measurement:
The four lamp can be preheated at the same time, at the same time, at the same time, any two elements are tested, the stability is improved and the working efficiency is improved, the amount of samples and reagents is saved, and the detection cost is greatly reduced. The sample and reducing agent are absorbed by double injection pump to improve the precision of sampling, to ensure the consistency of steam reaction, and to ensure the precision and accuracy of the test data. The amount of reducing agent can be adjusted accurately according to the acidity of actual sample, find the best reaction condition of steam reaction, enhance the intensity of fluorescence signal effectively, and meet the analysis demand of trace and ultra trace elements better.
2. the latest patent sequence injection technology
1) the newly designed flow path system, the separation between the reagents, greatly reduces the diffusion mixing effect, and improves the sensitivity and stability effectively.
2) through the coordination and coordination of the pinch valve and the double injection pump, the complex multi channel valve and the injection pump flow instrument function can be realized. The device is simple to avoid the frequent leakage caused by the sample crystallization and wear, to eliminate the hidden trouble, improve the system reliability and save the maintenance cost for the users.
3) flow road technology has taken a new way of working, the reagents do not touch the valve valve body, life span is 500 thousand times, and the flow system has no residue, no dead volume, no cross pollution.
3. the syringe is made of special material and is exclusively customized to solve the problem of syringe leakage caused by alkaline solution corrosion.
4. the original imported injection pump has high reliability and the accuracy of injection is less than 0.05%. The automatic injector adopts advanced slide rail design, the motion mechanism adopts a large number of imported linear slide rail, self lubrication, self cleaning, and maintenance free. It realizes the super quiet high speed work, and the positioning is accurate and the structure is reliable.
