characteristic:

1. Fully automatic measurement of four lamp positions

It can achieve simultaneous preheating of four lamps, improve stability and work efficiency, save sample and reagent usage, and significantly reduce detection costs. By using dual injection pumps to extract samples and reducing agents, the sampling accuracy is improved, ensuring the consistency of steam reactions, and the precision and accuracy of test data are guaranteed. The amount of reducing agent can be precisely adjusted according to the actual acidity of the sample, to find the reaction conditions for steam reaction, enhance the fluorescence signal intensity, and better meet the requirements of trace and ultra trace element analysis.

2. Patent for a sequential injection steam generation system ZL 2012207399837

1) The newly designed flow path system isolates reagents from each other, greatly reducing diffusion mixing effects and improving sensitivity and stability;

2) The device is simple, avoiding frequent leakage caused by sample crystallization and wear, eliminating potential faults, improving system reliability, and saving user maintenance costs;

3) The flow path technology adopts a new working method, where the reagent does not come into contact with the valve body of the clamp, with a lifespan of up to 500000 cycles, and ensures that the flow path system is free of residue, dead volume, and cross contamination.
