The product adopts air source sequential flow injection technology, dual-beam optical structure and information sample management system, which solves the problem of poor durability of peristaltic pump, improves the problem of poor stability of super-measurement analysis instrument, and realizes the technical construction mode of atomic fluorescence product without peristaltic pump maintenance and dual-beam calibration.
* Maintenance-free
1. The pneumatic flow path system without wear parts can get rid of the maintenance troubles of peristaltic pumps.
2. The syringe adopts pure water medium, which solves the damage problem of measuring instruments caused by acid and alkali solution.
Non-adjustable type
1. Plug and play element lamp technology, without manual adjustment, good consistency of lamp position and reliable detection results.
2. The height of atomizer of Shi Ying furnace is automatically set to the working area, without visual adjustment, which is convenient and quick.
It is more stable
1. Double-beam single detector optical system can effectively deduct the drift and fluctuation of excitation light source, and has good stability in mercury test.
2. Pneumatic flow path system, the deviation of constant pressure and constant current injection is small, and the difference of long-term test of the same sample is small.
3. Online, reverse and multiple cleaning can be realized, with small sample residue and the highest concentration can be tested.
4. Vapor-liquid separator, refrigeration and water removal, stirring and mixing evenly to improve sensitivity.
It is more environmentally friendly
1. The waste gas closed diversion technology is adopted, and the waste gas is discharged outdoors after adsorption treatment through the diversion channel to ensure the safety and environmental protection of the analysis work.
2. The waste liquid is stored in a closed way, which reduces volatilization, has overflow alarm and is safer to use.
More applicable
1. It can quickly connect morphology analysis units to form atomic fluorescence morphology analyzer.
2. It can be connected with trace element test accessories with large injection amount to meet the test of ultra-micro content samples of users.
3. Micro-injection accessories with small injection amount can be connected to meet the needs of users for small injection amount of rare samples.
