2. Product parameters

1. Detection line (DL): As, Se, Pb, Bi, Sb, Te, Sn＜0.01µg/L
Hg, Cd＜0.001µg/L
2. Precision (RSD) ＜0.7%
3. Linearity range: more than three orders of magnitude.

3. Product features

1. The new single-pump four-channel injection and waste discharge system is adopted to shorten the length of the pipeline, enhance the reaction stability, and realize the switching between continuous injection and intermittent injection sampling. 

2. It can measure three elements at the same time to improve the analysis efficiency of the instrument.

3. Light source system: The high-performance hollow cathode lamp adopts the pulse modulation/constant current drive power supply mode, which improves the emission intensity and efficiency of the hollow cathode lamp and prolongs the life of the hollow cathode lamp.

4. The high-performance hollow cathode lamp adopts coding technology, the instrument can automatically identify the hollow cathode lamp, and at the same time can record the use time of the cathode lamp to effectively monitor the use of the instrument.

5. Detection system: Hamamatsu solar blind photomultiplier tube is used, which has the characteristics of high signal-to-noise ratio and stable performance.

6. The light path adopts a shielded short focal length light path, which effectively reduces the energy loss in propagation.

7. Adopting a closed double-layer quartz atomizer, the atomization temperature can be adjusted, which can effectively reduce the liquid phase interference, reduce the memory effect, and at the same time improve the atomization efficiency.

8. Hydrogen flame observation window, which can observe the flame combustion state in real time.

9. The software can perform statistics on data to facilitate users' needs for data statistics.

10. The instrument host can be upgraded for morphological analysis.

11. Single pump four-channel sample injection, sample injection and waste discharge are carried out at the same time, which can maintain the constant pressure reaction system and enhance the stability of the system.

12. Data processing system:
(1) Multi-window menu software design, convenient for customer operation requirements
(2) Switching between offline and online modes can be realized.
(3) Real-time display of data signals.
(4) Various data results can be switched and displayed at will.
(5) Provide the saving and calling of test methods to reduce the method establishment time.
(6) Data can be output as files in any format.
(7) The software has the function of role rights management, which is designed based on the audit trail function framework. The data structure is based on the database schema for easy integration.
(8) The system has fault codes, and the software can be upgraded to remote instrument fault diagnosis.
