Modeling 1 174? 440? 358mm (length? Wide? High)? Weighing about 80 kilograms

technical characteristics

1, two channels simultaneously measure two elements, which improves the analysis speed of the instrument. ?

2. With the newly designed high-efficiency cyclone reaction separation device, the chemical reaction is more complete and the sensitivity of the instrument is significantly improved. ?

3. The hollow cathode lamp adopts a new pulse modulation and constant current driving power supply mode, which improves the emission intensity and efficiency of the hollow cathode lamp and prolongs its service life. ?

4. It adopts a brand-new gas path design, which can automatically cut off the gas source when it is turned off, saving argon consumption. ?

5. The hollow cathode lamp adopts coding technology, and the instrument automatically identifies the hollow cathode lamp. ?

6. Double peristaltic pump intermittent flow sampling device is adopted to save sample consumption and avoid cross-contamination between sample and blank. ?

7. The instrument can configure the working curve at a single point and automatically dilute high-concentration samples. ?

8. An automatic sampling system with 130 sample positions ensures the sampling accuracy of samples. ?

9. The software can realize automatic gas monitoring and diagnosis, and cut off the gas source in real time. ? 10, with real-time observation window of argon-hydrogen flame. ?

1 1, the motherboard adopts strong and weak current separation to reduce cross interference. ?

12. Closed timely atomizer is adopted. ?

13, low-temperature atomization ignition device, to improve the stability of the instrument. ?

14, adopting RS-232 serial communication. ?

15. The data can be sent to EXECL for real-time analysis. ?

16, the software has online help function and management sample correction function.
