Product details
1. Suitable for trace analysis of elements such as arsenic, mercury, selenium, antimony, etc. in samples.
2. Simultaneous measurement of two elements in two channels results in shorter measurement time for a single sample.
3. Coordinate sampler, supporting three types of sample disks: 69 position 25mL/134 position 15mL/183 position 10mL.
4. Pinch valve application technology, replacing traditional one-way valves and multi pass valves, avoids reagent contact with the valve body, has no corrosion, no memory, high reliability, and a lifespan of over 500000 times.
5. The instrument has single point configuration working curve, automatic dilution, and fully automatic measurement functions.
6. Sample/current isolation technology to eliminate the influence of diffusion effects on measurement results.
7. A specially designed shielded quartz furnace low-temperature atomizer reduces fluorescence quenching and gas-phase interference, improving atomization efficiency.
8. Adopting a new closed two-stage gas-liquid separation device, there is no need to add liquid or discharge waste.
9. High performance coding hollow cathode lamp, instrument automatic recognition, can monitor service life.
10. The gas system adopts an array structure and is equipped with a new type of throttle device to save argon gas consumption.
11. The instrument has functions such as power on self-test, automatic diagnosis, and automatic fault alarm.
12. The argon hydrogen flame observation window is designed to monitor the flame status in real time.
13. The circuit system adopts a highly integrated functional board card structure that separates strong and weak electricity.
14. The software is compatible with Windows 7/8/10/XP systems and has a powerful expert online assistance system.
15. Quickly import software data into EXCEL to achieve network resource sharing.
16. Reserve various upgrade interfaces such as morphological analysis, Hg, Cd electric evaporation devices, etc. to meet users' more functional needs.
characteristic:
1. Simultaneous measurement of two elements in two channels.
2. The use of two channel merging technology has increased the intensity of atomic fluorescence signals, further improving the detection limit of the instrument.
There has been a significant improvement in ultra trace analysis, thereby increasing the detection limit.
3. Adopt a dedicated peristaltic pump with ten rollers, six channels, and each channel can be independently adjusted.
4. Adopting a newly designed cyclone gas-liquid separation device, the chemical reaction is more complete and the gas-liquid separation effect is better.
5. Adopting a new closed two-stage gas-liquid separation device, there is no need to add liquid or discharge waste.
6. It can be upgraded to a liquid chromatography atomic fluorescence spectrometer for the analysis of element forms and valence states.
