Name of Instrument: Atomic absorption spectrophotometer

Type and Specification:Agilent 240 DUO

Manufacturer:Agilent

Purchase Time: 2014

Main Uses: It is to detect the major element and the poisonous and harmful heavy metal. It is equipped with flame and the main engine of graphite furnace.

Main Technical Indexes:

1. It is designed with the narrow beam, with the fully sealed non- lens and total reflecting optical system, and the optical component applies the quartz coating;

2. It applies the rotation Beam Combiner( RBC);

3. The optical base with full cast aluminum is a special anti- earthquake design;

4. It applies the Czerny-Turner monochromator;

5. Wavelength range: 190~900 nm

6. Wavelength scanning speed: 2000 nm/min;

7. Automatic slit handover has grades covering 0.2、0.5、1.0 nm and high- low grade;

8. It has fixed 8 lamp holder, rotating mirror, which provides convenience to automatically and quickly choose element lamps;

9. It applies the quick multi- element sequential scan in the flame part, which can complete multiple elements determination;

10. The nebulizing system is made up of fluoroplastics, and the hoist capacity of the atomizer solution is adjustable;

11. The burner head is made of Incoloy alloy, and the base is attached to Teflon anti- corrosion shielding film which has a good anti- blocking effect and is suitable to the analysis of high salt samples;

12. Glass impact bead;

13. Double- end spoiler;

14. Safety interlock monitor;

15. Wide range photomultiplier can get the maximum signal- to- noise ratio;

16. With the high intensity deuterium lamp background correction, it can be corrected to the background of 2.5 Abs, and the response time is 2 ms, and it has the automatic damping adjustment function;

17. The absorbance value of 5 ppm copper is larger than 0.9 Abs, and the precision RSD is less than 0.5%;

18. The temperature of graphite furnace is controlled precisely, and the Zeeman magnetic field has multiple grades which are adjustable;

19. Control technology of stable temperature area: in the range of 40- 3000°C, it can implement the heating programming with the maximum heating speed 2000 ℃/s;

20. The graphite furnace applies the dynamic feedback system of temperature( CTZ), and the precise temperature control makes the graphite furnace high precision and low memory effect;

21. It has the multipoint curve fitting to simulate the background absorption curves;

22. The Zeeman deducting background response should be less than 5 ms;

23. The Zeeman background correction can meet the background absorption of 2.5 Abs in the whole wavelength range of 185~900 nm;

24. Characteristic mass: Cd 0.2 pg;

25. It is equipped with the graphite furnace autosampler;

26. It has color camera system;

27. Volume of sample injection: 1-70μL.
