China Bnaas-B4530g Atomic Absorption Spectrophotometer

Features:

1. Completely controlled by PC, can flflexibly select the flflame and graphite furnace atomizer (optional).

2. Integrated flfloated optical platform design can obviously improve the optical system shock resistance and keep stable though

use the optical signal for a long term.

3. Eight light stands can be changed automatically and preheat the eight lights meantime as well as optimize the working condi

tion of the hollow cathode lamp.

4. Position adjusting: the best height of the flflame burner and can automatically set the front and rear positions.

5. Fully automated wavelength scanning and peak searching.

6. Complete safety chains protection equipment: the function of warning and automatic safety protection towards the wrong

burner, leakage of the gas, under voltage of air and the abnormal flflameout.

7. Deuterium lamp and self-absorption background regulation

8. Data processing: super strong database, possesses more than 500 data self-storage and cut-off storage function, can store

the analyzed result with the form of EXCEL and the testing method and the result can be randomly called.

9. Measuring method: flflame absorption method and emission method.

10. Result printing: parameter printing, data result printing and diagram printing

Advanced graphite furnace temperature controlling technology

1.The bringing in of PID technology can effectively overcome

the inflfluence on the temperature rising process caused by the

voltage flfluctuation and the resistance change to make more

accurate controlling process. The combination of the

3ms/time fast sampling technique can make more accurate

and reliable testing data

2.The fast heating capacity can improve the flflexibility of the

elements further

3.Use the ordinary power source of 220V without need of

dynamic power of 380V

4.The maximum procedure heating capacity setting of 20

levels can make a more convenient and easier test of different

samples

5.Three grades adjustable gas flflow can accustom to more

application needs

6.Can timely alarm when the gas and water is stopped and

insufficient gas and water, can avoid the equipment damage

and measuring error

Safe, reliable and convenient flflame system

1.EPC can control the flflow of Acetylene (C2H2) more accurate

ly and it is a kind of system which also can operate easily

2.Efficient atomization system enables a higher sensitivity

3.The whole operation system has a high security as the fire

safety system can alarm whenever the electricity is cut off,

abnormal flflame occurs, a lack of pressure happens or the

burner does not match well. And it will automatically turn off

the gas, prohibit tempering. Thus it keeps the operation people

and equipment from harm and damage.
Multi-functional software workstation

1.A workstation that is supported WINDOWS 7

2.The rich menu brings great convenience to the use of

customer

3.Convenient conversion between different menus makes the

operation more easily

4.Various analytical correction methods provide the users

more choices

5.Basic default parameter settings enable even the beginners

can do the normal operation

6.Flexible storage, editing and printing methods give the user

largest support
