AA320N Atomic Absorption Spectrophotometer

COMMON FEATURES

1. Build-in computer data processing and LCD display: stable and reliable with the functions of integral holding, peak height and area, auto zero adjusting, deuterium lamp background correction, multi-linear and nonlinear curves fitting, various parameters and working curves displayed in screen and report printing, etc. It is equipped with interface for externally linking PC.

2. Stability: Double-beam system can automatically compensate the light source drift and wavelength drift caused by the variation of temperature (with the function of the eliminating the affection of wavelength drift on the base line stability) and electronic circuit drift so as to reach a good basic line stability.

3. Quickly: The cathode lamp needs not be pre-heated for long time and sample can be analyzed immediately. It is the preferable instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of samples.

4. High precision of measurement: Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration.

5. High energy optical path: A total reflection system is adopted to eliminate color difference in full range. By means of chemical conversion, a round light spot of the light source becomes a long light spot, which enters into the slit. Therefore the light flux of double beam is enhanced.

6. Long-life and anti-corrosive atomization system: The burner is made of new type titanium alloys, anti-corrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.

7. Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation.

8. Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used to analyze air-acetylene flame as well as nitrous oxide-acetylene flame and extend the analytic elements to reach more than 60.

9. Complete set of accessories: to be supplied with the instrument and ready for use after they are purchased.

CHARACTERISTICS

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

2. Integrated floated 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 condition of the hollow cathode lamp.

4. Position adjusting: the best height of the flame 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 flameout.

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: flame absorption method and emission method.

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

COMPLETE AUTOMATIC CONTROLLING SYSTEM

With the help of the software, the following can be easily achieved

1. Selection of the element lamp

2. Up-down-front-rear adjustment of the lifter

3. Adjustment of the optical energy

4. Selection of the slit

5. Determination of wavelength scanning and peak searching

6. Selection of the atomizer

7. Setting of the background deduction method

8. Controlling of the gas flow

9. Automatic flaming and flaming out

10.Setting of the graphite furnace testing method

ADVANCED GRAPHITE FURNACE TEMPERATURE CONTROLLING TECHNOLOGY

1. The bringing in of PID technology can effectively overcome the influence on the temperature rising process caused by the voltage fluctuation 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 flexibility 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 flow 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 FLAME SYSTEM

1. EPC can control the flow of Acetylene (C2H2) more accurately 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 flame occurs, a lack of pressure happens or the burner does not match well. And it will automatically turn off the gas, prohibit temper ing. Thus

it keeps the operation people and equipment from harm and damage.

MULTI-FUNCTIONAL SOFTWARE WORKSTATION

1. A workstation that is supported WINDOWS XP/2000/NT

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
