Atomic absorption spectrophotometer AAS6000 series

Product Description, Technical Parameters, and Configuration

Instrument Introduction

The AAS6000 series atomic absorption spectrophotometer is a fully automatic and intelligent flame atomic absorption instrument developed by Tianrui Instrument Company based on years of research and development experience. It is used to determine the content of constant, trace, trace metal elements and semi metal elements in various substances. The machine adopts a PC and Chinese interface operation software, making the instrument operation simple, intuitive and easy to understand. By utilizing advanced electronic circuit systems and USB 2.0 communication control, the instrument has achieved automatic adjustment of functions such as wavelength scanning, peak positioning, spectral passband width, rotating element lamp holder, atomizer height and position, gas flow rate, lamp current, and negative high voltage of photomultiplier tubes. The instrument stores the analysis operation reference conditions for all measured elements of multiple analysis methods. Users can also modify the operating conditions as needed, and save the operating conditions, working curves, and test results in a file, which can be retrieved for use and processing.

Performance characteristics

1. Total reflection achromatic optical system.

The use of concave mirrors instead of convex lenses as optical focusing devices effectively solves the problem of chromatic aberration caused by different focal points of different elements and improves the efficiency of the optical system

2. Fully automated design.

Except for the host switch, all instrument functions are automatically monitored and controlled by a PC

3. Eight element lighthouse.

Working with one lamp, seven lamps can be preheated simultaneously, saving time for lamp replacement and preheating, making element measurement faster and more convenient

4. USB 2.0 communication method.

Eliminated the old 232 serial communication method, adopted the latest USB2.0 communication interface, improved communication speed, and compatible with the latest computer systems

5. Pure titanium atomization chamber, pure titanium combustion head.

Effectively preventing acid gas corrosion and increasing service life

6. Efficient glass atomizer.

Adopting a specially customized Wu's high-efficiency glass atomizer, the atomization efficiency is higher and the versatility is strong

7. The quality flow controller realizes acetylene flow control.

Continuously adjustable acetylene flow rate and dynamically monitored flow rate, easy to use, safe and reliable

8. More security measures to make sample analysis safer and more reliable

(1) Acetylene leakage protection

(2) Acetylene pressure monitoring

(3) Air pressure monitoring

(4) Explosion proof switch status monitoring

(5) Flame combustion state monitoring

9. Background correction system.

Deuterium lamp background correction: capable of correcting 1A background.

Self absorption background correction: capable of correcting 1A background.

10. The appearance adopts streamlined sheet metal process design, simple and fashionable, beautiful and generous

11. Independent intellectual property rights, powerful and comprehensive analysis software.

The user-friendly interface makes your operation easy. The Windows operating system automatically switches between Chinese and English, with fully automatic qualitative and quantitative analysis, automatic calculation of element content, and automatic generation of test reports.
