Flame and graphite furnace Atomic Absorption Spectroscopy

AAS series is PC-controlled through USB2.0 interface, with data can be automatically processed; it has multiple protective measures to ensure safe and reliable operation; simple and convenient structure design combined with user-friendly software interface simplify operation.

 

AAS 6000 Flame Atomic Absorption Spectrometer

Flame atomic absorption is applied to micro and trace metallic elements test, covering over 30 elements. The instrument has simple structure, provides fast test, with good repeatability and less interference, especially suitable for testing Cu, Zn, K, Na, Au, Ag, etc.

 

AAS 9000 Integrated Flame and Graphite Furnace Atomic Absorption Spectroscopy

It has flame and graphite atomizers, incorporating their features. Users can switch atomizer quickly based on test needs to ensure best test effect.

AAS 9000 (with graphite furnace auto sampler) and adopt flame and graphite atomizers, with better universality. In serial light path design, it realizes automatic switch between two atomizers, and delivers stable and reliable test.

 

Features

Host Machine

1、Total reflection achromatic optical system

Using concave mirror instead of convex lens, effectively solved the chromatic aberration problem of different focuses of different elements, and increased the efficiency of optical system.

2、C-T Monochromator

1800 lines/mm, blaze wavelength of 230nm beam-splitting system

3、8-element lamp turret

8 independent lamp power supplies, 7 lamps heating simultaneously at most while one is working, saving lamp changing and preheating time, the operation is more convenient as a result.

4、Full automatic design

The instrument is totally monitored and controlled by computer, except for mainframe power switch.

5、USB2.0 communication interface

Update the old RS232 mode into the latest USB2.0 mode, increasing the communication speed, and compatible with the new operation system.

6、Background correction system

Deuterium lamp background correction and self-reversal background correction, be able to correct over 30 times of background when background signal is 1A

7、Streamline sheet metal process design, modern stylish, elegant and beautiful

8、Proprietary intellectual property rights and powerful activity manager software

Humanized operation interface makes your operation easier; the interface of the software can be switched between English and Chinese. Full automatic qualitative and quantitative analysis can calculate element contents and generate report automatically.

 

Flame System

1、Pure Ti atomizing chamber and burner

Prevent acid gas corrosion effectively and maximize service life

2、Efficient glass nebulizer

Efficient glass nebulizer with higher nebulization efficiency, easy to maintain and replace

3、Mass flow controller makes the flow of C2H2 controllable

Control C2H2 flow adjustable, monitoring the flow dynamically, ensuring it to be convenient and safe.

4、Multiple safety protection measures, ensuring the reliability of the sample analysis

(1)C2H2 leaking preventive measure 

(2)C2H2 pressure monitoring

(3)Air pressure monitoring

(4)Burner monitoring

(5)Flaming burning monitoring

(6)Water seal monitoring

 

Graphite Furnace Atomic Absorption Spectroscopy System

1、Internal power supply 

The power supply of graphite furnace and host machine are incorporated in one instrument, which makes it more compact, shortens cable length, reduces the electromagnetic interference of graphite furnace power supply and improves heating efficiency of graphite tube.

 

2、High temperature control precision, quick temperature rise

Large power transformer, micro resistance cable and light control heating mode are used, combined with software and hardware temperature calibration systems, ensuring ±1% control precision under high temperature

 

3、Multiple safety protection measures, ensuring the reliability of the sample analysis

1)Cooling water flow monitoring

2)Carrier gas pressure monitoring

3)Graphite tube temperature monitoring

4)Graphite furnace temperature monitoring

 

4、Carrier gas flow auto-control

The internal and external gas of graphite furnace are automatically controlled by computer based on software heating procedures.
