Automatic gas flow adjustment during change over between Air/C2H2 and N2O.



3 flame systems are available. Air/acetylene is the standard configuration with the N O/acetylene and Air/LPG as options.



• This flame uses a 100mm single slot burner for standard configuration.

• The high sensitivity (Cu 5ppm > 0.9A) is due to the efficiency of the fixed position High Efficiency Nebuliser fitted as standard. An acid resistant replacement is available as an option.


N O/Acetylene

• The burner for this gas has a 50mm slot and is used to measure elements less prone to ionization such as: Aluminium, Tin, Titanium, Calcium and Vanadium.

  - The switchover from air/acetylene and flame off is fully computer controlled.    


Air/Propane (LPG)

• This flame uses a 3 slot burner and with the low pressure requirement it is also much safer to operate. Due to the lower temperature it is ideal for analysing alkali metals such as Potassium, Sodium and Lithium, especially when used in the Emission mode.

• There are some remote areas in the world that have difficulty obtaining acetylene or even a high enough purity to operate the flame, so LPG can give a real alternative and offer comparable results throughout the wavelength range.


Safety Features

• Gas Pressure Monitoring for all gasses • Burner Identification • Flame Sensor • Drain Trap level Sensor • Gas Leak Detector

• Safety cut off switch



The graphite furnace atomiser is available in 2 Models:

- In the AA8000G instrument the graphite furnace head is fixed into the light path.

- In the AA8000FG instrument the graphite furnace head is positioned automatically into the light path by a simple operation in the AA-Win software.

Furnace Head Design

- The Transverse head is heated and cooled efficiently due to the feedback system and has been designed to reduce analytical problems normally associated with this type of technique.

- Pyrolytically coated graphite tubes are used as standard and are manufactured to improve performance as well as increase the analytical life.

- Platform Tubes are supplied as standard and will accept volumes up to 20μl.

Heating Program

- Up to 10 heat stages are available. These can be set up and stored in the AA-Win software.

• The graphite furnace tube is cooled efficiently by an optional water circulation system / chiller.

Continuous Flow Hydride Analysis System

Main Features

• Improved detection limits for inorganic Hg

• RSD ≤ 2%

• Easily adapted to standard hydride mode with improved detection limits for As, Se, Sb and other hydride forming elements via a heated cell

• Improved stability: The micro peristaltic pump is controlled via AAHyd-Win creating a stable flow of sample and reagent and producing a stable formation of H2 gas and hydrides

• Compact system the smallest footprint of its kind on the market

(95mm x 118mm x 140mm)

• Chemically resistant: ceramic pins, PFA mixing block, and quartz glass





Flow Injection Hydride Generator

Main Features

1. Unique pneumatic automated technology such as auto-sampling system, automatic fluid measurement system, flow stabilizer (instead of the peristaltic pump), program-time controller and so on are pneumatic automatic systems which are run by the carrier gas source pressure. Many performances are superior to those of the electric systems.

2. Highly Automatic: After pressing the start key, the whole process (sampling, reacting, calibrating and cleaning) will be finished automatically. Automatically reading is possible when connecting with the main unit (if the main unit has the function)

3. Unique electric quartz absorption tube (atomizer): compact (can be used in the Zeeman AAS), speedy temperature rising, easy installation, and stable temperature. The lifetime of this tube is 10 times longer than the flame tube. As long as the temperature lowers down, the analysis method can be changed.

4. Superior performance (sensitivity, detection limit, stability, efficiency): the sensitivity of most elements is better than 1ng/ml/1%A. For example, the sensitivity of Arsenic is better than 0.15ng/ml/1%A. Relative standard deviation (RSD) is lower than 3%. The single measurement will take 25 to 35 seconds.

5. High adaptive: the hydride generator can be used on all the old models of AAS

6. Good reliability: low failure rate, seldom consumables.

7. Small footprint: width*depth*height = 20.5(cm)*15(cm)*12.5(cm); weight = 1.5 kg.

8. Multiple readings: peak height reading (recommended), peak area reading, continuous reading are possible

9. Less solution: sample 2-2.5 mL (including clean). potassium borohydride 1-1.5 mL, carrier liquid 5-6 mL

10. High performance lamps for hydride elements (e.g. Pb, As, Hg, Sb & Bi)
