Which Things to Know in Buying an AAS?
If you intended to comply with the relevant regulations, and to purchase a flame type atomic absorption spectrometer, it would be better to refer to the standard, "NIEA M111.01C", which is issued by NIEA Taiwan, and follow up the suggestions in the document.
The equipment you need for a complete include: FAAS, burner head, hollow cathode lamp, graphic display & recorder, pipette or micro-pipette, valves, analytical balance.
ACTTR Technology recommends a good combination, one-stop shopping for you. Not only allows you to meet the NIEA M111.01C specifications, as well as a good performance/price ratio, and you can own a flame with graphite furance combination type AAS, with auto switch function between FAAS and GFAAS in 2 seconds.
Atomic Absorption Spectrometer
AA-7020 standard version, a single-beam atomic absorption spectrometer (short optical path design, even for arsenic, selenium, also has a very low detection limit), with elements of light + deuterium lamp (for background removal), dual frequency light sources.
In the AA-7020 optical system design, not only with adjustable slit and photomultiplier tube, which can detect the wavelength range, but also a wider range of wavelength, than the normal, 190-900 nm.
AA-7020 has been configured with both flame and graphite furnace space inside the body in the mechanical design. Fully equipped complete functions of AAS at once, and you do not have to worry about the future requirment and purchase and set up the equipment again. Both the furnaces can be switched within two seconds, manually or automatically, calibration unnecessary, after switching, the experiments can be carried out immediately.
With AS-600 common type autosampler (for both flame & graphite furnace), executes the automatic wavelength selection, automatic changing slit, automatic switching element lamp, automatic switch on/off deuterium lamp, automatically switches atomizer, after necessary parameters are set up for each sample. Reach objective analysis of various elements automatically, far more than the definitions in NIEA M111.01C.
Burner Head
AA-7020 burner head and the spray chamber, the entire furnace are made by titanium metal. It is casting, durable, with long life. The burner monitoring function, can avoid wrong burner type is used while the nitrous oxide is applied.
Hollow Cathode Lamps
AA-7020 can be installed with six hollow cathode tubes, switch it, once only a sample of a single element lamp exposure after atomized.
Graphic Display and Recorder
AA-7020 free PC application software, powerful, not only with graphical display and a detailed record function - records the offset, atomic incompletion, leakage carbonization process, sensitivity, peak signal and so on. Also designed for exclusive features designed QC quality control, the whole sample group records can be stored by the parameters of standard deviation (SD), the relative standard deviation (RSD), the correlation coefficient, baseline drift, sensitivity correction, the sample cap, and more.
Pipette or Micro-pipette
We have all kinds of pipette (quantitative straw) or micro pipette (micropipette) with various capacities pipette tip available for purchasing.
Valve
We can set up the double meter gas valve for you, while the AAS is installed. Depending on your purchase order & experimental requirements, we can configure brass or stainless steel valve for you.
Analytical Balances
ACTTR Technology has a variety of analytical balance, satisfied with the definition of 0.1mg weighting accuracy in NIEA M111.01C.
ACTTR Technology also provides the related service of laboratory planning, equipment installation, on-site performance testing, after-sales maintenance, accessories, supplies, spare parts and other services, please contact to us for more information.
