AED IIIJoint Analytical Systems
The JAS AED is the only commercially available atomic emission detector (AED) for gas chromatographie. It lets you detect virtually all elements within any volatized compound (except helium, the carrier gas) at picogram-level sensitivities, with excellent selectivities. The JAS AED transports sophisticated research capabilities into a reliable, cost effective instrument that is easy to use and maintain - ideal both routine QA/QC and research laboratories.
The AED III in detail
The AED III uses atomic emission spectroscopy to detect elements in compounds eluting from a gas chromatograph. A helium plasma fragments all compounds with the excited atoms, producing characteristic emission lines of light. A lens focuses the light onto the entrance slit of the spectrometer. A high resolution flat-field grating, which is a concave grating, images the elemental light spectrum from 160-209 nm on a flat plane back-thinned CCD.
C, N, O
P, Si, S
As, Hg, Se
Customized solutions for other elements, e.g. Pb, B, are available upon request.
The AED is a versatile instrument which can be used for a large number of applications in different industries like:
petrochemical industry (e.g. sulfur in fuel, SimDis)
environmental analysis (e.g. organotin- or organomercury compounds, pesticide screening)
military (e.g. chemical warfare agents)
high-purity gases (trace analysis)
element specific detection of more than 26 elements
low detection limits
qualification and quantification
suitable for routine analysis and research
operating up to 450 °C
multi-element detection in one GC run
