Spectrophotometers Include 3-D Optical System

The new AA-7000 Series atomic absorption spectrophotometer from Shimadzu Scientific Instruments incorporates recently developed 3-D optics for enhanced flame and furnace analysis.

The AA-7000 series’ 3-D optical system is capable of producing maximum performance for both flame detection (Pb 0.015 ppm) and furnace detection (Pb 0.00005 ppm). This is achieved through optimal adjustment of the light beam and digital filter, and by using optical components that restrict light loss.

The optical double-beam photometric system is automatically set for flame measurements, and the high-throughput, single-beam photometric system is automatically set for furnace measurements. With a new graphite furnace design, the AA-7000 Series has achieved improved lower limits of detection for furnace analysis in all fields, as compared to Shimadzu’s previous series designs.

The AA-7000 has the smallest footprint of any flame or furnace AA spectrophotometer on the market, combining flame and furnace system mounts in the same compartment. When combined with an optional auto atomizer changer, the AA-7000F creates an integral burner and furnace that remains permanently installed in the combustion chamber. It supports flame analysis of high-concentration samples and furnace analysis of trace samples without changing the atomizer unit.
