Specification

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.
Features and Benefits:
• Smallest footprint of any flame or furnace AA spectrophotometer on the market
• Supports flame analysis of high-concentration samples and furnace analysis of trace samples without changing the atomizer unit
• Single high-performance autosampler for both flame and furnace, saving capital cost and set-up time
• The first instruments in the world to be equipped standard with a vibration sensor that extinguishes flames automatically
• Other safety features include:
o a multimode automatic gas leak check and automatic air-N 2O switching for flame-specification instruments
o an argon gas pressure monitor
o over-current protection unit for furnace-specification instruments
The ASC-7000 autosampler can layer a solution in the furnace like competitive systems, but takes analysis a step further by truly mixing a sample with four other solutions, such as matrix modifiers, matrix matching, dilution or standard addition samples, for a higher level of automation. Optimal background correction methods are installed as standard, and a high-speed self-reversal method provides correction over a 185 nm to 900 nm range.
