Shimadzu Scientific Instruments has introduced the AA-7000 Series atomic absorption spectrophotometer, which incorporates 3-D optics for enhanced flame and furnace analysis.
The AA-7000 series' 3-D optical system can produce maximum performance for flame detection (Pb 0.015ppm) and furnace detection (Pb 0.00005ppm).
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.
The new graphite furnace design of the AA-7000 Series has lowered detection limits for furnace analysis in all fields, as compared with Shimadzu's previous series designs.
The AA-7000 combines flame and furnace system mounts in the same compartment, making it what Shimadzu claims is the smallest footprint of any flame or furnace AA spectrophotometer on the market.
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 atomiser unit.
The AA-7000 series gives users a single high-performance autosampler for flame and furnace, saving capital cost and set-up time.
The ASC-7000 autosampler can mix 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 to 900nm range.
The AA-7000 series is equipped with a vibration sensor that automatically extinguishes flames.
Other safety features include a multimode automatic gas-leak check, automatic air-N2O switching for flame-specification instruments and an argon gas-pressure monitor and over-current protection unit for furnace-specification instruments.
