Shimadzu Scientific Instruments, Inc. Atomic Absorption Spectrophotometer AA-7000

The AA-7000 series' 3-D optical system is capable of producing maximum performance for both flame (Pb 0.015 ppm) and furnace detection (Pb 0.05 ppb). This is achieved through optimal adjustment of the light beam and digital filter, and by using optical components that restrict light loss. And, with a new graphite furnace design, the AA-7000 delivers unprecedented sensitivity and world-class lower limits of detection. Features Automatic switching from flame/furnace Single autosampler for flame & furnace Automatic dilution of over range samples for flame or furnace Multiple point calibration from a single standard D2 & SR background correction over entire region Comprehensive safety features, including an earthquake sensor
