Atomic Absorption Spectrophotometer FM-AAS-A100
Atomic Absorption Spectrophotometer FM-AAS-A100 is a fast and accurate microprocessor controlled analyzer with built-in computer data processing and LCD display. Analysis of metal ions by air-acetylene flame and graphite furnace atomizer with absorption at 190 to 900 nm wavelength. Features Czerny-Turner monochromator 1200 line/mm grating optics, paired with D2 background correction avails greater performance. Multiple atomizer configurations allow high-intensity analysis and ultimate ease of use within multiple applications settings such as environmental, agricultural and clinical, as well as high throughput labs.
