Atomic Absorption Spectrophotometer FM-AAS-A101
Atomic Absorption Spectrophotometer FM-AAS-A101 is a microprocessor controlled analyzer based on analysis of metal ions by flame and graphite furnace atomizer with absorption at 190 to 900 nm wavelength. Czerny-Turner monochromator 1800 line/mm grating optics and variance of bandwidth provides user flexibility. Provided with deuterium hollow cathode lamp, excludes interference of molecular absorption and Titanium Burner increases analysis, efficiency and precision of flame. Its double beam radiation sources enable good basic line stability. Graphic analysis system provides data on analysis of entire process i.e. measured value, temperature, procedures, time, etc.
