Atomic Absorption Spectrophotometer LAAS-A13

Atomic Absorption Spectrophotometer LAAS-A13

Flame Atomic Absorption Spectrophotometer LAAS-A13 is a microprocessor controlled instrument based on analysis of metal ions by flame and graphite furnace atomizer with their absorption at wavelength of 190 to 900 nm. Czerny-Turner monochromator and variance of bandwidth provides user flexibility. It is provided with deuterium hollow cathode lamp to exclude interference of molecular absorption and Titanium Burner to increase the analysis efficiency and precision of flame. Its double beam radiation sources enables good basic line stability. Graphic analysis system provides data on analysis of entire process e.g. measured value, temperature, procedures, time, etc. It has great applications in research, medicine, environmental science and other industries.
