Spectrum Instruments improve the optical precision, linear range and background correction effectively. SP-AA 4000 is an external computer controlled AAS equipped with 8-lamp positions,extinguish button, autozero button, star button, automatic gas control and atutomatic burner setting.
SP-AA 4000 is Atomic Absorption Spectrometers with state of the art performance.The instrument is equipped with two background correction techniques. Deuterium Source background correction and Smith-Hieftje Background correction are providing advantages and limitations. Combined in one instrument even complex background can be handled accurately.
