Atomic Absorption Spectrophotometer NAAS-203
Atomic Absorption Spectrophotometer NAAS-203 is an analytical instrument that helps in the quantification of trace metal elements on their basis of spectral activity in gaseous states of the test under study. It is a microprocessor-controlled system with an RS232 interface that effectively controls fuel gas of burner and automatic positioning and optimization of each 8 hollow cathode lamp turret. It is equipped with an advanced flame as well as graphite furnace atomizer with rapid heating and analysis of a sample that retains the accuracy of the instrument. The audible sound alarm system effectively monitors flame conditions and ensures the safety of instruments as well as of the user.
