Atomic Absorption Spectrophotometer NAAS-100, Wavelength Range 190nm - 900nm, LABNICS EQUIPMENT Limited Company (CAT#: STEM-SE-3001-LGZ)

The Atomic Absorption Spectrophotometer NAAS-100 is an analytical instrument that facilitates the study of the quantification of trace metal elements based on the spectral activity in the gaseous state. The microprocessor control system with RS232 interface is used to effectively control the burner gas, and automatically position and optimize the 8 hollow cathode lamp turrets. It is equipped with an advanced graphite furnace to rapidly heat and analyze samples, maintaining the accuracy of the instrument. The audible sound alarm system effectively monitors flame conditions to ensure the safety of the instrument and the user.
