Atomic Absorption Spectrophotometer XMAS-A20

The Atomic Absorption Spectrophotometer XMAS-A20 is a high-performance analytical instrument designed for accurate and reliable metal element detection across a wide wavelength range of 190 to 900 nm. With a wavelength accuracy of ±0.15 nm and an automatic 6-lamp turret with auto-alignment, the system ensures precise and stable measurements with minimal operator intervention.

An adjustable spectral bandwidth (0.1–2.0 nm) enables optimized, element-specific absorbance analysis. Built-in automatic gas path protection and acetylene leakage alarms enhance operational safety during routine and extended analyses.

Supporting flame and hydride methods along with deuterium background correction, the XMAS-A20 delivers excellent sensitivity, precision, and baseline stability. It is ideally suited for environmental monitoring, food safety testing, pharmaceutical analysis, metallurgy, and research laboratories requiring dependable elemental analysis.
