Overview

Atomic Absorption Spectrophotometer LMAAS-A103 is equipped with a double-beam optical system, that operates across a broad wavelength range of 185 to 900 nm. It features flame and graphite furnace atomizers for analyzing varying concentrations of elements. It offers a maximum temperature of up to 3000°C, with ultra-sensitive detection limits of ≤ 0.8 pg for Cd and ≤ 5 pg for Cu. Integrated with a fully automatic eight-lamp position system for a wide range of elements and offers high throughput efficiency.

Features :

Automatically switchable test modes

Incorporated with titanium burner

Multiple alarm functions

Acetylene leakage monitoring

Automatic wavelength scanning and peak search

Users need to furnish their own argon gas, gas tanks, and pressure-reducing valves.
