Overview

Atomic Absorption Spectrophotometer LMAAS-A100 adopts built in data processing system. Analyzes the concentration of elements in liquid sample based on energy absorbed from 190 to 900 nm wavelength range. LCD display indicates functions of integral holding, peak height and auto zero adjusting, deuterium lamp background correction. It is equipped with interface for externally linking PC. Double beam system can automatically compensate the light source drift and wavelength drift caused by the variation temperature and electronic circuit drift. Use of highly integrated computerized digital circuits.

Features :

Cathode lamp needs not to be pre-heated for long time and sample can be analyzed immediately
Long life and anti-corrosive atomization system
Burner is made up of new type titanium alloys, anti-corrosive and fast thermal equilibrium
Multi-functional analysis mode
Safe and reliable gas path system and high energy optical path
Optional Data acquisition software
