Atomic Absorption Spectrophotometer LAAS-A20

Atomic Absorption Spectrophotometer LAAS-A20


Atomic absorption spectrophotometer designed with the latest technology, can automatically accomplish safety ignition and reproducibility of the flame method. The graphic analysis system gives information on analysis of the whole process e.g. measured value, temperature, procedures, time, etc. It consist of hollow cathode lamp to improve the analysis efficiency and accuracy of the flame & deuterium lamp for background correction.
