Atomic Absorption Spectrophotometer LAAS-A10

Atomic Absorption Spectrophotometer LAAS-A10


Atomic Absorption Spectrophotometer comprises of high performance and a wide spectral range photomultiplier tube. Incorporation of Czerny-Turner monochromator helps in selection of specific lights to allow determination of specific elements. It is equipped with gas leakage alarm which shut downs the system as a safety measure. It is highly recommended spectrophotometer to analyze smallest amount of element from mixture, also in forensics and chemistry, biological science to detect toxic elements from blood and drug samples.
