  Working Principles
Click to ViewAtomic Absorption Spectroscopy (AAS) determines the concentrations of metals in liquid samples. It is a process in which sample in form of homogenous liquid is aspirated into the flame and light source from hollow cathode lamp is used to excite the free atoms formed in the flame by absorption of electromagnetic radiation. Atomic absorption spectroscopy is a method for quantitative determination of metals present in sample.

  User Instructions
Analysis of iron, copper, zinc, manganese, sodium, potassium in soil, water, fish samples, feed etcIf materials are given in raw form then about 50gm of sample is required and in case of dried or grinded sample the sample amount requirement is about 10gm. The sample is prepared through acid digestion and glass filtration process accordingly. For analysis of water sample the required amount is 100ml for each.
