  Working Principles
Click to ViewThe “ground state” atom absorbs light energy of a specific wavelength as it enters the “excited state”. As the number of atoms in the light path increases, the amount of light absorbed also increases. By measuring the amount of light absorbed, a quantitative determination of the amount of analyte can be made. The use of special light sources and careful selection of wavelengths allow the specific determination of individual elements. In the double beam instrument the light beam from the source is split into sample beam and reference beam by the mechanical chopper. The reference beam monitors the lamp energy whereas the sample beam reflects sample absorption. The observed absorbance measurement is the ratio of the sample and reference beams which are recombined before moving to the monochromator. This arrangement compensates the effects due to drift in lamp intensity, electronic and mechanical fluctuations which affect both the sample and reference beams equally.

  User Instructions
1) Estimation of Available Ca, Mg, Na, K, Cu, Fe, Mn, Zn in soil samples. 2) Estimation of Ca, Mg, Na, K, Cu, Fe, Mn, Zn in water samples. 1) A minimum of 40 gm of soil sample is required for the above analysis. 2) A minimum of 40 ml of water sample is required for the above analysis.
