Answer Posted / kirit h kaila
A polarimeter [1] is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance.[2]
Some chemical substances are optically active, and polarized (unidirectional) light will rotate either to the left (counter-clockwise) or right (clockwise) when passed through these suIsolating and identifying unknowns crystallized from various solvents or separated by high performance liquid chromatography (HPLC).
Evaluating and characterizing optically active compounds by measuring their specific rotation and comparing this value with the theoretical values found in literature.
Investigating kinetic reactions by measuring optical rotation as a function of time.
Monitoring changes in concentration of an optically active component in a reaction mixture, as in enzymatic cleavage.
Analyzing molecular structure by plotting optical rotatory dispersion curves over a wide range of wavelengths.
Distinguishing between optical isomers.bstances. The amount by which the light is rotated is known as the angle of rotation.

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
