Automatic Polarimeter

Brand : Rudolph Research Analytical
Model : AUTOPOL VI
Wavelength Range : 365nm, 405nm, 436nm, 546nm, 589nm, 633nm

  • To measure the angle of rotation caused by passing polarized
    light throughan optically active substance
  • Some chemical substances are optically active, and polarized
    (uni-directional) light will rotate either to the left
    (counter-clockwise) or right (clockwise) when passed through
    these substances. The amount by which the light is rotated is
    known as the angle of rotation. The angle of rotation is
    basically known as observed angle

Description

Applications
For mixtures of chiral organic molecules in pure or diluted form, polarimetry provides a rapid, reliable, quality check that eliminates conventional analysis like liquid chromatography which can take an hour to do what the polarimeter accomplishes in minutes. Chemists use polarimetry to test the effectiveness of catalysts and asymmetric synthetic processes.

a. Pharmaceutical industry
• Monitoring chemical process
• Purity control and determination of concentrations
• Characterisation of new synthetic substances

b. Chemical industry
• Purity control and determination of concentrations
• Analysis of optically-active components (qualitative and quantitative)
• Determination of changes in the configuration
• Monitoring chemical processes

c. Sugar industry
• Quality control of original and end product
• Determination of fructose and glucose
• Sugar concentrations in refined beet and cane sugar, molasses and beet pulp

d. Food industry
• Determination of concentration
• Purity control
• Quality control
Sample Requirements
• Solid or liquid that soluble in organic solvents
