MRC specializes in marketing of polarimeters for laboratories and industry.In this article we will explain how polarimeters work.And the different models.
what this Polarimeters?
Polarimeters are instruments used to measure the rotation of the plane of polarized light as it passes through a sample of a compound that exhibits optical activity.Polarimetry measures the extent to which a substance interacts with plane-polarized light.Chemical compounds work more than form 1.
Operation of Polarimeters:
Polarimetry measures the rotation of polarized light as it passes through an optically active fluid.due to polarimeters use polarized light. The analyzer is rotated until the zero transmission condition is reached, as soon as the polarizer and analyzer transmission axes are at right angles to each other and no light passes through the instrument. whether an optical active substance is in a sample tube, the analyzer is rotated until the original dark condition is restored. The rotation is observed by looking through the analyzer, and is identified by a change in intensity of illumination. The new reading is marked on the scale and the difference between the two readings gives the amount in degrees by which the polarized light has been rotated by the optically active solution. Modern polarimeters determine rotation electronically or with lasers, The results are shown in seconds
Types of Polarimeters:
Semi-automatic,Fully automatic,Biquartz polarimeter,X-Ray Polarimeter.
