Apparatus Used: Polarimeter, a balance, measuring cylinder, beaker and a source of light. (Sodium lamp for half shade polarimeter and ordinary bulb or .
A Polarimeter is a device for studying a transparent sample between crossed polarizing devices. Jean-Baptiste Biot (1774-1862) developed the polarimeter at the right, which was made by Soliel/Duboscq of Paris ca. 1850. . Before the introduction of sheet polarizers, the practical solution to the problem of producing a linearly polarized beam .POLARIMETER (BIQUARTZ) OBJECT: To determine the specific rotation of cane sugar solution using Polarimeter. SPECIFIC ROTATION: Specific rotation is the rotation produced by a column in a solution of an optically active substance one centimeter long, the concentration of the substance being one gram per c.c. APPARATUS USED: With this foundational knowledge, you can now move on to the practical steps of using the device. How to Use a Polarimeter? Preparing the Polarimeter for Use. Proper preparation ensures the accuracy of polarimeter readings. This involves checking the instrument’s calibration and preparing the sample correctly. . Step 3: Insert the Sample .

The optical activity of a substance is measured by its specific rotation (or specific rotatory power).. The specific rotation of sugar solution is determined by the formula;. S = θ / LC. where ‘θ’ is the rotation produced in degree, L is the length of the tube in the decimeter (1 decimeter = 10 cm) and C is the concentration of the active substance in gm/cc in the solution.Polarimeter Tutorial. The Polarimeter Tutorial is an interactive animation that provides practice on reading a polarimeter's Vernier scale. Adjust the polarimeter dial until both halves have the same orange tint and the word "perfect" appears above the dial. Left-click to "freeze" the polarimeter dial.
Fill the polarimeter tube with the sucrose solution such that the path length increases by 0.5 dm in length for each observation. Record the angles of minimum light intensity. These will be the angles of optical rotation. Prepare a graph of angle of optical rotation vs. length. Since there will be two angles for each path length observation . This video provides you the most important questions of the experiment - to determine the specific rotation of sugar solution using polarimeter.=====.

Zeroing the instrument: • Turn on the polarimeter using the switch on the left side of the back of the instrument. You should see a red light turn on, on top of the machine. • Go to the PC next to the polarimeter and double-click on “Spectra Manager.”
We describe a high resolution laser polarimeter built from commodity optical components. The optical rotation angle is determined by measuring the phase difference between two harmonically . In measuring optical rotation, plane-polarized light travels down a long tube containing the sample. If it is a liquid, the sample may be placed in the tube as a pure liquid (its is sometimes called .
In this geometry, the average drift distance, and hence charge diffusion, is largely independent of the active depth, which will be limited only by practical concerns. In addition to the loss of focal plane imaging, the TPC polarimeter is inherently asymmetric, as the two dimensions of the image pixels are derived in fundamentally different ways.
Laurent’s Half-Shade Polarimeter is an optical instrument used to measure the optical rotation of substances, typically liquid solutions containing optically active compounds. These compounds have the ability to rotate the plane of polarization of linearly polarized light, a property that can be exploited to determine the concentration, purity, or specific rotation of the .What is the practical utility of the measurement of this specific rotation ?
