Ensure that all the parts including optical lens, telescope lens and Polarimeter tube are clean. Maintain the temperature of solution throughout operation as mentioned in standard test procedure. 5.2 OPERATION. Switch on the instrument and let the sodium lamp (λ = 589.3 nm) elute to its maximum brightness, it will take about 20 minutes. .4.5.2. Clean the sample cell or tube using appropriate cleaning procedures recommended by the manufacturer or the laboratory’s standard operating procedures. 4.5.3. Store the Polarimeter and sample cells or tubes in a clean and secure location . Ensure that all the parts including optical lens, telescope lens and Polarimeter tube are clean. Maintain the temperature of solution throughout operation as mentioned in standard test procedure. 5.2 OPERATION. Switch on the instrument and let the sodium lamp (λ = 589.3 nm) elute to its maximum brightness, it will take about 20 minutes. .
[][]Zero the polarimeter using purified water in the 1dm polarimeter tube. [][]Determine the optical rotation of each solution at 20°C ± 0.5°C in the 1dm tube. [][]Record and calculate the results obtained for each solution on the polarimeter calibration check sheet using the following calculation: A=αx100x100/I x c x(100-%LOD) Where,In a polarimeter (figure 2), plane-polarized light is introduced to a tube (typically 10 cm in length, figure 3) containing a solution with the substance to be measured. If the substance is optical inactive, the plane of the polarized light will not change in orientation and the observer will read an angle of [α]= 0 o. If the compound in the .Maintaining a Polarimeter: Clean Regularly: Clean the exterior with a soft, lint-free cloth. For optical components, use lens-cleaning tissue and solvent (like ethanol), if permitted by GAO Tek. Sample Tube Maintenance: Clean sample tubes thoroughly after each use. Ensure they are dry and free of residues. Check for Calibration:
5.1.33 Clean the polarimeter tube with distilled water if solutions are prepared in polar solution or clean the polarimeter tube with methanol or ether if the solvent is non-polar. 5.1.34 Keep the tube in the tube box. 5.1.35 Enter the details in the logbook. 5.2 Calibration.
Question: Some polarimeter tubes need cleaning before placing sample within for the polarimetry reading. However, some traces of water can be found after cleaning so the laboratory textbook suggests to "rinse the tube with the .

Rudolph Research Analytical 55 Newburgh Road Hackettstown, NJ, 07840 USA Phone: 973-584-1558 Fax: 973-584-5440 [email protected] 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 a neat sample). Usually, the sample is dissolved in a solvent and the resulting solution is placed in the tube.
polarimeter instructions
A polarimeter is the entirety of light source, polariser, polarimeter tube, analyser and detector. If a tube with no optically active substance is placed between two parallel polarisation filters, the oscillation plane is retained. Light will be visible on the screen at the end. . Maximum ease of use during filling and cleaning is guaranteed .
The scope of this standard operating procedure includes calibration of Polarimeter. 3.0 RESPONSIBILITY. 3.1 Section Incharge. 3.2 Technical Manager. 3.3 Q.A.
