Including Autopol Model Selection Guide The brand of polarimeter used in more U.S. labs than any other.* SS RUDOLPH S RESEARCH ■ ANALYTICAL TECHNICAL BULLETIN 909

Polarimetry is a sensitive nondestructive technique for measuring the optical activity exhibited by inorganic and organic compounds. A compound is considered to be optically active if linearly polarized light is rotated when passing through it. The amount of optical rotation is determined by the molecular structure and concentration of chiral molecules in the substance. Each optically active substance has its own specific rotation as defined in Biot's law: [a] [=4 A. c»Z In each of these applications, the AUTOPOL offers up to six discrete wavelength selections to observe the effect of...

Measurement Modes The Autopol IV can read directly in one of four measurement modes: Optical Rotation, Specific Rotation, Concentration or Specific Rotation Plus. Specific Rotation Plus allows a correction to be applied to a result for loss on drying. Each measurement mode can be activated via touchscreen selection. Sample cells can be specified at any length (e.g., 50mm, 100mm, 200mm), or entered as a precise dimension (e.g., 199.98mm). Concentration is entered as a percentage. (See Figure 3) Cells up to 200mm Long Instruments of some manufacturers accept only special sample cells, with...

Just listen to our customers Heading “We have the AUTOPOL V from Rudolph Research Analytical (RRA)... I have used numerous polarimeters and this is by far the best. We have had it for 1-1/2 years and have had zero problems, the original lamp is still in the instrument. I recommend it over other instruments. RRA installed, trained and performed the IQOQ... It is one piece of equipment that you never worry about.” Alan Davis – Rockwell Medical Technologies Print Format Instrument Identifier Rudolph Research Analytical This sample was measured on an Autopol IV, serial number 10376,...

The accuracy of our entry-level model is +/- 0.02 Degrees Optical Rotation. This accuracy is fine for food and educational applications where budget is critical but state of the art quality is still important. The Autopol I is not a pharmaceutical grade polarimeter and does not come with IQOQ (Installation Quality Operation Quality) documentation. Please see Technical Bulletin 920 for more details on the Autopol I. Autopol II A general-purpose polarimeter with +/- 0.01 Degrees Optical Rotation accuracy. This accuracy is applicable for food, university education, many chemical, flavor and...
