Polarimetry 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 ][=—f c*l [a] = specific rotation l = optical pathlength in dm X = wavelength T = temperature a = optical rotation c = concentration in g/100ml...

Windows 7 Embedded Operating System No virus, no malware and direct Ethernet connection to LIMS or Server without a PC. Connect to almost any USB printer Measurement Modes The Autopol 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...

This model is available in one, two and six wavelength versions and has a more expensive optical system than the Autopol III. It is the system of choice for research universities, pharmaceutical and fine chemical research departments. This instrument is also excellent for studying racemics and kinetics. Temperature control may be accomplished through a circulating Water Bath or with Rudolph’s optional Patented TempTrol™ System, which electronically heats and cools the sample to a specified temperature without the use of water circulation. IQOQPQ documentation is included with the instrument....

Full cGMP/GLP Compliance Quality cGMP/GLP Printing No matter which model Autopol you choose, Rudolph uses the same high quality optics. While other manufacturers use Polaroid Plastic Dichroic Sheet Polarizers, Rudolph does not. Instead, Rudolph uses the same high quality Glan Thompson Calcite Polarizers in all its models. Measurement reports can be saved as an Excel or PDF file and edited quickly and easily. You can import logos and print your company’s customized “C of A” directly. Why are high quality polarizing prisms important? Because prisms are two of the most critical optical components...
