P-2000 Digital Polarimeters
The P-2000 is a configurable high precision digital polarimeter with many options for measurement range, sampling accessories and software applications. The P-2000 digital polarimeter can also be field upgraded as application requirements change. Optional wavelength filters and source lamps cover a wide range of analytical wavelengths from UV-Visible to NIR in addition to the traditional sodium (589nm) lamp used for regulatory compliance.
Spectra Manager™ Suite for has a simple user interface operating and measurement. Where a PC is not required, a second option is the intelligent remote module (iRM) with color LCD touch screen. Spectra Manager CFR is used where regulatory compliance to 21 CFR part 11 is required.
For full compliance a sodium lamp (Na589) is the preferred option, but measurement to compliance standards can be made with tungsten halogen (WI) lamp and high quality band pass filter. The third choice is a mercury (Hg) lamp that can be used with a number of intense emission lines for wavelength from visible to UV.
High Speed, Precision and Accuracy
For fast measurement, the P-2000 has a response speed of up to 6° per second, to a resolution of 0.0001°. The wide dynamic range from 0.001° to ±90° enables measurement over a very broad range of concentrations. The sample chamber includes temperature measurement with the actual temperature constantly updated and displayed on the control screen.
For a diverse range of sample types and measurements, the accessories and cells include many different options: a range of cylindrical and demountable stainless steel cells, a Peltier thermostatted cell holder and monochromator options. Quick-connect fittings with flow control valves are used for simple exchange of water jacketed cells for use with water circulators.
Validation and Regulatory Compliance
The automated validation program is compliant with the requirements of GLP/cGMP, USP and FDA. Validation is used for automated periodic testing of light source energy, zero repeatability, and rotational accuracy/repeatability. For guaranteed measurement accuracy, filters and sample cells with certified optical path length can be used and NIST-traceable calibration standards are also available.
