                                      The POLARmonitor is a high resolution, sensitive polarimetric detector for online monitoring the Optical Rotation

                                      of chiral compounds. State-of-the-art microprocessor technology and "no moving parts" mechanical design have

                                      resulted in a detector yielding excellent baseline stability and high reproducibility.

                              

                                      The optical unit is separated from the controller unit, providing short warm up time and maximum protection in

                                      harsh environments.  Measuring cells, made of stainless steel or other biocompatible materials, are available for a

                                      wide span of flows rates and pressures,  enabling all applications in LC, SFC and biotechnology process.
