CD-2095 Circular Dichroism Detector

The new CD-2095 has been developed as an innovative CD (Circular Dichroism) detector, using the same technology applied in conventional CD spectropolarimeters, but optimized to meet HPLC requirements.

The CD-2095 detector can simultaneously determine both CD and UV absorption of the sample in the same cell for direct determination of optical purity.

CD is based on the differential absorption of right and left circularly polarized light due to the existence of a chiral chromaphore and is a much more specific technique than OR (Optical Rotation) or Polarimetry.

In the past, large and expensive CD spectropolarimeters have often been modified for use as a CD detector in an HPLC system.

The CD-2095 can easily be interfaced with the JASCO HPLC system using ChromPass Software.

Chiral separation has become one of the most important application areas in HPLC. The increasing demand for chiral chromatography in various fields, such as drug analysis, drug discovery, biochemical analysis, natural product analysis, organic synthesis, etc. have resulted in a parallel demand for better chiral separation and detection technology. Recent advances in chiral column technology are boosting the use of chiral chromatography in more and more laboratories, however, advances in chiral detection technology have only recently met the demands required in terms of sensitivity and selectivity.
