JASCO｜Circular Dichroism Detector

The CD-4095 is a unique HPLC CD detector for measuring circular dichroism developed from the market leading J-Series circular dichroism spectropolarimeters. Optically active compounds with a chromophore close to a chiral center may absorb circularly polarized light, which can be detected with excellent sensitivity and selectivity.
Model : CD-4095

Feature :

  • The CD detector is possible to positively distinguish between the d- and l- enantiomers by measuring their positive and negative peaks.
  • It is also possible to quantify the d- and l-forms even when they are not separated; a calibration curve based on the g-factor can be used to determine the enantiomeric ratio.
  • ChromNAV CDS can be used to simultaneously measure the CD, g-factor data and UV-visible signals.
  • The CD spectra of eluted compounds can be measured by triggering scanning manually, by timed program or automatically by threshold.
