Chirascan
Circularly Polarised Luminescence

Study excited states of chiral molecules

With an additional photoelastic modulator, this Chirascan accessory provides insight into the excited states of chiral molecules. Available exclusively for the Chirascan V100.

An accessory to expand the capabilities of your Chirascan V100

  • Characterise metal iron environments—e.g., lanthanide complexes as chiral probes and in liquid crystal displays
  • Characterise biological polymers—e.g., chemiluminescence in some firefly species
  • Characterise simple organic molecules—e.g., polycyclic aromatics used as cancer drugs, or stereo-dynamic probes for analytics

Chirascan V100

 

Now also compatible with the Solid Sample Holder accessory for CPL measurements of samples in solid-state!
