Integrating Sphere

Measure powders and other opaque samples

With its small ratio of port area to inner surface area, this Chirascan accessory collects as much light as possible in CD measurements for powders and other opaque samples. Available for manual Chirascan systems.

An accessory to expand the capabilities of your manual Chirascan system

  • Collect CD data from highly scattering samples (high g-factor) such as powders (ground crystalline or lyophilised) and compressed discs made of sample in dispersant
  • User with a diverse range of chiral solid state samples, e.g., D- and L-amino acids, co-ordination compounds such as organometallic complexes, or supramolecular complexes
  • Work with hygroscopic samples thanks to fully sealable housing
