IC Plus Ion Chambers
The IC Plus ionisation chambers are suitable for use in a number of diffraction and crystallography experiments, including protein crystallography.
The IC Plus is available in 4 standard electrode lengths to allow optimisation of the detector energy range and to fit the physical space constraints of complex end stations.
All our IC Plus Ion chambers feature adjustable plate spacings of 10mm, 14mm and 18mm, allowing the user an additional means of tuning the signal strength.
