Applied Photophysics Chirascan circular dichroism spectrometers

Chirascan circular dichroism spectrometers incorporate innovative optical design features to maximise light throughput, particularly in the far-UV wavelength region, and a sophisticated digital data acquisition system that facilitates the rapid collection of precise CD spectra.

The product’s digital CD spectra acquisition approach ensures that unmodified CD spectra are collected and any post-acquisition smoothing of the CD spectra will be non-distorting and completely reversible. This approach also simplifies the operation — the unit is as straightforward to use as a single-beam spectrophotometer.

The product is able to collect thermal denaturation CD spectra in a single experiment, enabling identification of the secondary structural changes associated with each phase transition. Rapid and efficient nitrogen purging, combined with a sealed monochromator housing, ensures that just 5 L/min of nitrogen are required for far-UV work.

The unit features five detection channels — CD, absorbance/transmission, HT, temperature and voltage — with simultaneous multichannel data acquisition ensuring that all key information is recorded with every measurement made. The detector position is easily adjustable and can be set close to the cell to optimise performance with highly scattering samples, eg, membrane proteins.

A large range of accessories is available, ensuring the researcher can be confident of an effective and futureproof spectrometer that can be adapted as research interests evolve.
