Chirascan Circular Dichroism Spectrometers

Chirascan Circular Dichroism Spectrometers

circular dichroism chirascan plus, CD, chrystalography

Chirascan sets new standards for steady-state circular dichroism spectroscopy.  It incorporates 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 more accurate and precise CD spectra.  Chirascan’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 – Chirascan is as straightforward to use as a single-beam spectrophotometer.
Other key features include:

  • Able to collect thermal denaturation CD spectra in a single experiment; enabling identification of the secondary structural changes associated with each phase transition
  • 5 detection channels: CD, Absorbance/Transmission, HT, Temperature and Voltage. Simultaneous multi-channel data acquisition ensures that all key information is recorded with every measurement you make
  •  Very low nitrogen usage. Rapid and efficient nitrogen purging combined with a sealed monochromator housing ensures that just 5 l/min is required for far-UV work
  • Moveable detector. The detector position is easily adjustable and can be set close to the cell to optimised performance with highly scattering samples e.g. membrane proteins

A large range of accessories are available, ensuring the researcher can be confident of a highly effective and future-proof spectrometer that can be adapted as research interests evolve.  These are best explored with the comprehensive brochure available on request.
Chirascan™-plus ACD is the world’s first and only truly automated CD spectrometer. Unattended operation increases the productivity of CD measurements markedly, with up to 200 samples per day now routinely achievable.  The improved productivity transforms the number and type of experiment that can be undertaken and addresses key needs in formulation and bio-comparability applications.
‘qCD’ (quantitative CD) reflects a number novel capabilities that improve performance and enable absolute CD measurements (a first in CD spectrometry).
