The Chirascan Q100 Circular Dichroism (CD) Spectrometer offers comprehensive insight into the Higher Order Structure (HOS) characteristics of complex biomolecules. High-performance CD spectrometry and reproducible robotics combine to produce quality data compatible with the most strict statistical analysis techniques. The outcome: objective, statistically-validated HOS comparisons. Fully integrated for unmanned operation, the Chirascan Q100 saves days of operator time, analyzing 48 buffer-sample pairs in 24 hours whereas a skilled operator can process only up to 14 samples per day on a manual system.
