JASCO|Circular Dichroism spectrometer║J-1100
The J-1100 uses simple optimized parameters so that a wide range of users with different levels of CD knowledge can get right down to work and successfully obtain high quality data. The wavelength range from 180 to 600 nm is suitable for obtaining secondary and tertiary structure measurements in the near- and far- UV. The intuitive Spectra Manager™ Suite of spectroscopy software provides the user with sample measurement, independent from the data processing and analysis. This allows users to obtain new measurements while simultaneously analyzing previously acquired data for increased productivity.
Feature :
- High optical throughput
- Double prism monochromator providing low stray light
- Wide dynamic range PMT detector
- Highly efficient nitrogen purge system
- Digital signal processing
- Simultaneous Multi-Probe: CD, LD, HT, DC, absorbance, fluorescence
