  • Spectra Manager II - Software Suite for data acquisition, analysis, and presentation, including several methods of secondary structure calculation 


Chiroptical spectroscopy has become one of most important techniques for the characterization of biomolecules, determination of absolute configuration, and stereochemical analysis. The new JASCO J-1500 is designed to meet the most demanding of CD applications. The performance level is unparalleled, and the layout is suited for adaptation to a variety of different sampling methods. The new Simultaneous Multi-Probe (SMP) acquisition allows parallel readouts of HT voltage on the PMT, absorbance, and CD.
