JASCO J-1000 … Opens the Door to the Future of Circular Dichroism
Chiroptical spectroscopy has become one of most important techniques for the characterization of biomolecules, determination of absolute configuration and stereochemical analysis. Since launching the Model AP-1, our first spectropolarimeter in 1961, JASCO has designed and built the finest in chiroptical instrumentation. Based on JASCO's experience in CD instrumentation over a half century, JASCO proudly introduces the J-1000 Series Circular Dichroism (CD) Spectrometers providing both unparalleled optical performance and versatile flexibility.
The latest Quad Lock-in Amplifier allows the simultaneous acquisition of up to four data channels including CD, Absorbance, Linear Dichroism (LD), Fluorescence, Fluorescence detected CD (FDCD), Fluorescence detected LD (FDLD), Fluorescence Anisotropy and Optional Rotatory Dispersion (ORD). The following figure shows the multi-probe measurement of Lysozyme showing the simultaneous acquisition of CD, Abs, Ex Fluorescence and Em Fluorescence during a thermal ramping experiment.
Designed as a “Chiroptical Spectroscopy Workbench” the J-1500 offers a wide range of accessories to allow it to be adapted to any application requirements. Temperature ramping, protein folding, enzyme kinetics, DNA/RNA interactions, natural organic chemistry, biochemistry, macromolecules and rapid scanning experiments are all possible.
The J-1100 offers the basic cell holders for general CD/LD/Abs and Temperature control measurements.
