High-performance circular dichroism spectropolarimeter designed for routine CD, LD, and absorbance measurements
J-1100 is ideally suited for:
- Investigation of protein or peptide secondary and tertiary structure, including folding and conformational stability studies
- Analysis of biomolecular interactions (DNA/RNA and protein–ligand systems)
- Quality control and routine analysis, including optically active and pharmaceutical compounds
- Research in organic chemistry and stereochemistry for the characterization of chiral molecules
KEY TECHNICAL FEATURES:
- Circular Dichroism (CD) spectroscopy, with multi-signal acquisition capability (CD, LD, absorbance, etc.).
- Spectral range: 180–600 nm, covering the UV and part of the visible region.
- Light source: 150 W air-cooled xenon lamp, with an internal mercury lamp for calibration and validation.
- Monochromator: Double-prism polarizing monochromator, ensuring low stray light and high optical efficiency.
- Detector: High-sensitivity photomultiplier tube (PMT).
- Resolution and stability: Spectral resolution down to 0.025 nm, low baseline drift, high reproducibility, and low noise.
- Control software: Spectra Manager for data acquisition, spectral analysis, and accessory management.
- Thermostatted cuvette holder and Peltier temperature control systems
