Chiralyser for detection of optical active molecules in analytical and preparative applications

This instrument is an excellent supplemental detector to standard UV detection. For chiral separations, it permits the identification of enantiomer elution order, which is important when seeking to establish minimum levels of detection. It allows identification of enantiomeric pairs when dealing with multiple chiral centres. During the method development process, this detector enables marginal selectivity when UV detection fails.

Features

• High performance optical rotation detector
• Principle: Faraday compensation
• Identifies the chirality of a molecule with a positive or negative sign of rotation
• Detects only optically active compounds
• Can detect optically active compounds which possess little or no UV absorbance
• Works with gradients
• Simple determination of enantiomeric excess and optical purity
• Multi path flow cell (the flow cell is crossed several times by the light beam resulting in an extended optical path and increased sensitivity)
• Flow cell:
• Analytical: 100 mm / 20 µL
• Preparative: 100 mm / 300 µL
• Flow rate:
• Analytical: max. 3 mL/min
• Preparative: max. 100 mL/min
• Light source: LED 426 nm
• Detection limit: 0.5 mg/L [α =90°]
• Time constant: 0.2-5 s
• Measuring range: 32-2048 x 10-4 degree
• Resolution: 16 bit
• Noise: 20 x 10-6 degree
• Drift: 10 x 10-6 degree
• Operation via touch screen or remote control via RS 232
