CD, MI 551

(JASCO 715)

CD spectropolarimetry utilizes left- and right- circularly polarized beams of light to excite optically active samples. The difference in emission intensities released perpendicular to the excitation light is then measured for the sample, and the temperature scan data and spectrum are obtained and displayed.

Parameters and Options:

·         Spectral range: 165-900nm.

·         Temperature range: -10 to 110 Celsius

·         Spatial band width: .1, .2, .5, 1, 2, 5, 10nm, manual

·         Slit width: 1-300 µm

·         Measurement sensitivity: 1, 2, 5, 10, 20, 50, 100, 200, 500, 100mdeg/FS

·         Magnetic Adjustments

·         2D or 3D spectrum

·         Continuous or step spectrum
