CD (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
JASCO 1500 CD
The Jasco J-1500 CD spectrophotometer is an upgraded CD spectrophotometer with added capabilities that allow for a wide flexibility in measurement techniques. Up to four simultaneous modes can be measured, and the system's accessories allow for a wide variety of samples (from liquids, to films, to solid states) to be measured.
The accessories for the system can allow the instrument also undergo automated high-throughput experiments, temperature based absorbance experiments, and stop flow based experiments. Moreover, the wavelength of the CD has ben expanded to a range of 163 – 950nm and an optional InGaAs detector allows for the detection of up to 1600 nm.
