Jasco J-810, FDCD Spectrometer

1x JASCO, J-810, FDCD (Fluorescence-Detected Circular Dichroism) Spectrometer

Description
FDCD spectropolarimetry is a method of
spectrometry to measure the difference in emission intensities that arises when an
optically active sample is excited by left and right circularly polarized beams of lights.
Emission perpendicular to the excitation light can be measured.
The FDCD (Fluorescence detected circular dichroism) is particularly useful when measuring
multichromophoric systems such as proteins, because FDCD can selectively measure the CD
of a specified fluorescent chromophore.

The simplest method employs the TFA-335
Total Fluorescence option utilizing high pass cut-off filters for Emission
wavelength selection.
This low cost method allows simple yet sensitive detection of
Fluorescence changes during a titration or thermal ramp and also allows spectral
Excitation scans.

The FMO-427 utilizes a high efficiency monochromator for Emission wavelength
selection. In addition to Excitation scans,
the FMO-427 allows Emission scans to follow
changes in Emission wavelength during an experiment.
Both the TFA-335 and FMO-427 are used in conjunction
with either the PFD-425 or MPTC-490 Peltier temperature control systems.
