Chirascan Plus CD Spectrometer

Chirascan Plus CD Spectrometer

Circular dichroism (CD) is the difference in the absorbance of left-handed circularly polarised light (L-CPL) and right-handed circularly polarised light (R-CPL) and occurs when a molecule contains one or more chiral chromophores (light-absorbing groups). A primary use is in analysing the secondary structure or conformation of macromolecules, particularly proteins, and because secondary structure is sensitive to its environment, e.g.

PerkinElmer UV-Visible Spectrometer

PerkinElmer UV-Visible Spectrometer

The Lambda is a double-beam UV-Visible spectrometer that measures light absorption from the visible to the ultraviolet region (1100 nm to 200 nm, 1.1 eV to 6.2 eV). A sample is usually made up to a known concentration in a non-absorbing solvent (such as water) and loaded into a quartz cuvette (available from the lab). Liquids, solutions and transparent solids can be measured. Note that we are not able to measure reflectance on this instrument.

Renishaw inVia 2 Raman Microscope (532, 633, 785 nm)

Renishaw inVia 2 Raman Microscope (532, 633, 785 nm)

The inVia 2 is a Raman spectrometer coupled to a microscope. The microscope focuses a laser source onto specific areas of a sample then collects the light scattered off the surface of the sample and directs it through a Raman spectrometer.

Capabilities of the inVia 2 Raman Microscope:
