Spectrometer UV-Vis-NIR - Shimadzu UV 3101pc

Location: Optical Lab
Responsible: Diana Gaspar
Shimadzu UV-3101PC UV-VIS-NIR Spectrophotometer is a double-beam, direct ratio measuring system. This UV-3101 provides solutions in the analysis of films, powders, coatings, plastics and liquids. Shimadzu UV-3101PC contains two sets of three gratings to cover the wide wavelength range from the ultraviolet to the near-infrared. This gives a relatively constant energy and signal-to-noise.
Data is acquired through three basic modes: wavelength scanning, quantitative, and time scanning, with the software allowing control of all acquisition parameters and storage formats. Post analysis manipulation includes arithmetic manipulation and transformation of data,

Our Shimadzu UV-3101PC is equipped with an ISR-260 Integrating Sphere Attachment. This attachment is used for reflection and transmittance measurement of opaque, translucent, and turbid samples over a wide wavelength range from 240 nm to 800 nm.
