Software

Proteus comes with complete data acquisition software. The software is capable of performing full spectral and kinetic acquisition. The data can be saved in the form of single wavelength kinetic, transient spectrum at a particular probe delay or full time-wavelength-deltaA surface. Such surface can be analyzed with Surface Xplorer Pro. Please refer to the Surface Xplorer Pro section for more details. Alternatively single spectra and kinetics can be processed with the third party software.

Footprint

The spectrometer dimensions are 48’’ x 23 ’’ (1220 x 585 mm)

Data format

Proteus saves data as a 3-Dimensional Wavelength-Time-Absorbance data matrix or as individual kinetics. Transient spectra can be easily extracted from the 3-D surface with Surface Xplorer or third party software. The data files format is ASCII CSV.
