For
excitation source a 75 watt xenon arc lamp is housed in a reflective
housing for highest excitation illumination, with high precision
regulated power supply for highly reliable lamp starting, ultra
low ripple, and high precision current regulation. Emission
detection is achieved with a fast response, high sensitivity
photon counting module with OLIS amplifier and electronics.
Scan rates to 200 nm per second are supported; software controls
speed of scanning and amount of signal averaging to be done
during fixed wavelength and scanning measurements.
The GlobalWorks™ software
package is the same as is provided in the (higher priced) OLIS
RSM 1000F, with facilities for 2D and 3D data presentation and
analysis, including peak finder, spectral deconvolution, difference
spectra, and the exclusive Olis Robust Global Fitting algorithms
for kinetic and equilibrium analysis. Data storage/retrieval,
including power import/export capabilities, are provided for
dealing with OLIS and non-OLIS acquired data. Accessories for
the DM 45 include Olis' Automatic Titration Accessory, Four
Position Cell Holders, Automatic Enzyme Assay Device, or Stopped-Flow.
