Application of anti-coincidence techniques using double-layer detection offers the possibility to reject detected events with uncertain initial energy and so significantly improve the overall measured spectrum
In the second, analyte adsorbed to a 'surface plasmon stack' changes the final measured spectrum
Therefore the artifacts exposed by the splicing method have to be considered as part of the overall budget associated with the uncertainties of the measured spectrum
using a CCD array spectrometer.
Figure 2 also compares the relative difference (in percent) between the measured spectrum
, used here as the reference, and the predictions of each model (SMARTS, SPCTRAL2, and SUNSPEC) after proper smoothing to match the instrument's bandwidth (5 nm).
In fact, the measured spectrum
of sunlight that makes it to our eyes after scattering off nitrogen and oxygen molecules remains roughly as intense at violet wavelengths as it does at blue ones, he notes.
Figure 2 shows a measured spectrum
of one of the polyethylene grades.
Geometric structures in a device wafer cause distinct features in the measured spectrum
, distinguishing the sample from one having uniform film structure.
The true distribution was obtained in this case by deconvolution of the measured spectrum
24), spectral decomposition based on least square fitting techniques of the measured spectrum
to analytical descriptions of x-ray peaks is more frequently used in EDS and WDS quantitative x-ray analysis.
The measured spectrum
data is stored in a format that is compatible with most Agilent(TM) spectrum analyzers, allowing users to employ a wide range of commercially available analysis tools.
At Si, the P/B is approximately twice as high, and therefore the measured spectrum
consists of a larger contribution from the particle relative to the substrate compared to the equivalent case with a bulk carbon substrate.
It is customary to fit analytical functions to overlapping peaks in a measured spectrum
to determine peak positions, which identify the chemical state, and peak intensities, which quantify the surface composition.
