Sentence examples for sum spectrum from inspiring English sources

The energy resolution of the sum spectrum was 8.8%.

All the systems with different fullerene derivatives demonstrate a sum spectrum of small localized and mobile polarons whose contributions depend on the structure of the fullerene derivative.

This SUM spectrum was then analyzed quantitatively against standards measured under identical conditions (fluoroapatite for Ca and P; albite for Na, MgO for Mg; FeS2 for S; Al metal for Al; KCl for Cl; oxygen was calculated from the cation analyses by assumed stoichiometry) with interelement matrix corrections determined with the NIST electron-excited X-ray microanalysis DTSA II software [ 19].

c, 19F spin echo sum spectra acquired on as-synthesized Li2Mn2/3Nb1/3O2F and Li2Mn1/2Ti1/2O2F powders at 50 kHz MAS at a field B 0 = 11.7 T.

As an illustration, Figure 1 shows sum spectra (with 50 scans per spectrum and 0.8 cm−1 spectral resolution) acquired in the three configuration modes on the same 3 μm section of a model painting, made of lead white mixed with linseed oil (mass ratio 0.5 1).

The relative concentrations of all detected elements (Ca, P, C, O, Mg and Na and the trace elements: chlorine (Cl), Al and sulfur (S) were determined, using the summation (SUM) spectra as defined by the Ca-mask.

For example, the output of any of the source DETECT programs can be fed into dmextract to create a summed spectrum which can then be fit in Sherpa.

Each summed spectrum was smoothed, subtracted and centrioded prior to obtaining m/z values for peptide mass fingerprinting.

With the achieved SNR of the summed spectra at a TE of 288 ms, no other peaks than NAA, tCr, Cho and Lac were evident.

For calculation C20-ganglioside percentage (Figure 5), we used the most intense ion peak derived from GM1 and GD1, namely [GM1-H] − and [GD1+K-2H]−, and intensities of these peaks in the summed spectra from each hippocampal region (at least 1300 spectra were summed for one region) were used for the calculation.

Peaks were obtained from the summed spectra of 20 combined spectra per sample.
