The novel database design is based on the hierarchical cluster analysis of reference spectra in the spectral range from 3600 to 1250cm1. The hereby generated database entries were optimized for the automated analysis software with defined reference datasets. The design was further tested for its ...

1b), and the spectrum for each of the MPs was visualised and compared to a spectral reference database (Fig. 1c). Fig. 1 a Optical image of the raw sample created by the μFT-IR imaging system; b spectra map of the MPs identified in the raw sample; c example of a particle ...

The reference database houses thousands of spectra, so samples can be identified. The molecular identities can be determined through this process. FTIR Sampling Samples as small as 10 microns can be evaluated using FTIR analysis. The tiny sample size allows for cost effective identification of parti...
Fiveash Data Management, Inc. publishes FTIR, ATR/FTIR and Raman spectral libraries and the FDM SearchFaster(tm) software.
We eliminated any known components in the system by running the reference spectra and comparing our unknown to these reference spectra. No matches were found. At this point, the library search was the best chance. Figure 2 shows the results of the FTIRsearch, which identified our compound as ...
tricky. All spectroscopies are essentially theoretical, and sometimes the matching process may lead to uncertainties. Two very similar, but functionally unique, compounds may exhibit nearly identical spectra. The material you’re analyzing may not be a pure as the reference sample in the database. ...
Library search uses a mathematical algorithm to measure a correlation between a given material spec- trum and the available reference spectra in the library database. The library search method can detect differences in the 5 to 10 % range between samples and analo- gous reference spectra. ...
Based on the experience gained in this study, a reference control spectrum to be used in such comparisons should be constructed (by averaging) using the spectra of children of the same age and gender. Thus, it is proposed that the average spectrum constructed from a pool of 3-year-old boys...
