Customized spectrum database for future use Case Sharing Extent of Reaction Analysis of Unknown Solid Particles Contamination Analysis Analysis of Unknown Liquid sample Measurement of the degree of cure for glues Identify substance of unknown solid particles with infrared spectroscopy and database ...
The results shown that Urethane present in almost all the paint samples but amines and hydroxyl group was prominent in the samples of Mahindra and Ashok Leyland respectively with some other resin components. In this study, a database has been created based on solubility and FTIR analysis....
The sample’s ability to absorb the infrared light’s energy at various wavelengths is measured to determine the material’s molecular composition and structure. Unknown materials are identified by searching the IR spectrum against a database that has a wide range of reference spectra. Materials can...
2.4. Data analysis After signal preprocessing the database was classified based on where they were measured naming them as core-transition-outer wood, and randomly distributed into the data matrix to avoid linearity. The spectral information generated was divided into two different data series, one ...
When individual spectra from the ASD+ group are pair-wise compared to their controls, it is observed that almost all the spectra from ASD+ children have lower absorbance at all points than those from their control children (data not shown). However, the deviation of each spectrum with respect...
Additionally, functional group information can be easily obtained from each peak. Attenuated Total Reflection (ATR) method can be used to measure extracted polymers from construction materials to obtain IR spectra, and match against the library database to identify the polymer materials. TGA is one ...
We have developed a special softwarepackage of programs with database for the treatment ofspectral data that utilizes wavelet analysis, principlecomponent analysis (PCA), image processing, artificialneural fuzzy logic, and data fusion. These programsprovide us with the ability to make base line...
The functional groups or the vibration types of the functional groups in different MPs dominate the spectral absorption or emission of the infrared spectrum and cause the changes in the spectral data over the spectral range. This motivates us to design a more effectiveness augmentation method for ...

In our case, the database contains only one spectrum—collected for PETN; spectra for C-4 and TNT were also included in this analysis as the experimental spectra and the distances between them and PETN spectrum were calculated. This summary presents the data trend of spectra in a simple way...
