Multi-spectral Chemical Characterization System (MCCS)

Examples of User Application

All three parts of MCCS, Peak Identification, Spectral Chemical Identification, and Spectral Search, can display the results of their analysis in both graphic and table format. The Peak Identification provides fitted and measured graphs and tables of the input raw data. The SCI module provides chemically identified results of the input data from the Peak Identification in terms of graphs and tables. The Interactive Display provides the reference graphs and tables.

The raw data usually covers a wide range of physical and chemical processes from low concentration and low temperature to high pressure and high temperature environments and matrix conditions. The spectra are subjected to shift, broaden, and interfere. They are difficult, if not impossible, to establish in a one-to-one correspondence with the reference data. It is essential to develop a method so that the one-to-one correlation between the input data and the reference data can be established. All the graphs are visually comparable, can be graphed on the same scale and can be shifted relative to each other. This allows the user to correlate the data and look for regularities and systematics. This also gives the scientist an overview of what the program is doing every step of the way so that the scientist can make corresponding decisions.

The following examples show how the Interactive Display program can effectively be used to generate the best possible identification.
