Mixture Analysis
The FDM Mixture Libraries are rapid screening tools for solving bulk mixture identification problems. Use them with your conventional libraries.
​
Searching conventional spectral libraries works well when your samples are more or less neat compounds. But search results typically degrade when additional components reach 10% relative concentration.
​
Searching mixture libraries is far easier and overall superior to spectral subtraction since no unnatural discontinuities (jagged features, distorted baselines, etc.) are inserted into your data.
​
We have two types of mixture libraries: Kits and Mixtures.
​
Kits contain defined sets of mixtures based on human knowledge and experience. For example, the FDM ATR Drug Kit has 200 sets of mixtures (like cocaine + heroin) totaling about 4250 ATR/FTIR spectra. Searching takes just a few seconds.
​
Mixtures address the problem with combinations of neat compound spectra. These libraries are much larger than the Kit libraries.
