Applications of Mixture Analysis to FT-IR Spectra of Multi-Component Polymeric Systems

 

Introduction

IR spectral identification of multi-component samples is a challenging process:

•  Highly overlapping peaks•  Lack of specific component knowledge

•  Assignment of functional groups to a specific component

•  Time intensive one-component-at-a-time spectrum analysis

 

KnowItAll ® mixture analysis effectively addresses IR spectral identification of multi-component samples.

Mixture analysis is a mathematical process to extract:

•  Combinations of IR spectra in a library database

•  Simultaneously minimizing the residual relative to the unknown IR spectrum

 

Mixture analysis results:

•  Provide a series of potential unknown component IR spectra for evaluation

•  Improve data mining efficiency

•  Simplify search results evaluation

 

Conclusions

IR spectral identification of multi-component samples lends itself to a combination approach using mixture analysis and simple spectral search.

High degree of module interconnectivity.

Integrated with all other functionalities of KnowItAll ® .

•  Individual module provide partial answers

•  In totality a systematic and efficient analysis

Applicable to a wide variety of spectral identification problems.
