Abstract
A method of detecting a compound in a material sample is presented. A transformation is generated from a set of IR spectra of a set of identified compounds, in which the compound is one of the set of identified compounds. The transformation is applied to an IR spectrum of the material sample to form a transformed IR spectrum. A decomposition is applied to the transformation. Results indicative of a presence or an absence of the compound are generated based on an output of the decomposition.
Claims20
A method comprising:
- monitoring for a set of identified compounds in a material sample by:
- receiving a set of identified frequencies at an IR spectrometer, wherein the set of identified frequencies is selected for the set of identified compounds;
- loading the material sample into the IR spectrometer;
- generating a reduced IR spectrum for the material sample using the IR spectrometer, wherein:
- the reduced IR spectrum comprises a decomposition of a transformed IR spectrum;
- and
- the reduced IR spectrum has only the set of identified frequencies;
- and
- generating results indicative of a presence or an absence of a compound based on an output of the decomposition.
