Embodiment Construction

[0033] In order to provide a thorough understanding of the invention, certain illustrative embodiments and examples will now be described. However, those of ordinary skill in the art will understand that the same or equivalent functions and sequences can be accomplished by different implementations, which are also intended to be included within the spirit and scope of the present disclosure. The compositions, apparatus, systems and / or methods described herein may be adapted and modified as appropriate for the application sought to be addressed, and those described herein may be used in other suitable applications, and such other Additions and modifications will not depart from the scope of the present invention.

[0034] In one embodiment, let S be the spectrum of a sample consisting of 1 ...K n of n components. Assuming the Beer-Lambert law is obeyed, the sample spectrum can be modeled as:

[0035] S = Σ i ...

Abstract

The present invention discloses a system and method for detecting the spectra of unknown components in the spectrum of a mixture and / or for verifying the presence of suspected components in the spectrum of a mixture. The system and method involves using the algorithm to perform a regression that includes the target and known spectra in a mixture, calculating a residual where the coefficient for the target spectrum is zero, called the extracted spectrum, and comparing the extracted spectrum and the target spectrum. The system and method may be used with chemometrics algorithms, multiple known spectra, and / or multiple target spectra.
