<p>A spectrographic apparatus and method comprising providing a spectrometer, digitizing a sample spectrum in a spectral range that includes at least one feature of an analyte, and comparing, via a linear least squares computation, the sample spectrum to a spectrum known to closely approximate the sample spectrum at a reference condition and to one or more derivatives of the known spectrum taken with respect to one or more parameters of the reference condition.</p> |
