METHOD FOR DETERMINING THE IDENTITY OR NON-IDENTITY OF AT LEAST ONE CHEMICAL COMPOUND HOMOGENEOUSLY DISTRIBUTED IN A MEDIUM

摘要

The present invention relates to a method for determining the identity or non-identity of at least one chemical compound V' homogeneous y distributed in a medium, by a) exposing the medium containing at least one homogeneously distributed chemical compound V' to analysis radiation with a variable wavelength lambda, and b) determining the spectral measurement function I'(lambda) with the aid of the absorbed, reflected, emitted and/or scattered radiation, wherein a correlation function K(deltalambda,c',c) is determined according to Equation I maths id="MATH-US-00001" num="1" MATH OVERFLOW="SCROLL" MTABLE MTR MTD MROW MROW MIK/MI MO⁡/MO MROW MO(/MO MROW MROW MIdelta/MI MO⁢/MO MSTYLE MTEXT /MTEXT /MSTYLE MO⁢/MO MIlambda/MI /MROW MO,/MO MSUP MIc/MI MI'/MI /MSUP MO,/MO MIc/MI /MROW MO)/MO /MROW /MROW MO=/MO MROW MROW MN1/MN MO//MO MIN/MI /MROW MO./MO MROW MSUBSUP MO∫/MO MROW MO-/MO MI∞/MI /MROW MROW MO+/MO MI∞/MI /MROW /MSUBSUP MO⁢/MO MROW MROW MROW MSUP MII/MI MI'/MI /MSUP MO⁡/MO MROW MO(/MO MROW MIlambda/MI MO,/MO MSUP MIc/MI MI'/MI /MSUP /MROW MO)/MO /MROW /MROW MO./MO MROW MII/MI MO⁡/MO MROW MO(/MO MROW MROW MIlambda/MI MO+/MO MROW MIdelta/MI MO⁢/MO MSTYLE MTEXT /MTEXT /MSTYLE MO⁢/MO MIlambda/MI /MROW /MROW MO,/MO MIc/MI /MROW MO)/MO /MROW /MROW /MROW MO⁢/MO MSTYLE MTEXT /MTEXT /MSTYLE MO⁢/MO MROW MOⅆ/MO MIlambda/MI /MROW /MROW /MROW /MROW /MROW /MTD MTD MROW MO(/MO MII/MI MO)/MO /MROW /MTD /MTR /MTABLE /MATH /MATHS in which K(deltalambda,c',c) denotes the correlation depending on the relative shift deltalambda of the functions I'(lambda,c') and I(lambda,c) and the concentrations c' and c of the at least one chemical compound V' and V, c' denotes the concentration of the at least one chemical compound V' homogeneously distributed in the medium, with a known or suspected identity, c denotes the concentration of the at least one chemical compound V homogeneously distributed in the medium, with a known identity, I'(lambda,c') denotes the measurement function of the at least one homogeneously distributed chemical compound V' in a medium containing the concentration c', I(lambda,c) denotes the comparison function of the at least one homogeneously distributed chemical compound V in a medium containing the concentration c, and N denotes a normalization factor and identity or non-identity between the compounds V and V' is determined with the aid of the correlation function K(deltalambda,c',c).
