媒体中に均一に分布された化合物の存在を測定スペクトルと参照スペクトルの相互相関により測定する方法

Japanese Patent JP2008507685

A

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 $\begin{array}{cc}K\left(\mathrm{delta}\mathrm{lambda},c^{\text{'}},c\right)=1/N.{\int }_{-\infty }^{+\infty }{I}^{\text{'}}\left(\mathrm{lambda},c^{\text{'}}\right).I\left(\mathrm{lambda}+\mathrm{delta}\mathrm{lambda},c\right)d\mathrm{lambda}& \left(I\right)\end{array}$ 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).
