(54) СПОСОБ КОМПЕНСАЦИИ ФОНОВОЙ ФЛУОРЕСЦЕНЦИИ В МНОГОКОМПОНЕНТНОЙ СИСТЕМЕ(54) METHOD OF COMPENSATION OF BACKGROUND FLUORESCENCE IN A MULTICOMPONENT SYSTEM
1one
Изобретение относитс к области оптических способов анализа состава вещества, а более конкретно к способам выделени спектра флуоресценции анализируемого примесного компонента из суммарного спектра сложной многокомпонентной смеси типа нефти .The invention relates to the field of optical methods for analyzing the composition of a substance, and more specifically to methods for isolating the fluorescence spectrum of an impurity component under analysis from the total spectrum of a complex multicomponent mixture such as oil.
Известны способы компенсации фоновой флуоресценции в многокомпонентных смес х 1.Known methods of compensation for background fluorescence in multicomponent mixtures x 1.
Наиболее близким по технической сущности вл етс способ компенсации фоновой флуоресценции в многокомпонентной системе при исс едованни примесных флуоресцирующих соединений путем вычитани по двух .лучевой схеме спектра флуоресценции образца The closest in technical essence is a method for compensating background fluorescence in a multicomponent system in the study of impurity fluorescent compounds by subtracting the sample fluorescence spectrum using a two-beam scheme.
Недостатком его вл етс невысока чувствительность , а также невозможность выделени спектра флуоресценции анализируемого компонента из суммарного спектра многокомпонентной смеси неизвестного состава.Its disadvantage is low sensitivity, as well as the impossibility of separating the fluorescence spectrum of the analyzed component from the total spectrum of a multicomponent mixture of unknown composition.
Целью изобретени вл етс повыщение чувствительности и обеспечение возможности выделени спектра флуоресценции анализируемого компонента из суммарного спектра многокомпонентной смеси неизвестного состава.The aim of the invention is to increase the sensitivity and enable the fluorescence spectrum of the analyzed component to be isolated from the total spectrum of a multicomponent mixture of unknown composition.
Это достигаетс благодар тому, что в способе компенсации фоновой флуоресценции в многокомпонентной системе при исследовании примесных флуоресцирующих соединений путем вычитани по двухлучевой схеме спектра флуоресценции образца, флуоресценци образца .возбуждаетс излучением с длиной волны, соответствующей максимуму в спектре поглощени анализируемого примесного соединени , а в качестве эталона используетс тот же самый ббразец , црзбуждаемый излучением той же интенсивности , длина волны которого соответствует области менеее интенсивного поглощени в спектре анализируемого соединени .This is due to the fact that in the method of compensating for the background fluorescence in a multicomponent system in the study of impurity fluorescent compounds by subtracting the fluorescence spectrum of a sample using a two-beam scheme, the fluorescence of the sample is excited by radiation with a wavelength corresponding to the maximum in the absorption spectrum of the analyzed impurity compound, and as a reference the same sample is used, which is induced by radiation of the same intensity, the wavelength of which corresponds to a region less than intense absorption in the spectrum of the test compound.
