Показана, что трудность в измерении потока рр-нейтрино и его спектра с помощью детектора на основе жидкого органического сцинтиллятора во многом зависит от содержания изотопа 14С. Изучены оптические свойства жидкого органического сцинтиллятора, проведен хроматографический анализ.</p></abstract><trans-abstract xml:lang="en"><p>In the work, measurements of samples of the liquid scintillator sintin for the content of the isotope 14C were carried out. The difficulty in measuring the pp neutrino flux and its spectrum using a detector based on a liquid organic scintillator is shown to depend largely on the content of the 14C isotope. The optical properties of a liquid organic scintillator have been studied, and chromatographic analysis has been performed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>жидкий органический сцинтиллятор</kwd><kwd>синтин</kwd><kwd>изотоп 14С</kwd><kwd>низкофоновые измерения</kwd><kwd>синтез Фишера-Тропша</kwd><kwd>хроматографический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liquid organic scintillator</kwd><kwd>syntin</kwd><kwd>isotope 14C</kwd><kwd>low-background measurements</kwd><kwd>Fischer Tropsch synthesis</kwd><kwd>chromatographic analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cowan C.L., Reines F., Harrison F.B., Kruse H.W., McGuire A.D.
