Показано, что метод главных компонент пригоден для идентификации спектральных различий между подобными образцами с незначительными композиционными различиями. Необработанные и нормированные ЛИЭС-спектры способны обеспечить эффективную идентификацию и распознавание содержащихся в образцах химических соединений с уровнем достоверности 95%. Измеренные концентрации находятся в хорошем согласии с эталонными концентрациями. Полученные результаты подтверждают перспективность ЛИЭС для быстрой классификации фосфорных удобрений in situ.</p></abstract><trans-abstract xml:lang="en"><p>A number of phosphate rocks and organo-mineral P fertilizers was analyzed comparatively by laser-induced breakdown spectroscopy (LIBS) in both single- and double-pulse modes associated with two chemometric methods, i.e., principal components analysis (PCA) and partial least squares regression (PLSR). PCA was demonstrated to be a valuable method for the identification of spectral differences between similar samples with only minor compositional differences. The raw and normalized LIBS spectra were able to provide effective identification and discrimination at a 95% confidence level and an in good agreement with the reference concentrations. Results obtained confirm the promising potential of LIBS for the rapid classification of P fertilizers in situ.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерно-искровая эмиссионная спектроскопия</kwd><kwd>фосфатные породы</kwd><kwd>органо-минеральные удобрения</kwd><kwd>метод главных компонент</kwd><kwd>частичная регрессия на основе метода наименьших квадратов</kwd><kwd>laser-induced breakdown spectroscopy</kwd><kwd>phosphate rocks</kwd><kwd>organo-mineral fertilizers</kwd><kwd>principal components analysis</kwd><kwd>partial least squares regression</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">R.
