Abstract

Винахід належить до аналітичного приладобудування і може бути використаний для визначення вмісту хімічних елементів в пробах різноманітних типів методом атомно-абсорбційної спектрометрії. Задачею запропонованого винаходу є підвищення світлосили спектрометра, скорочення тривалості аналізу за рахунок автоматизації процесу вимірювання, а також усунення потенційного джерела помилок у вимірюванні в результаті некоректних дій оператора при ручному настроюванні компенсатора. Поставлена задача досягається тим, що в атомно-абсорбційний спектрометр, оснований на ефекті Зеємана, який містить оптично зв'язані джерело випромінювання з довжиною хвилі, що відповідає резонансному поглинанню визначуваного елемента, поляризатор, оптомодулятор, фазову пластину і атомізатор, розташований в постійному магнітному полі; оптично зв'язані монохроматор і приймач випромінювання; систему реєстрації і обробки сигналу, електрично зв'язану з приймачем випромінювання і синхронізовану з оптомодулятором; введений пристрій перетворення випромінювання, оптично сполучений з атомізатором і монохроматором, виконаний у вигляді оптично сполучених другого поляризатора і джгута світловодів із змінним профілем, причому вхідному торцю джгута світловодів придана форма, яка збігається з профілем перерізу пучка випромінювання, а вихідному торцю придана витягнута форма, і він суміщений з вхідною щілиною монохроматора.The invention relates to analytical instrumentation and can be used to determine the content of chemical elements in samples of various types by atomic absorption spectrometry. The object of the present invention is to increase the light-power spectrometer, reduce the duration of analysis by automating the measurement process, as well as eliminate the potential source of measurement errors due to incorrect operator actions when manually adjusting the compensator. This object is achieved by the fact that in an atomic absorption spectrometer based on the Zeeman effect, which contains an optically coupled radiation source with a wavelength corresponding to the resonant absorption of the determined element, the polarizer, the optomodulator, the phase plate and the atomizer, magnifier ; optically coupled monochromator and radiation receiver; a signal recording and processing system electrically coupled to a radiation receiver and synchronized with an optomodulator; introduced radiation conversion device, optically coupled to an atomizer and monochromator, made in the form of optically coupled second polarizer and a fiber optic harness with a variable profile, with the input end of the fiber optic harness being shaped, which coincides with the beam cross section profile, and it is aligned with the inlet of the monochromator.
