Изобретение относитс к способам определени химического состава вещества.The invention relates to methods for determining the chemical composition of a substance.
Известны способы тр мого атомдо-абсорбционного анализа, например, путем катодного распылени металлов инертным тазом в разборной Т1руб.ке € лольгм катодом или с помощью дуги 1переменного тока в качестве атомизатора .путем измерени поглощени светавого потока в межэлектродном Промежутке в периоды горени дуги. Недостатки этих способов состо т iB плохой -восггроизводимости результатов и сложности реализации.Methods are known for the solid atomic absorption analysis, for example, by cathodic sputtering of metals with an inert basin in a collapsible T1 rub. By a hollow cathode or by using an alternating current arc 1 as an atomizer. The disadvantages of these methods are iB poor-performance and results of implementation complexity.
Предложенный способ атомно-абсорбдиоНного анализа заключаетс в том, что дл диспергировани и испарени металлических образцов используетс иоировой разр д, а образовавшиес пары «месте с потоком воздуха или другого газа подаютс в плам газовой горелки.The proposed method of atomic absorption analysis consists in using an ionic discharge to disperse and evaporate metal samples, and the resulting vapor with air or other gas is fed into the flame of a gas burner.
Способ по сн етс чертежом.The method is explained in the drawing.
Светом лампы 1 просвечивают плам газовой горелки 2, в которое потоком воздуха внос тс пары анализируемого образца металла.The light of the lamp 1 illuminates the flame of the gas burner 2, into which the vapor of the analyzed metal sample is introduced by air flow.
Анализируемые образцы устанавливают в держатели 3, помещенные в проточной камере 4. Держатели подключают к искровому генератору 5.The analyzed samples are installed in the holders 3, placed in the flow chamber 4. The holders are connected to the spark generator 5.
При анализе серебр ных корольков на содержание золота предложенным способом чувствительность оцределени золота составила около 0,001%. Коэффициент вариации равен 4-15% в зависимости от .концентрации. АнаЛИЗ сплавов может быть осуществлен на типовом атомно-абсорбционном спектрофотометре с искровым генератором.When analyzing the silver beads for gold content by the proposed method, the gold determination sensitivity was about 0.001%. The coefficient of variation is 4-15% depending on the concentration. AnALYSIS of alloys can be carried out on a typical atomic absorption spectrophotometer with a spark generator.

Способ атомно-абсорбционного анализа :металлических образцов с использованием пламени в ка:чест1ве атомизатора, отличающийс тем, что, с .целью ускорени процесса испарени и диспергировани образцов, примен ют искровой разр д и образующиес пары потоком газа ввод т в плам .Atomic absorption analysis method: metal samples using a flame in a caterpillar of the atomizer, characterized in that, in order to accelerate the process of evaporation and dispersion of the samples, a spark is used and the resulting vapors are introduced into the flame by a gas stream.
