Известен способ атомно-абсорбционного определени элементов. При использовании этого метода в качестве атомизатора, а котором анализируемое вещество преобразуетс в атомный пар примен етс плам газовых смесей. При этом, навеску пробы химическим спсобом перевод т в раствор, который путем пневматического распылени вводитс в плам газовой горелки. Плам просвечиваетс свето.м источника , излучающего резонансную линию анализируемого элемента. По величине относительного уменьшени интенсивности света резонансной линии в пучке, прошедшем через плам при введении в него раствора , определ етс концентраци анализируемого элмента в зоне пламени и соответственно в растворе и в пробе 1J. A known method for the atomic absorption determination of elements. When using this method as an atomizer, and which the analyte is converted to atomic vapor, flame gas mixtures are used. In this case, the sample is transferred by chemical means into a solution, which is pneumatically sprayed into the flame of a gas burner. The flame is illuminated from the lights of the source emitting the resonance line of the element being analyzed. The concentration of the analyzed element in the flame zone and, respectively, in the solution and in the sample 1J is determined from the magnitude of the relative decrease in the intensity of light of the resonance line in the beam that has passed through the flame when the solution is introduced into it.
Недостатками этого метода, преп тствующими широкрму внедрению его вThe disadvantages of this method, which prevent its widespread implementation in
вл ютс необходимость химического перевода анализируемой порошковой пробы в раствор, что -значительно снижает экспрессность и производительность ансшиза, и использование пламени, которо .е требует пр)именени горючих и окислительных газов и приводит к громоздкости аппаратуры за счет газорых баллонов и компрессоров. УкаO занные недостатки привод т к тому, что суиествукхдие атомно-абсорбционные фотометры в услови х палевых партий и отр дов примен тьс практичес- ки не могут. :are the need for chemical conversion of the powder sample being analyzed into the solution, which significantly reduces the expressiveness and productivity of the unshizze, and the use of a flame, which requires the replacement of combustible and oxidizing gases and leads to the cumbersomeness of the apparatus due to gas cylinders and compressors. These deficiencies lead to the fact that atomic absorption photometers under the conditions of pale-yellow parties and orders cannot practically be used. :

Известен способ определени элементов в пробах горных пород, заключам (1:ийс в нанесении исследуемой пробы на графитовый электрод, импульсном , нагреве до испарени пробы и измерении уменьшени относитель0 ной интенсивности резонансной линии в пучке света, проход щем над поверхностью графитового электрода 2. Однако в этом способе при нагрева 5 пробы одновременно с анализируегллм элементом испар ютс мешающие примеси и частицы основы, которые создают лохшое неселективное поглощение, преп :.ствующее проведению анализа. ПОЭТОМУ как и при использовании пла0A known method for determining elements in rock samples is the conclusion (1: in the application of the test sample to a graphite electrode, pulsed, heated before the sample evaporates, and measuring the decrease in the relative intensity of the resonance line in a light beam passing over the surface of graphite electrode 2. However In this method, when heating 5 samples simultaneously with the analyzing element, the interfering impurities and base particles evaporate, which create a crumbly non-selective absorption, prep: analyzing the analysis.
