Objects of analysis
- Solids: catalysts, metals, alloys, geological materials, soil and others.
- Liquids: inorganic substances solutions in water and in organic compounds.
The method is widely used for estimation of the metal admixtures content (especially toxic ones) in sewage, lubricants and petroleum products as well as biological items: plants, food products and others.
Applications
Qualitative and quantitative analysis of all chemical elements exclusive of H, O, N, C, halogens.
The range of determined concentrations from 10-6 up to 10 g/l.
Advantages
- high sensitivity;
- high reproducibility;
- simultaneous evaluation of a large number of the components.
Instrument facilities
AAS-3 Spectrometer, PST (“Baird”).
Samples requirements
Weight of the solid samples from 1 to 10 g, solution – more than 10 ml. It is desirable to present “a reference sample” containing no elements to be defined. It is possible to prepare the sample to the Customer’s order.

Objects of analysis
Various solid and liquid samples.
Applications
Qualitative and quantitative analysis of components from magnesium to uranium.
| Range of determined concentrations, % (mass) |
0,001÷100 |
| Range of detection, % (mass) |
0,001÷0,01 |
Advantages: solid sample analysis without destruction, small weight of the solid sample (milligrams)
Instrument facilities
- SPRUT-001 semiconductor X-ray energy-dispersion spectrometer.
- VRA-30 X-ray fluorescent scanning spectrometer.
Samples requirements
Solid sample in the form of powder or particles of homogeneous material with a size of up to 10 mm. Minimum weight of powder sample is 3-5 mg. Volume of liquid sample – not less than 10 ml. Along with the sample it is necessary to provide a reference sample containing no elements to be defined or initial substances used for sample preparation. The accuracy of qualitative analysis drops for the samples of unknown composition.
