Procedures of measurement is a set of operations and rules that provide the results of measurements with the set error (ambiguity) characteristics.

Procedures of measurement and analytical programs

Generally procedures of measurement include:

  • name of the analyzed material(s), purpose, application;
  • nomenclature of detectable elements (compounds);
  • ranges (intervals) of detectable concentrations of the elements (compounds);
  • nomenclature of the certified reference materials (CRM) or reference materials necessary for calibration;
  • measurement accuracy;
  • safety requirements;
  • selection and sample preparation for analysis;
  • calibration;
  • execution of measurements;
  • processing of measurement results, estimation of the results, final results of measurements;
  • control of accuracy of analysis results;
  • certified reference materials (CRM) or reference standards.

For the control of a technological process, input and output inspection of goods and raw materials, for scientific research application of the techniques of analysis with the analytical programs, supplied with the instrument or developed by a user, is possible.

Analytical program is an integral multifunctional command of the software running a sequence of operations, programmed by the manufacturer (a user) of the analyzer. In the process of these operations the elemental (chemical) analysis of a sample placed in a sample chamber, documenting and archiving of the results is performed.

Analytical programs comprise:

  • excitation and detection modes of spectra (the parameters of laser, spectrograph, detection system, purification system);
  • basic list of spectral lines, providing the measurement of concentrations of the specified (set) elements and algorithms of intensity calculation;

  • the list of certified reference samples (or reference materials) used for construction of calibration graphs;

  • calibration curves (graphs);
  • methods of additional processing of the obtained results (if needed).
