Application areas of laser elemental analyzer LEA-S500

Laser elemental analyzer LEA-S500 is applied for qualitative, semi-quantitative and quantitative elemental (chemical) analysis of raw material, components, additives, admixtures, inclusions at all stages of manufacturing process; for control of finished products at factories; for scientific investigations in the laboratories and institutes.

LEA-S500 detects elements from H to U, in the range from 0.01 ррм to 100%.

Furthermore, the instrument allows to perform both general averaged multi-element analysis of a sample and local analysis of small volume and mass.

The instrument is of great importance for the organizations where much care is taken about their personnel health and protection.

LEA-S500 provides safe chemical analysis of the materials and components. An operator is completely protected from harmful factors connected with the analysis.

Only several hours are needed for the instrument operation training.

Certified reference materials intended for calibration of the instrument

Certified reference materials (CRM) are samples of materials and components with certified elemental (chemical) composition intended for calibration of the instrument.

Name, field of application, certified concentrations of elements and errors of measurement are given in the certificate for any kit of certified reference materials.

The reference samples included in the State Register of approved measuring instruments have the status of the State Certified reference materials. The state certified reference materials can be used for the certification, verification and calibration purposes.

Requirements for certified reference materials (CRM):

  • Chemical composition of any CRM kit should correspond to the composition of the analyzed samples.
  • Concentrations of elements in the CRM kit should cover the complete range of possible values of element composition in the analyzed samples.
  • Also the CRM should provide reproducibility of the detected analytical signal.
  • The CRM kit and the analyzed samples should have the same structural (granulometric) composition and similar physical and chemical properties.
  • The CRM should keep the stability of metrological characteristics during the whole serviceable lifetime.
  • Optimally 3–7 pcs of CRM samples with uniform concentration laying is required for the instrument calibration.

In many sectors of national economy samples and materials that meet the requirements to CRM, are widely used.
