SEOS-02 advantages

Alloys and elements to analyze

  • SEOS-02 identifies the composition of iron alloys (all types of steel and cast iron) and non-ferrous alloys on any basis (Al, Cu, Zn, Ni, Ti, Mg, Co, Pb, etc.).
  • CCD allows to analyze the whole range of basic elements used in metallurgy, including S, P, C.

Metrological performance

  • SEOS-02 measurement accuracy is in accordance with international regulatory documents.
  • Every SEOS-02 spectrometer passes state verification procedure as a measuring instrument.
  • These tests prove advanced metrological parameters of 5E05-02 spectrometers.
  • Measured elements concentration range: 0.0005% – 45%.
  • Relative error: 0.3% – 5% (depending on the concentration).


  • SEOS-02 spectrometer has the best price/performance ratio.

Special features

Optical block

Vacuum construction:

  • Allows to get the best metrological characteristics among the spectrometers made with CCD;
  • Does not depend on the noble gas quality in comparison with the non-vacuum analogues.

New polychromator construction:

  • Is more solid and easy to maintain;
  • Allows to adjust key spectral lines as precisely as possible;
  • Permits resetting in case of considerable changes in analytical tasks.


New composite material frame design ensures:

  • Outstanding interference immunity;
  • Temperature oscillations resistance;
  • Ambient influence protection;
  • Easy maintenance.

Spark generator

New spectrum excitation source allows to choose optimal for the existing analytical task configuration.
Various modes and their combinations – high-energy sparking, spark modes with various options, including quasi-arc - allow to deal with wide range of analytical tasks, including ultra pure copper and high silicon content alloys analysis.

Spark rack

New construction ensures:

  • Easy and quick sample setting;
  • Simple tungsten counter electrode maintenance;
  • Quick (≤ 30 s) safety glass replacement;
  • Bidirectional argon air cooling and adapters allow thin and small sample analysis.


SEOS-02 software is adapted to Microsoft Windows and has a wide range of functions:

  • Control of the gas-vacuum system;
  • Automatic profiling and accounting drift;
  • Graphic spectrum representation with the opportunity of spectral lines identification;
  • Analysis results export to MS Office;
  • Concentration estimation (% and ppm);
  • Alloys database with the opportunity to add one's own grades;
  • One-point and two-point recalibration;
  • Analysis process indicator and electronics self-diagnostic;
  • Qualitative analysis if there are no corresponding methods installed on the spectrometer;
  • Free access to the factory calibrations and curves;
  • Opportunity to create one’s own analytical methods;
  • Individual spectral background account for each line;
  • Several spectral lines and comparison lines for each element;
  • Automatic best comparison lines selection;
  • Unique processing results algorithm, based on correlation analysis for the random and systematic errors reduction;
  • Automatic inter-element additive and multiplicative effects account.

SEOS-02 analysis results:

  • 5 parallel measurements (C1, C2, СЗ, C4, C5)
  • Average chemical element concentration value (Average)
  • Relative standard deviation (SD rel, %)
