«Sharovaya molniya» spectroanalytical generator

 

Generators and stands are designed to excite the atomic spectra of samples for qualitative and quantitative atomic-emission spectral analysis of various materials. They are a universal devices that are a part of atomic emission spectral systems along with generators of arc and/or spark discharge.

The generator is designed to produce an electric arc and spark discharge in atomic-emission spectral analysis systems. It is designed specifically for use in the spectral analysis of the complex composition samples for the simultaneous impurities and alloying components detection of of a wide range of concentrations.

"Sharovaya molniya" is a reliable high-tech and versatile instrument designed on the basis of power IGBT-transistors. Embedded microcontroller provides a simple operation control and allows the analyst to set optimal modes of spectrum excitation, including a change of polarity, duration and current directly during a single exposure. Sequential spark and arc operation modes during a single exposure allows you to simultaneously obtain high convergence of the main components of the sample and low detection limits for impurities.

Operation modes:

  • arc modes: AC / DC arc, interrupted arc and the arc with a step-predetermined polarity current up to 40A;
  • spark modes: variable or stable polarity with a frequency range from 1Hz to 1000Hz.
