The GDA 550 HR is designed to be equipped with more than 60 fixed analytical element channels, using photomultiplier tubes. This Glow Discharge Optical Emission Spectrometer is perfectly suitable for demanding applications requiring flexibility, high resolution, and analytical precision.

The optional High Resolution SPECTRUMA CCD optics extends the analytical capabilities of the GDA 550 HR into unmatched dimensions. This enables to add an almost unlimited number of analytical element channels to any given method.

All elements including the light ones (H, O, N, Cl and C) may be determined quantitatively.

Primarily designed to analyze coatings up to a depth of 200 μm, with a depth resolution of 1 nm to 5 nm on the surface, the GDA 550 HR is also capable of executing bulk elemental analysis (chemical composition of materials) providing superior linearity of calibration curves for complex matrices. The detection limits at most are 0.1 ppm.

The GDA 550 HR is suitable for the analysis of conducting samples.

The instrument can be used e.g. for the following applications:

  • to inspect surfaces after diffusion processes
  • to examine galvanic coating processes
  • to analyze hard material coatings via PVD or CVD
  • to assess hot dip galvanizing as well as other kinds of galvanizing
  • to determine the elemental concentration in layers and bulk material
