Glow discharge spectrometers

manufacturer: Horiba Scientific

Developed by HORIBA Scientific Pulsed RF GDOES (Pulsed RF GDOES) spectrometers, they are a new technique for studying new materials, coatings and treatments that reach the nano level of layer thickness. In addition to profile analysis, the devices provide accurate real-time information on the chemical composition of the test samples and layers.

Applications are unlimited due to the fact that analyzes are possible on almost all materials and surfaces, whether or not they are electrically conductive. Some typical applications can be given as an example:

– monitoring of photovoltaic layers in terms of thickness and composition.
– study the causes of corrosion in painted car parts.

Sample result display: Gold plated nickel-phosphorus base on brass.

– control in the production of hard drives, LEDs, lithium-ion batteries, etc.
– chemical analysis of impurities in the production of pure precious metals such as gold, platinum, silver, etc.
– UV protective and energy-efficient coatings applied to flat windows for buildings, car windows and… many more.

Measurement method:
In contact with the sample, argon is excited to a plasma state, which erodes the sample at a set speed. The material penetration depth is 1 nm and can pass 150 microns with a resolution of better than 1 nanometer. In some materials, the measurement is in a pulsed mode to avoid overheating. The gases released are taken out and analyzed in an optical or mass spectrometer. This determines the chemical composition assigned to a specific location of the coating or material.

This is undoubtedly the only analytical method that allows simultaneous surface, profile and precision elemental analysis (including gaseous elements) of solid samples ranging from metals and metal coatings through organic and polymeric materials, composites, glass and ceramics. etc.




Patented expert software allowing less than 2 minutes to download the full emission spectrum of a sample or high-resolution layer and non-minimal dynamic range (patented, highly dynamic detectors).

A huge library of spectral lines for all the elements is built into the software. Using IMAGE requires a monochromator.
