GDA 650 HR / GDA 150 HR

Powerful and flexible instruments for daily quality control tasks

The GDOES spectrometers GDA 150 HR and GDA 650 HR are powerful instruments for Quality Control and Research, designed to take up 24/7 jobs and to be maintainable at the same time. The GDA 150 HR was developed primarily to study conductive samples, whereas the GDA 650 HR can also analyze electrically non-conductive samples.

GDA 150 HR

The GDA 150 HR glow discharge spectrometer is a robust, temperature-stabilized CCD spectrometer developed for elemental depth profile analysis and bulk elemental analysis in the production sector. The GDA 150 HR is optmized to meet the requirements of small and medium sized companies.

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

to inspect the 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

The GDA 150 HR is suitable for all electrically conductive matrices, as well as for light elements such as C, N and H (and optionally also O).

Due to the simple device operation and high speed of an analysis cycle it is possible to intervene quickly in the production process to correct any possible errors - a crucial advantage over conventional methods like metallographic investigations which need relatively long preparation time.

Flexibility in the selection of the element channels

GDA 650 HR

With the development of the GDA 650 HR the evolution of CCD glow discharge analyzers has reached the next level.

The GDA 650 HR uses the latest CCD technology in optics, which combines high resolution and sensitivity. By using the direct light path without transmission losses best detection limits are guaranteed. It is the ideal solution for customers who want precision and flexibility.

To avoid hydrocarbon contaminations the GDA 650 HR is equipped with a scroll pump. Using the installed Radio Frequency (RF) Glow Discharge Lamp, the GDA 650 HR is unexcelled in analyzing non-conductive materials such as ceramics, glass and paint layers, using the standard lamp set or a specially designed version for the universal sample unit (USU).

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

to analyze incoming base material
for depth profile in the production area
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
to analyze CIGS thin film solar cells
to analyze light elements, such as O, C, N and H
to analyze non-flat surfaces, such as pipes or spheres by using the USU

Due to the simple device operation and high speed of an analysis cycle it is possible to intervene quickly in the production process to correct any possible errors - a decisive advantage over conventional methods like metallographic investigations which need relatively long preparation time.
