GDS950 Extended Range Glow Discharge Atomic Emission Spectrometer

Our GDS950 Glow Discharge Spectrometer (GDS) offers state-of-the-art technology designed specifically for routine elemental determination and compositional depth profiling in most electrically conductive and non-conductive solid matrices. User-friendly Cornerstone brand software is brought to the platform for increased usability, simplified reporting, and streamlined analysis times—saving you time in your lab.

Features:

The glow discharge source brings a number of advantages, including:

• Simple, linear calibrations when compared to other sources
• Controlled excitation that occurs away from the sample surface
• Reduced reference material consumption
• Automatic cleaning between analyses saves time and minimizes matrix effects for increased analytical performance

The detection system ensures stability, flexibility, and performance, with the following specifications:

• Full wavelength coverage from 120 nm to 460 nm
• 30 pm (0.030 nm) resolution to differentiate even the most complex features of bulk spectra

Optional CDP Analysis Support is available.

• Compositional depth profiling of solid electrically conductive samples
• Ideal for plating, galvanizing, cladding, and other conductive surface treatments

Cornerstone software provides simplified analysis and reporting.

Applications:

The GDS950 is ideal for bulk elemental determination in metals or other solid materials like steel, cast iron, titanium, and other metals. When equipped with the CDP option, it expands the capability to compositional depth profile analysis of surface features like galvanizing, plating, heat treatments, and cladding. Application capabilities are further expanded with the DC/RF lamp option, which expands both bulk and CDP to include solid electrically non-conductive materials like paint, glass, plastics, and more.

Models:

GDS950 glow discharge spectrometers can be fitted with a variety of options depending on the type of analysis desired, the sample type(s), and the environment in which the system is installed.  Choices include:

Glow Discharge Lamp:

• DC only for solid electrically conductive samples
• A combination DC/RF lamp for both electrically conductive and non-conductive solid samples

Analysis Software Support:

• Bulk only, for the determination of bulk elemental composition
• Bulk and CDP, for both the determination of bulk elemental composition, and compositional depth profiling

Spectrometer Extension:

• Choice to add an extension spectrometer, to expand the upper wavelength range from 450 to 850 nm

Vacuum Pump Type:

• Rotary vane pump for standard lab environments
• Dry Roots pump for oil sensitive lab environments like clean rooms
