How to Choose

Why GD-OES Works: Evidence and Practical Benefits

GD-OES is supported by a large body of technical literature and industry practice showing it as a rapid, direct method for depth profiling conductive solids and coatings. Compared with alternative surface and thin film techniques, GD-OES provides faster depth profiling over larger areas, straightforward sample preparation, and multi-element detection across a wide dynamic range. For labs new to GD-OES, the technology is proven for plating thickness verification, contamination screening, and failure analysis when combined with complementary surface methods.

Depth resolution and speed: Studies and application reports demonstrate GD-OES can profile coatings and layered structures from nanometers to tens of micrometers quickly, making it suitable for routine quality control and research.

Multi-element capability: GD-OES detects a broad range of elements in a single run, which reduces the need for multiple analytical techniques for bulk and near-surface composition.

Minimal sample preparation: Direct solid sampling reduces turnaround time and risk of sample contamination compared with wet chemistry and some microbeam techniques.

Comparative performance: While techniques like SIMS and XPS can offer higher surface sensitivity, GD-OES provides a superior combination of speed, depth range, and ease of use for many industrial applications.

Calibration and traceability: Use of certified reference materials and standardized protocols yields quantitative results that support compliance, specification checks, and inter-laboratory reproducibility.
