Spectral Graphite Rod
Spectral analysis is a technique used to determine the elemental composition and concentration of materials. It begins with excitation—using various energy sources—followed by detection and analysis of the unique spectral lines emitted by different elements.
In this process, spectral graphite rods primarily serve as electrodes, generating either a direct current arc or high-frequency pulsed spark as the excitation source, particularly in Arc-OES and Spark-OES systems.
The optimized density and polished surface ensure reliable performance and extended lifespan.
