Introduction
Tungsten carbide is a synthetic compound known for its high melting point (2870ºC) and hardness (8.5-9.0), making it suitable for various applications such as tools, abrasives, and industrial drills. It is often combined with cobalt to form cemented carbide, enhancing the durability of wear parts and mining tools.

Analysis Challenges
Analyzing trace elements in tungsten carbide is complex due to the need for sample digestion, which can be time-consuming and risk contamination. The Teledyne Leeman Labs Prodigy DC Arc allows for direct analysis of solid samples, improving speed and detection limits.

Experimental Setup
The Prodigy DC Arc, featuring an 800 mm focal length Echelle optical system and a large-format detector, was used for analysis. It provides continuous wavelength coverage from 175 to 1100 nm, allowing for efficient data collection with a single DC Arc burn, reducing electrode consumption and analysis time.

Operating Parameters
Samples were mixed with a carrier blend and analyzed using specific DC Arc conditions. The instrument was calibrated with tungsten metal standards, and data collection was optimized for each element's emission profile.

Results and Discussion
Detection limits for various elements were determined, with some limits affected by impurities in the sodium fluoride carrier. The Prodigy DC Arc's design ensures reproducible sample burns and reliable detection limits.

Conclusion
The Prodigy DC Arc provides a robust method for analyzing trace elements in tungsten carbide, offering high sensitivity and reproducibility.
