Revolutionary Diamond Substrate Analysis with AirSEM

In materials science, seeing is believing—but analyzing diamond substrates after removing metal coatings has always presented a challenge. Until now.

AirSEM technology has successfully checked diamond substrate cleanliness after metal coating removal without needing another coating for analysis. This breakthrough solves a common problem where preparing samples for analysis could potentially affect results.

What makes this achievement special is AirSEM’s ability to analyze chemical composition on an uncoated diamond substrate in normal air. The technology can detect elements as light as Boron without any sample preparation.

The traditional problem was straightforward: ensuring a diamond surface is clean after removing a metal coating typically required analysis methods that themselves needed additional coating—creating a circular problem. Traditional SEMs simply wouldn’t work for this task.

By examining samples in open air with no preparation needed, AirSEM confirms with certainty that cleaning processes work and surfaces remain clean. This direct approach eliminates the sample preparation problem that has challenged researchers for years.

This advancement represents a significant step forward for materials testing, creating new possibilities for diamond analysis where surface accuracy matters most.
