Sample Preparation

EMiL offers comprehensive sample preparation facilities to ensure high-quality samples for electron microscopy analysis. From initial rough grinding with silicon carbide grinding papers to final fine polishing for EBSD, EMiL provides all the necessary tools for thorough sample preparation. Researchers can achieve intermediate polishing with diamond paste or aluminum oxide powder, and finalize their samples with vibration polishing using alumina or colloidal silica solutions for the highest quality finish. Additionally, EMiL offers sputter coating services, allowing samples to be coated with gold or carbon to improve conductivity and imaging quality.

Our lab is now equipped with the Pelcon Automatic Thin Section Machine, perfect for preparing thin sections of concrete, rock, sand, and aggregate samples. This machine performs all cutting, grinding, and finishing operations automatically, ensuring consistent and uniform thickness across specimens. With its precision diamond drum grinders, the Pelcon achieves micron-level flatness, making it ideal for both standard petrographic analysis and more advanced microscopic studies. This addition enhances our ability to produce high-quality thin sections without the contamination risks associated with traditional techniques. For SEM work, additional polishing with diamond paste and vibratory polishing might be required depending on the analytical objectives.

The Pace Technology GIGA-0900 is a 9-inch metallographic vibratory polisher designed for preparing difficult-to-polish materials with gentle action. It is particularly effective for electron backscatter diffraction (EBSD) sample preparation. The device operates by setting a default frequency to initiate vibration and adjusting the voltage to control the rotational speed.
