Instrument Details

The ElectroPointer is specifically designed to assist in the process of electropolishing for preparing specimens for atom probe tomography (APT). It involves the removal of material from a metallic sample’s surface through an electrochemical process, where the sample acts as the anode in an electrochemical cell, a conductive liquid electrolyte is chosen based on the material being polished, and a cathode made of platinum, completes the circuit.

This equipment provides control over the electropolishing process, enabling the production of high-quality needle-shaped specimens.

Key Features of the ElectroPointer:

1. Electropolishing System:
   • Provides controlled DC or AC voltage to achieve uniform material removal.
   • Ensures the formation of a smooth, defect-free surface critical for APT analysis.
2. Integrated Microscope:
   • Features real-time imaging capabilities for monitoring specimen geometry during electropolishing.
   • Allows precise detection of the specimen’s apex and taper geometry.
3. Electrolytes:
   • Compatible with a wide range of electrolytes tailored for different materials.

Advantages of Using an ElectroPointer:

• Efficiency: Reduces the time and effort required for preparing APT specimens.
• Reproducibility: Ensures consistent specimen quality.
• Precision: Produces sharp, well-defined needle tips essential for atom probe tomography.
• Flexibility: Adaptable to different materials and research needs.
