Sample Preparation and Processing

Proper sample preparation is a key component to obtaining reliable results from our suite of advanced instrumentation. As such, SSW’s facilities include a wide variety of sample preparation, surface modification and processing equipment as well as a number of specialized sample treatment facilities.
Capabilities Include:

• Sample sectioning using various dry and wet cutting tools
• Precision sectioning using diamond saw
• Metallographic mounting and polishing in cold epoxy or bakelite medium, conductive and non-conductive mounts
• Etching of polished cross-sections using suitable etchants
• Freeze fracture capability
• UV/Ozone surface cleaning
• Ultrasonic (wet) cleaning
• Basic wet chemistry facilities
• Basic glove box facilities
• High temperature (1250 C) heat treating capability
• Heat treating under various inert gases including hydrogen, argon and nitrogen
• Dosing with water vapour at controlled pressure during heat treatment
• Many of our surface analytical instruments are equipped with in-situ heating (up to 600 C) or cooling to liquid nitrogen temperatures
• Super-Panner gravity separation table for mineral separation
