• High-resolution, X-ray compositional mapping using the JEOL software package
• High-resolution electron-imaging in secondary, back-scattered and topographic mode; low-resolution cathodoluminescence imaging
• Training on both the JEOL and Probe for EPMA (PfE)™ software packages
• Remote data analysis via Probe for EPMA (PfE)™ software, downloaded directly from the ProbeSoftware Inc. website
• Thin section preparation coordinated through Dalhousie’s Thin Section Lab
• Carbon-coating of samples to be imaged or analysed using the microprobe
• In Development* – Remote usage of the JXA-8200 with online, live-time technical training and support    
• In Development* – Remote teaching – the ability of educators to use the microprobe for teaching purposes, especially important to schools that don’t have an on-site microprobe of their own
• In Development* – Remote, live-time, conferenced demonstrations for corporate and other business clients – e.g., the ability of corporate clients to show investment potential to stakeholders
