McMaster University and the Canadian Centre for Electron Microscopy are seeking one laboratory µXRF mapping system for advanced elemental analysis.
- Buyer: McMaster University, in collaboration with the Canadian Centre for Electron Microscopy (CCEM).
- OEM: **Sigray, Inc.** is identified as the manufacturer of the requested system.
- Product: One laboratory micro X-ray fluorescence (µXRF) microanalytical mapping system for non-destructive, large-area elemental mapping.
  - Required features include a high-brightness microfocus source with selectable excitation energies and focusing optics with a spot size of 8 µm or less, independent of energy.
  - The system must support high-vacuum analysis for light elements, depth-selective capability, and sub-ppm trace-element sensitivity.
- Related services: Installation, training, warranty, and multi-year service support are required.
- Period of performance: Duration and end point are not specified; the scope includes system installation and multi-year support.

### Description

McMaster University and the Canadian Centre for Electron Microscopy require one laboratory µXRF system for non-destructive, large-area elemental mapping with micrometre-scale resolution and trace-element sensitivity. Requirements include a high-brightness microfocus source, selectable excitation energies, focusing optics with a spot size of 8 µm or less, and a high-vacuum environment supporting light-element and depth-selective analysis. Installation, training, warranty, and multi-year service support are included. McMaster University intends to award the contract to Systems for Research Corp. through an Advance Contract Award Notice; other suppliers may submit a Statement of Capabilities Form by the closing date.
