PROCESS:
Suppliers that consider their equipment functional, successfully tested, readily available and fully compliant to the ACAN minimum requirements may submit, in writing, a statement of specifications to the contact person identified in this Notice, on or before the closing date of this Notice. In the statement of specifications, the supplier must unequivocally demonstrate how their equipment, at minimum, equals, or exceeds the stated requirements.
If no other supplier submits a statement of specifications, on or before the closing date of this Notice, the competitive requirements of the University of Ottawa will be considered having been met. Following notification to any suppliers not successful in unequivocally demonstrating that their statement of specifications equals or exceeds the requirements set out in this Notice, the contract may then be awarded to the pre-identified supplier.

Closing Date: April 8, 2020, at 3:00:00 P.M. Eastern Standard Time
INTENDED USE:
In the molecular magnetism field, magnetic characterization of new classic coordination compounds and organometallics is essential towards fundamentally understanding how specific magnetic phenomena arise. Furthermore, this characterization allows us to innovate new experiments and systems with further enhanced
properties.
The study of Single-Molecule Magnets (SMMs) is of importance towards the improvement of high-density information storage devices and quantum computing systems. The study of these systems can also be combined with other characterization techniques to combine different physical properties (e.g. luminescence, single-molecule magnetism, etc.) and potentially isolate multi-functional materials.
In order to probe these very subtle yet powerful properties, state-of-the-art technologies are required. The research program requires sensitive instrumentation for measuring the physical and magnetic properties as a function of applied magnetic field, temperature, pressure and/or light.
Therefore, the University of Ottawa intent to acquire a Magnetic Property Measurement System (MPMS), with a 7 Tesla cryogen-free magnet, and the ability to measure the magnetic properties of materials with a Superconducting Quantum Interference Device (SQUID) to have the ability to perform the above mentioned researches.

Justification of Pre-Selected Supplier:
Supplier: Quantum Design Inc., 10307 Pacific Center Court, San Diego, CA, 92121, United States
Justification:
Many instrument manufacturers can provide systems which are designed to only measure a single property at a time (e.g. optical, electrical, magnetic, etc.). While these systems are enough to measure the properties around which they are designed, they are unable to measure multiple properties. Furthermore, they are not able to simultaneously measure the effects of multiple different parameters on a given sample (e.g. the effect of temperature and/or pressure on the magnetic properties). To the best of our knowledge, Quantum Design Inc. is the only company capable of providing a system which combines multiple different measurement options, ranging from magnetism, pressure, optics, and more. Additionally, Quantum Design Inc. also offer options to see how specific physical properties influence others, through simultaneous application and measurement (e.g. light- or pressure-dependent magnetic measurements).
