This Request for Proposals (the “RFP”) is an invitation by the University of Ottawa (the “University”) to prospective proponents to submit proposals for an Inductive Bridge for Anisotropy of Magnetic Susceptibility Measurement, as further described in Appendix D (RFP Particulars) Section A (the “Deliverables”).
THE DELIVERABLES
The requested instrument is an Inductive Bridge for Anisotropy of Magnetic Susceptibility Measurement in rocks. The instrument will be housed in the new Ore Deposit Petrology Laboratory (ODPL) at the University of Ottawa. This laboratory is dedicated to the petrological characterization of ore mineralized rocks, with specific capacity in reflected light characterization, sample visualization and microstructural analysis. The aim of the current project is to apply the AMS technique to quantifying petrofabic in a wide range of rock types associated with base- and precious metal mineralisation, to better understand ore deposit forming processes. The instrument will complement other state-of-the-art microscopy tools in the ODPL.
The instrument should be capable of rapid and precise measurement of magnetic susceptibilty and AMS. The instrument should be automated, such that the sample orientation does not have to be changed manually during a single measurement. The instrument should be capable of measuring susceptibility and AMS in different magnetic fields. The instrument should also be capable of measuring low field magnetic susceptibility at high and low temperature, to better facilitate magnetic mineralogy characterisation. It should be possible to fully control the instrument with a computer and there should be bespoke software available to support data processing and interpretation.
It is expected that the successful proponent provides a bespoke training at the time of equipment delivery and on-site installation. Remote assistance and trouble shooting support should be available when required. The equipment must comes with a minimum of 1 year full warranty.
Mandatory Technical Specifications Requirements:
1.0 - Inductive Bridge for Anisotropy of Magnetic Susceptibility Measurement
1.1 - The instrument should be able to measure anisotropy of magnetic susceptibility (AMS) fabrics rapidly and precisely, i.e., one full measurement including bulk susceptibility to be completed in minutes, with a minimum requirement of <10 minutes, with a sensitivity on the order of >10-6 SI
1.2 - The instrument should be automated, such that sample orientation does not need to be changed manually during a single measurement.
1.3 - The instrument must be capable of measuring AMS fabrics in variable magnetic fields, over a range <10 to >700 A/m, also automatically
1.4 - The instrument must be able to measure magnetic susceptibility at different temperatures, over the range -190-700 °C, either as is or with a bespoke attachment or attachments, in order to characterise magnetic mineralogy
1.5 - The instrument must be capable of automated zeroing
1.6 - It must be possible to operate the instrument by computer and there should be bespoke software provided to support instrument operation as well as data processing, interpretation and graphical representation. In particular, software provided should support automatic AMS measurements and facilitate calculations and plotting of various AMS parameters as well as export of dataplots to multiple graphic formats.
2.0 - Other
2.1 - All accessories required to operate the instrument plus attachments, if relevant, should be provided, e.g., sample holders, screws, screwdrivers.
2.2 - Must include minimum of 1 full year standard manufacturer’s warranty.
2.3 - Must include installation and on-site training.
