Aethalometer- Supply Arrangement (SA) E60PV-19EQUI

Environment and Climate Change Canada has a requirement for an aethalometer to measure BC and BrC absorption for laboratory and field studies.

Mandatory Technical Criteria:

The following requirements are the mandatory technical evaluation criteria which will be evaluated during the Bid Evaluation. In addition, the Contractor will be required to meet all of the mandatory technical requirements for the duration of the Contract. Bidders are requested to cross reference the mandatory technical criteria in a concise format by using page, paragraph(s) & sub-paragraphs as applicable to their supporting technical documentation.

Item        Criteria        Reference to substantiation in the Technical Bid
