University of Alberta - Advanced Contract Award Notice / Notice of Proposed Procurement - Vocus Chemical Ionization Time-of-Flight Mass Spectrometer (Vocus CI-ToF-MS System)

The University of Alberta has issued a pre-solicitation notice for the single source acquisition of a Vocus Chemical Ionization Time-of-Flight Mass Spectrometer system from Aerodyne Research Inc. This high-performance system is essential for departmental research requiring real-time, direct atmospheric sampling of trace gases and aerosols at sub-parts-per-trillion limits. Aerodyne is identified as the sole provider capable of meeting the necessary scientific criteria, including bipolar ion measurement, concurrent gas and aerosol-phase analysis, and high mass resolution exceeding 10,000 Th/Th. The procurement, identified by solicitation number AB-2026-06561, emphasizes the need for field-deployable mobility and rapid ionization mode switching between PTR and CI. The notice was posted on September 28, 2026, with a response deadline of October 6, 2026. The acquisition is managed by the University of Alberta, with Satinder Atwal serving as the primary point of contact for the procurement process.
