About this file

This technical specification outlines requirements for a standalone liquid nitrogen generator to support a mass spectrometer instrument. The generator must be capable of producing up to 35 L/min of analytical-grade nitrogen gas at a maximum pressure of 116 psi, with outlet fittings and redundant moisture removal systems. It will operate continuously to support research and analysis at the Rocky Mountain Regional VA Medical Center in Aurora, Colorado. Responses are due by January 11, 2024 at 4:00 PM for this solicitation issued by the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 19. The specification provides detailed performance and design requirements for purifying, compressing, and delivering nitrogen gas to analytical instrumentation.
