RFI Attachment B – In Situ Dissolved-Gas Mass Spectrometer (MASSP):

Instrument SpecificHardware & Performance

This table contains Instrument Specific Hardware & Performance Requirements for a mass spectrometer (MASSP) attached to the Regional Scale Nodes (RSN) cabled observatory network. The University of Washington Purchasing Department requests that respondents to this RFI complete and return this form. For those requirements that cannot be met, you may offer an alternative (other*). Respondents may add additional pages, noting the line item, in order to expand upon their responses and comment on the appropriateness of a requirement and/or whether it may be a significant cost-driver.

GENERAL COMMENTS ON MASSP HARDWARE REQUIREMENTS (e.g. reasonableness, significant cost drivers). See RFI for additional information requested:
Specifically, please include the most significant factors (e.g. gas waste) that may limit the combination of frequency of measurements with the length of deployment and what technique(s) you have employed to mitigate those factors.
