This is a Request for Information (RFI) for market research purposes, not a solicitation. The EPA is seeking information from qualified sources regarding a GC-MS/MS system for analyzing PFAS in air, intended for use in EPA Region 9. Interested parties are invited to submit a response. The government will not reimburse any costs incurred in responding, and this RFI does not commit the government to a contract. Not responding does not preclude future participation in any subsequent solicitation.
