68 -- STANDARD REFERENCE MATERIAL - ASSORTED SRM GASES SOL 52SBNB6C9023 DUE 121595 POC Marilyn Carter (301) 975-6335/Pauline E. Mallgrave (301) 975-6330 The National Institute of Standards and Technology (NIST) Standard Reference Materials Program (SRMP) has a requirement for the following Standard Reference Materials: (SRM) 1683b at 50 mol/mol and SRM 1684b at 100 mol/mol - Nitric Oxide in Nitrogen; SRM 2730 at 5 mol/mol and SRM 2731 at 20 mol/mol - Hydrogen Sulfide in Nitrogen; SRM 1679c at 100 mol/mol - Carbon Monoxide in Nitrogen; SRM 2619a at 0.5 mol/mol, SRM 2620a at 1 mol/mol, and SRM 2621a at 1.5 mol/mol - Carbon Dioxide in Nitrogen; SRM 1659a at 10 mol/mol, and SRM 2750 at 50 mol/mol, and SRM 2751 at 100 mol/mol - Methane in Air. The SRMP also requires as option items to be awarded in FY 97 the following: SRM 2629a at 20 mol/mol - Nitric Oxide in Nitrogen; SRM 2635a at 25 mol/mol, SRM 2636a at 250 mol/mol, SRM 2637a at 2500 mol/mol, and SRM 2638a at 5000 mol/mol - Carbon Monoxide in Nitrogen; SRM 2660 at 100 mol/mol - Oxides of Nitrogen in Air, and SRM 1662a at 1000 mol/mol and SRM 1663a at 1500 mol/mol - Sulfur Dioxide in Nitrogen. These gas mixtures shall be used as primary gas Standard Reference Materials certified as to composition by the National Institue of Standards and Technology-- Detailed specifications and quantity requirements shall be available with the soliciation. Delivery Required 90 days after contract award--NIST anticipates the possibility of multiple awards for this requirement--FOB Destination, Gaithersburg, MD--All qualifided sources may submit a proposal which shall be considered by the agency--Requests for the solicaitation package should be in writing to the above address.
