66 -- TIME-OF-FLIGHT MASS SPECTROMETER FOR MATRIX-ASSISTED LASER DESORPTION/IONIZATION (MALDI) ANALYSIS OF SYNTHETIC POLYMERS SOL 52SBNB6C9187 DUE 072996 POC Linda Shariati (301) 975-5053 The National Institute of Standards and Technology (NIST) intends to procure a time-of-flight mass spectrometer for matrix-assisted laser desorption/ionization (MALDI) analysis of synthetic polymers. The Contractor shall provide a fully-operational device to perform matrix-assisted laser desorption/ionization mass spectrometry. The device must measure mass using the time-of-flight method. It shall function in both linear and reflectron (ion mirror) modes. The MALDI shall have delayed extraction capabilities for improved resolution and have post-source decay capabilities to study analyte fragmentation. The device is to be used to study synthetic polymer molecular weight distribution, primarily for NIST Standard Reference Material certification, and shall be compatible with this purpose. The system shall be versatile, amenable to upgrade with new technologies, and demonstrate superior resolution and sensitivity. The Contractor shall provide installation/set-up and on-site training of users as well as a warranty of at least one year including parts and labor. NIST requires delivery within 120 days of contract award - FOB Destination. The Request for Proposals (RFP) will be available approximately fifteen days after publication of this announcement and responses will be due approximately thirty days after issuance. All responsible sources may submit a proposal which will be considered by the agency. All requests for the RFP must be in writing to the above mentioned address. (0171)
