Attachment 1 Specifications Mass Spectrometer.pdf

This attachment provides specifications for a mass spectrometer and elemental analyzer system. The specifications call for a high-performance isotope ratio mass spectrometer with a continuous flow interface, an elemental analyzer for simultaneous carbon, nitrogen, and sulfur isotope ratio analyses interfacing with the mass spectrometer. Additional requirements include a dedicated isotope system for carbon and oxygen analysis of CO2 in septum-sealed 12ml vials and automated switching of amplifier resistor for analysis of minor isotope abundances over 99%. The system must also automatically handle six monitoring gases and five inlets with 100V amplification and provide gas ionization performance of 1,100 molecules/ion and a mass resolution of 110 m/Δm. The specifications also state the analyzer must be made of stainless steel and include an autosampler with a 12ml vial rack.

The related federal contract opportunity is a solicitation from the Department of Agriculture Agricultural Research Service Field Research Implementation and Information Delivery Plains Area seeking offers for the mass spectrometer and elemental analyzer system described in the attached specifications. The solicitation number is 12805B23Q0786 and is labeled as a mass spectrometer opportunity.
