The Department of Defense, through the Naval Research Laboratory (NRL), is seeking sources for an Inductively Coupled Plasma Mass Spectrometry (ICP-MS) system capable of elemental analysis with sensitivity down to parts per trillion (ppt). This procurement aims to enhance NRL's analytical capabilities, which are currently limited by existing equipment, and is critical for fulfilling obligations to external sponsors such as DARPA. The ICP-MS system must include essential components such as a Sample Introduction System, Matrix Dilution, a Multi-Quadrupole Mass Spectrometer, a Chiller System, and Regulators for Reactive Gases and a Vacuum Pump, all meeting specific performance standards. Interested parties are encouraged to submit their responses, including company information and technical capabilities, to Elizabeth Maranto at elizabeth.m.maranto.civ@us.navy.mil by the specified deadline, as this is a Sources Sought Notice for market research and planning purposes only.
