## Description

FBO ANNOUNCEMENT: PRESOLICITATION NOTICE, NOTICE OF INTENT ACTION CODE: Presolicitation Notice SUBJECT: Sole source – Replacement Cesium Source Head for a Secondary Ion Mass Spectrometry Instrument RESPONSE DATE: 11/07/26 DESCRIPTION: The National Institute of Standards and Technology (NIST) relies on a time-of-flight secondary ion mass spectrometry (ToF-SIMS) instrument. Currently, the Cesium Source Head is non-functional and requires urgent replacement to restore operation. The National Institute of Standards and Technology (NIST) intends to negotiate on a sole source basis, under the authority of FAR Part 12.102(b) with ION-TOF USA, Inc located in Chestnut Ridge, New York, for this replacement equipment. Sole Source justification is based on the following: Market research has shown that ION-TOF is the sole source for replacement equipment for this NIST owned Secondary Ion Mass Spectrometry Instrument instrument. ION-TOF has stated in writing stated that: “ION-TOF USA, Inc. is the only company authorized and capable of offering service and spare parts for the IONTOF range of surface analysis equipment including the TOF-SIMS IV instruments.” NAICS code for this requirement will be 334516– Analytical Laboratory Instrument Manufacturing with a small business size of 1000 employees. No solicitation package will be issued. This notice of intent is not a request for competitive quotations; however, interested parties who regard themselves as capable of fulfilling these requirements are invited to submit responses to the Government for consideration. Responses received by 1:00AM EST on 11/07/26 will be considered by the Government.
