Summary (Newest Update)

Background The Centers for Disease Control and Prevention (CDC) intends to award a sole-source purchase order to TSI Incorporated, the only company that manufactures a Scanning Mobility Particle Sizer meeting the specifications required for inhalation research. TSI Inc. is a US-based instrument manufacturer known for supplying high-performance laboratory instrumentation to various sectors including government and research institutions. The procurement aims to enhance the understanding of inhalable particle sizes and their health effects, thereby supporting gold standard scientific research. Work Details The contract involves the purchase of a Scanning Mobility Particle Sizer, which will enable the Health Effects Laboratory Division, Physical Effects Research Branch to obtain particle size distributions for test dusts, powders, droplets, and aerosol samples within the 10 to 800 nm size range. The specific equipment includes: - Scanning Mobility Particle Sizer capable of measuring particles from 10 to 800 nm. - Advanced Aerosol Neutralizer (Soft X-ray) Model 3088 designed specifically for use with the Scanning Mobility Particle Sizer. - Shipping costs associated with delivering these items to NIOSH Morgantown campus. Period of Performance 06/01/2026 – 05/31/2027 Place of Performance NIOSH Morgantown: 1095 Willowdale Road, Building L, Mail Stop 2027, Morgantown, WV, 26505 – Laboratory 3614. Bidder Requirements Offerors must comply with established HHS Information and Communication Technology (ICT) accessibility standards as per Section 508. They are required to submit an Accessibility Conformance Report or HHS Section 508 Accessibility Conformance Checklist detailing how their products meet these standards. Incumbent Analysis (see Incumbents section for more detail) This notice appears to have a confirmed incumbent, with prior CDC contracts awarded to TSI for Scanning Mobility Particle Sizers and associated aerosol neutralizer configurations (e.g., TSI 3088 Advanced Aerosol Neutralizer), including awards valued at $203,425 (08/30/23–11/22/23) and $101,695 (04/19/23–06/30/23). The current requirement similarly calls for a Scanning Mobility Particle Sizer covering the 10–800 nm range along with an Advanced Aerosol Neutralizer (Soft X-ray) model 3088, suggesting continuity in the same instrument platform and intended inhalation research use.

Current: Posted: June 15, 2026, 3:52 p.m. EDT This is a notice of intent to award a sole-source contract using simplified acquisition procedures and is not a request for competitive quotes. The Centers for Disease Control and Prevention (CDC) intends to award a sole-source purchase order using the procedures at RFO 12.102(a) as it has been deemed that only one source is available to meet this specific requirement due to the intended vendor, TSI Incorporated being the only company making a Scanning Mobility Particle Sizer that meets the specifications needed for inhalation research. The statement of work and specifications are attached. This notice of intent is not a request for competitive quotations. Any party who believes they can perform this requirement should submit a capability statement for consideration by the government. A determination by the government not to compete this proposed contract based on responses to this notice is solely within the discretion of the government. Information received by the government as a result of this notice will be considered solely for the purpose of determining whether to conduct competitive procurement. The government will not be responsible for any costs incurred by a party who responds to this notice. A party may identify their interest and submit a capability statement by 4pm (EST) on 24 June 2026. Responses, including questions about this notice, should be sent via email to Contract Specialist, Aminah Gary at uuu0@cdc.gov.
