Quick Summary
The Centers for Disease Control and Prevention (CDC), specifically the NIOSH Health Effects Laboratory Division, has issued a Notice of Intent to Sole Source for a TSI MOUDI-II (Micro Orifice Uniform-Deposit Impactors) instrument. This procurement is for inhalation research, requiring a 10-stage particle sizer capable of classifying particles from 0.05 to 18 µm. The CDC intends to award a sole-source contract to TSI Incorporated, citing their unique ability to meet the specific technical requirements. This notice is published under a Total Small Business Set-Aside (FAR 19.5), inviting other small businesses to demonstrate their capability.
Opportunity Details
This Special Notice indicates the CDC's intent to award a sole-source purchase order for a Micro Orifice Uniform-Deposit Impactor (MOUDI) instrument. The justification for sole-sourcing to TSI Incorporated is that they are identified as the only company manufacturing a MOUDI that meets the required wide range of size classification and uniform sample deposition for inhalation research. While this is a notice of intent to sole source, it is published under a Total Small Business Set-Aside (FAR 19.5), inviting other small businesses to demonstrate their capability.
Scope of Work
The requirement is for a 10-stage Micro Orifice Uniform Deposit Impactor (MOUDI) Particle Sizer. This instrument will enable the Health Effects Laboratory Division, Physical Effects Research Branch, to obtain mass-based particle size distributions for various samples (dusts, powders, droplets, aerosols) within the 0.05 to 18 µm range, critical for understanding inhalable particle size fractions and health effects. The vendor is responsible for fulfilling, packing, and shipping the instrument to the NIOSH Morgantown campus. The instrument uses disposable foil collection plates and can utilize membrane filters for Scanning Electron Microscope (SEM) viewing.
Instrument Specifications
The required instrument is a TSI MOUDI II™ Impactor, specifically a 10-stage model. Key features include uniform particle deposition via internal stepper-motor stage rotation, micro-orifice nozzles for sharp cut-size characteristics, and low inter-stage losses. It must size particles from 0.05 to 18 µm based on mass. The government will provide an existing instrument cart, micro balance scale, and a 30 L/min laboratory sample pump. Offerors must comply with HHS Section 508 accessibility standards.
