Field Speciation of Ultrafine to Coarse Particulate
AI Overview
This SBIR seeks a portable field device that rapidly characterizes ultrafine to coarse particulate composition—including carbonaceous, metal, and biological materials—to replace laboratory analysis and enable real-time exposure monitoring for military personnel in hazardous environments.
This summary is AI-generated from the official solicitation.
Key Details
Official Description
This SBIR topic aligns with the DHA Environmental Exposures Toxic Injury Prevention Roadmap, specifically focusing on enhanced tools and assessment methodology for acute and chronic exposure to military-relevant chemicals, materials, and hazards.
The DoW requires the capability to comprehensively characterize particulate composition in situ in the field to replace current methods which require samples to be collected and sent to a reach back laboratory. Particulate exposure is correlated with e...
Change History
Field Speciation of Ultrafine to Coarse Particulate
**Changes to Q&A:** - **New Q1**: Added eligibility question on STTR vs. SBIR project type (unanswered) - **Renumbered questions**: Previous Q2-Q6 shifted to Q2-Q7 - **Incomplete answer**: Q7 (formerly Q6) on size binning requirements still cuts off mid-response regarding expected size resolution
Field Speciation of Ultrafine to Coarse Particulate
Added 5 new Q&As: auto-calibration required (no consumables); device size corrected to 2,000 cubic inches; both battery and 120V AC power preferred; preconcentration acceptable with field analysis automation; size binning resolution question remains pending.
Field Speciation of Ultrafine to Coarse Particulate
**Size and weight constraint clarified: "cubic feet" changed to "cubic inch"** This is a significant tightening of the device size requirement. The prototype must now fit within 2000 cubic inches (not cubic feet), which is approximately 1/13th the original allowable volume. This substantially increases the engineering challenge for miniaturization and may impact feasibility assessments or design approaches applicants should propose.
Field Speciation of Ultrafine to Coarse Particulate
Q1 answered: Airborne particles specified; proposers must justify particle quantity/concentration based on end-user scenario and technology requirements. Q2 answered: Option B (discrete size binning with composition percentages) is mandatory for Phase I, not just Option A.

Status changed from Pre-Release to Open
Field Speciation of Ultrafine to Coarse Particulate
**New Q&A Clarifies Particle Analysis Requirements for Phase I:** The clarification distinguishes between two technical approaches: real-time chemical classification of individual particles (Option A) versus adding discrete size binning and composition reporting per bin (Option B). Applicants should clarify in proposals whether their Phase I design will include size binning or if chemical classification alone suffices, as the Q&A indicates Option A may be sufficient but leaves final requirement determination pending additional agency response.
