NAICS: 334516
Scope: Federal

OPQR has a requirement to obtain an advanced dynamic light scattering detector to enhance characterization capabilities for emerging pharmaceutical products and complex biologics.

For a quoter's detector to be deemed acceptable, the following salient characteristics shall be met: QELS Dynamic Light Scattering Detector: Real-time hydrodynamic radius measurement capability that operates inline with Field-Flow Fractionation separation to provide simultaneous size characterization as samples elute from the FFF system.

Compatibility with Existing FFF System: Must be fully compatible with and integrate seamlessly into the existing FFF system, including hardware connections, software integration with chromatography software, and synchronized data acquisition with existing MALS detectors.

High-Sensitivity Detection: Capable of measuring hydrodynamic radii across a wide dynamic range from approximately 10 nm to 1000 nm to accommodate diverse sample types including proteins, protein aggregates, liposomes, and lipid nanoparticles.

Orthogonal Size Validation: Provides diffusion-based size measurements that complement separation-based FFF analysis, enabling validation of particle size distributions and detection of sub-populations or aggregates that may not be fully resolved by separation alone.

Data Correlation and Analysis: Integrated software functionality that enables direct correlation between molecular weight data from MALS detection and hydrodynamic size from DLS detection to provide comprehensive analysis of absolute molar mass, root-mean-square radius, and hydrodynamic radius.

Data Output: Generates validated, audit-trail-compliant data files suitable for regulatory submissions and scientific publications, with full integration into existing software platform for unified data pro...

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
Check the set-aside listed above and confirm your business actually qualifies for it before you spend time on a proposal. See our guide to set-asides if the category is unfamiliar.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
