Opportunity timeline
In plain English
The FDA wants one quasi-elastic light scattering detector for its existing field-flow fractionation and multi-angle light scattering system. The detector must measure hydrodynamic radii from about 10 to 1,000 nm, integrate with current hardware and software, and support data correlation, regulatory audit trails, installation, qualification, training, and technical support. Delivery, installation, and qualification are due within 120 days after award at the FDA facility in St. Louis, Missouri; the order is firm-fixed-price with a 12-month performance period.
About this opportunity
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…
