Mississippi State University is requesting sole-source purchase authorization for a WRK String Spectrometer Instrument and WRK Flight-line Sample Collector System with parts kits, weather and speed kits, and associated components under Notice 267-006, with the sole-source objection window closing July 22, 2026. MSU has determined the WRK system is the only equipment capable of performing string data collection and analysis for swath-width measurement in aerial application research; while alternative spectrometer instruments exist, none are designed for the critical string data collection methodology required.

The equipment will support multiple sponsored research projects requiring data collection for unmanned/uncrewed aerial application systems, specifically effective swath width, droplet spectrum, percentage coverage, and deposition uniformity measurements. MSU has conducted extensive vendor research, reviewed scientific literature, and leveraged prior experience with alternative equipment including the SwathGobbler (Application Insight) and StellarNet PORTA-LIBS System to justify sole-source status.

The estimated cost is $25,695 plus shipping and delivery. MSU considers this price reasonable when compared to comparable portable spectrometer systems available at higher price points.

Objections to sole-source status must be submitted in writing to Jennifer Mayfield, CPPO Director of Procurement Services, with the subject line "Sole Source Objection" and must include detailed explanation and supporting documentation. If MSU determines the commodity can be obtained from another source, the procurement will be withdrawn and submitted to competitive bid; if MSU upholds sole-source determination, the matter will be appealed to the Public Procurement Review Board.
