GLP Fluorometry Lab and Upcoming Conferences | | |
Greetings!
As we kick off 2026, we are excited to share a behind the scenes look at one of the most unique capabilities in our agrochemical services portfolio, our GLP fluorometry laboratory, which just surpassed a major milestone. You will find the full spotlight at the bottom of this message, and it is worth the scroll.

Rooted in Quality: Preventing Deviations Before They Sprout
Thursday, Jan. 29, 2026 | Investigative Techniques & Troubleshooting Session, 7:45 to 10 a.m. EST| Room: Grand B
Deviations happen in GLP field trials — but many don’t have to. Quality Manager Jennifer Cypher will explore how ambiguity, assumed knowledge, and unrealistic instructions in protocols and SOPs create preventable deviations. She offers strategies teams can use to write documents that are clear, practical, and built for real-world field conditions.
Get in touch with Jenn.

Spray Drone End Users Conference 2026
January 25 to 29 | Kansas City Convention Center
Building off our success in completing the first GLP spray drift studies with a drone, Aaron Rice and Brent Toth will be attending this year's Spray Drone End Users Conference to share what we've been practicing and learning about the latest technology, compliance standards, and real-world innovations in this exciting field as it applies to agriculture. If you're planning to attend, let us know!
Contact Aaron or Brent.
| | | CAPABILITIES SPOTLIGHT: GLP Fluorometry Lab | | |
The Stone Fluorometry Lab concluded 2025 by surpassing the milestone of 15,000 fluorometry samples analyzed!
Over the past five years we have conducted 13 spray drift deposition studies using tracer dyes, totaling more than 200 individual study treatments. Our in-house Good Laboratory Practices (GLP) compliant fluorometry laboratory is supported by robust SOPs, a rigorous QA/QC process, meticulous documentation, and highly trained and experienced staff.
The use of fluorescent tracer dyes for drift deposition studies is approved in EPA’s Spray Drift Test Guidelines 840.1200, and endorsed in spray drift testing standards from the American Society of Agricultural and Biological Engineers ASABE S561.1 and the International Organization for Standardization ISO 22866. Fluorometric analysis of drift samples conducted in accordance with GLP can reduce analytical turnaround time and study costs compared to active ingredient residue analysis, while maintaining data integrity and regulatory defensibility.

If you are considering a spray drift study for your active ingredient, we encourage you to contact us to learn more about the Stone Fluorometry Lab and the seamless integration of field operations and laboratory analysis for a high quality, cost-effective solution that meets the data expectations of regulatory agencies.
