As global regulatory scrutiny intensifies, these nonselective herbicides, which are widely used in agricultural and industrial settings, require precise and reliable monitoring. Because these compounds can migrate into agricultural runoff, groundwater, and irrigation systems, robust testing is essential to verify product quality and support supply chain compliance.

Historically, testing for Paraquat and Diquat has been complex and often dependent on time-consuming derivatization processes. Columbia Laboratories’ expanded analytical capabilities streamline testing and reduce unnecessary processing bottlenecks, providing clients with greater efficiency and a more cost-effective solution.

Regulatory bodies such as the U.S. Environmental Protection Agency (EPA) and European Food Safety Authority (EFSA) enforce strict Maximum Residue Limits (MRLs) for Paraquat and Diquat. Exceeding these thresholds can lead to costly product recalls, regulatory penalties, and long-term damage to brand reputation.

Our expanded Polar Pesticide testing capabilities provide the comprehensive analysis needed to help agricultural producers, food manufacturers, ingredient suppliers, and exporters meet domestic and international compliance requirements.

This development underscores our continued investment in innovation and our commitment to remaining at the forefront of analytical science. Columbia Laboratories provides practical, science-driven solutions that help clients navigate evolving food safety and regulatory requirements with confidence.

Protect your brand, strengthen supply chain integrity, and maintain market access with Columbia Laboratories.
