Extensive and flexible capacity and facilities allowing rapid turnaround

Cross-functional scientists dedicated to excellence in characterizing standard and non-standard substances

A comprehensive suite of physicochemical tests, including all routine general and hazardous assessments

It is essential to characterize and understand the basic physicochemical properties of your Pure Active Ingredient (PAI) or Technical Grade Active Ingredient (TGAI). All active ingredients require their physicochemical properties to be characterized. we have been helping customers to assess and characterize their active ingredients for over 50 years. With vast experience working on difficult to handle substance, we can help you with both complex and simpler tests tailored to your requirements.

How to establish basic physicochemical parameters in a timely manner

Common tests for basic physicochemical parameters of active ingredients are straightforward to run. However, some active ingredients can be difficult to handle and need unique approaches. For example, active ingredients with high volatility, poor solubility or which require a specific detection type – all need a tailored approach. 

Our Capabilities

Extensive experience of standard and difficult-to-handle active ingredients 

Labcorp's combination of extensive facilities and dedicated analytical chemists ensures your needs are met, no matter how complex the active ingredient. A suite of the standard physicochemical tests for pesticide active ingredients are available:
