The Analytical and Chemistry Laboratory provides core capacity for chemical analysis of vector control products and treated materials. The laboratory generates robust chemical evidence to support evaluation of product quality, chemical durability, and performance over time.

By complementing biological efficacy data with precise chemical measurements, the laboratory strengthens AIRID’s ability to deliver comprehensive, policy- and regulator-relevant evaluation of vector control interventions.

Purpose and Role within AIRID

The Analytical and Chemistry Laboratory supports AIRID’s vector control and intervention research by providing quantitative and qualitative chemical analysis of insecticide-treated products and formulations.

It plays a critical role in linking chemical content and integrity with entomological and epidemiological outcomes, ensuring that conclusions on intervention performance are scientifically robust and operationally meaningful.
