Comparison of standard CIPAC method with a miniaturised protocol for determining insecticide content incorporated in long-lasting bed nets (LLINs). The sample size has been reduced from 400 cm2 (2 g) to ~ 40 cm2 (0.2 g) to enable a small volume of extraction solution (5 vs. 50 used in the standard CIPAC methods) for permethrin12 and pyriproxyfen13 respectively.
