Aquatic in-situ sensors

Context

Recent improvements in the design of ion selective electrodes improved signal stability and selectivity. Detection limits can reach the nanomolar ranges. The development of solid-state sensors facilitates the application for in-situ profiling and precision-sampling of lake water.

Applications

Potentiometric electrodes for nitrate, ammonia, pH and CO2 as well as oxygen optodes were adapted for use in a custom-made profiling system with integrated syringe sampler for high-resolution analyses of stratified lakes.
