Abstract
Microelectrodes for measuring nitrogenous compounds (${NH_4}^+$, ${NO_3}^-$) that were applied into the microfluidics chips was investigated, and the effect of temperature was especially examined. In this specific research, microelectrodes were first calibrated to check the function, and then microsensor that was combined microelectrode with microfluidic chip was re-calibrated. Experimental results showed that there are no change in the function between microelectrode and microfluidic chip. The electro motive force (EMF) for the ${NH_4}^+$ microsensor was similar to the one theoretically calculated from Nernst equation, but the EMF for ${NO_3}^-$ showed minor change.
