Fluorescent Derivatization of Nitrite Ions with 2,3-Diaminonaphthalene Utilizing a pH Gradient in a Y-shaped Microchannel

The on-chip derivatization of nitrite ions with 2,3-diaminonaphthalene (DAN) utilizing a pH gradient formed in a Y-shaped microchannel was investigated. Nitrite ions react with DAN at low pH, and strongly fluoresced at high pH. Therefore, a reaction at low pH followed by the addition of a strong alk...
