Potentiometrischer NH3Sensor auf Basis NH4 leitender ...

Ziel dieser Masterarbeit war der Aufbau eines kostengünstigen NH 3Sensors mit Hilfe unkomplizierter Methoden. Durch Einsatz NH 4 +leitender Zeolithe sollte ein potentiometrischer NH 3Gassensor realisiert werden. Am Lehrstuhl wurden schon erfolgreich planare zeolithbasierte Sensoren zur Detektion von CO 2 hergestellt.[1] Als Festelektrolyt wurden hier mit Ptbeladene Zeolithe des Typs

NOx Sensors DieselNet

Abstract: Automotive NOx sensors are primarily of the amperometric type, with two or three electrochemical cells in adjacent first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. Commercial sensors, available from several suppliers, are used for the control of NOx adsorber and SCR aftertreatment.
