본 발명은 연관공간(associated volume)(106)에서 아산화질소 (N2O)를 검출하기 위한 전기화학센서(100)에 관한 것이다. 본 발명의 아산화질소 검출능이 향상된 센서는 보다 유용하게 사용될 수 있으며, 보다 효율적이고 감응성이 높고, 내구성이 좋으며, 간편하고, 보다 신뢰성있는 결과를 제공할 수 있다. There is presented an electrochemical sensor (100) for sensing nitrous oxide (N2O) in an associated volume (106), the sensor comprising a primary chamber (110), a secondary chamber (120) being placed adjacent the primary chamber (110), the secondary chamber (120) comprising electrodes for performing electrochemical measurements and furthermore an electrolyte comprising an aprotic solvent. A first membrane (114) and a secondary membrane (124) are permeable to nitrous oxide and may be arranged so as to separate the associated volume (106) from a primary volume (116) within the primary chamber (110), and the primary volume (116) from a secondary volume (126) within the secondary chamber (120), where the primary chamber (110) comprises means for hindering oxygen in passing into the secondary volume (126), and wherein the working electrode (104) comprises indium (In).
