Abstract
A micro ammonia sensor, consisting of an ISFET covered with a dry membrane which is made from nonactin and substituted poly-.gamma.-methyl-L-glutamate (PMG) is described. The gate output voltage of the micro ammonia sensor increased with NH4OH addition. The response time of the sensor was 2 min at 30.degree. C, and the sensor exhibited superior selectivity for NH4+ compared to a pH sensitive ISFET.This publication has 3 references indexed in Scilit:
