Nv. Isakova et al., ION-SELECTIVE FIELD-EFFECT TRANSISTORS WITH PLASTICIZED MEMBRANES - ASENSOR FOR TETRAFLUOROBORATE IONS, Journal of analytical chemistry, 53(1), 1998, pp. 65-67
An ion-selective field-effect transistor (ISFET) for BF4 with an ion-s
ensitive poly(vinyl chloride) membrane and a protective polymer membra
ne was prepared. The ISFET was insensitive to pH changes within the ra
nge 2-9. The service life of the sensor is no shorter than three month
s.
