| Resumen |
Four types of chemically sensitive field-effect transistors (CHEMFET) detector systems were evaluated for their ability to determine 1-10ppb organophosphorous compounds or pesticides with a response time of <10s, complete reversibility in 30s, a shelf-life of 6 months and an operational life of 104 days of continuous use. Performance assessments indicated that the work-function and galvanostatic CHEMFET were the best candidates at present. The enzyme-coupled and catalytic CHEMFET did not meet specifications. The integration of chemically sensitive polymers with the field-effect transistor structure was considered. |
