Abstract
The performance of a halogen selective aerosol alkali flame ionization detector (AFID) is presented. A constant delivery of desolvated alkal i salt aerosol is introduced into the detector in the form of dual hyd rogen gas names, The problems of enhancement-source vaporization and c ontamination, which occur in fixed alkali salt versions, do not occur with the presented aerosol design. Detection limits range from 321 pgI /sec to 450 pgI/sec and 6.7 ngBr/sec to 15 ngBr/sec. Selectivity ratio s were 10(3) gI/gC and 10(2) gBr/gC using an 100 ppm potassium chlorid e as the alkali salt solution.
