An autonomous flame ionization detector for emission monitoring

Abstract

Abstract. Reliable and very sensitive detection of hydrocarbons can be achieved with a flame ionization detector (FID). Due to the required complex gas infrastructure for the operation of an FID, these devices have not been implemented as true field devices yet. Miniaturization by using ceramic multilayer technology leads to a strong reduction of gas consumption and allows autonomous operation of the FID with gas supply by electrolysis and without external gas infrastructure. Therefore, this research enables the use of the FID in the field. Characterization of this miniaturized FID reveals a performance comparable to conventional FIDs.

Cavity-Enhanced Raman Spectroscopy for Detection of Trace Gaseous Impurities in Hydrogen for Fuel Cells

“…GC 10 has high sensitivity and selectivity, but the device is bulky, expensive, and cumbersome maintenance is needed frequently. Besides, the gas will be consumed by the GC's detector with high sensitivity, for instance, flame ionization detector (FID) 11 and flame photometric detector (FPD). 12 Electrochemical sensors 13 have high sensitivity, small volume, and low cost, but they suffer from aging, sensing material poisoning, and crosssensitivity for different gases.…”
