Flame Ionization Detector

Our flame ionization detector (FID) is housed within a carefully temperature-regulated chamber to ensure optimal performance. It is specifically designed to detect minute amounts of hydrocarbons in neutral gases. The detection process involves the combustion of Hydrogen and Synthetic Air, creating a flame that consumes the organic components present in the gas being analyzed.

During combustion, these components generate ions that are subsequently collected by an electrode. The resulting weak current is then amplified using a high-gain electrometer and directed towards a data acquisition system for further analysis. To achieve the best possible results, a polarization electrode is connected at the nozzle level, while a collecting electrode with adjustable distance is employed. In addition, when coupled with a methanizer (UMTR unit), our FID is capable of detecting traces of CO and CO2 as well. The methanizer serves to convert these trace amounts of CO and CO2 into methane through a catalytic reaction that takes place in a specially designed reactor. This conversion occurs at a temperature of approximately 350°C in the presence of excess Hydrogen. With precise temperature control and an optimized flow rate, the methanizer achieves an efficiency level close to 100%.

When supplied with high purity gases, our FID exhibits an impressive detection threshold of up to 1 ppb (parts per billion), enabling the identification and quantification of extremely low levels of target compounds.
