A flame ionization detector (FID) is a device commonly used in chromatography for the detection of volatile organic compounds (VOCs).
It is a highly sensitive detector, capable of detecting levels of VOCs as low as parts per trillion. It works by passing a sample of the gas to be analyzed through a flame, where it is oxidized and ionized.
The ions formed are then detected by an electron multiplier, which amplifies the signal before it is sent to the recorder.
The flame ionization detector was invented by two scientists, E.A. Parr and J.C.F. Bende. It was initially used to measure levels of hydrocarbons in petroleum products.
Since then, it has become increasingly popular for the analysis of VOCs, as it is both sensitive and selective. It is widely used in the petrochemical, environmental, and pharmaceutical industries.
The FID is made up of several components, including a flame, an ionization chamber, an electron multiplier, and a recorder.
The flame is usually a hydrogen-air combustion flame, which is used to heat the sample and oxidize it. The ionization chamber is where the sample is ionized and the electrons are collected. The electron multiplier is used to amplify the signal, before it is sent to the recorder.
The FID is a powerful and reliable tool for the detection of VOCs. Its sensitivity and selectivity make it an ideal choice for environmental monitoring, petrochemical analysis, and other applications. Its simplicity and affordability have also made it one of the most popular detectors in use today.
The Global Flame Ionization Detector market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
TRACE-GAS Incorporates Flame Ionisation Detection (FID) into its Technology Portfolio to Broaden its Application in Gas Analysis. The technology platform TRACE-GAS FID is intended for highly accurate measurement of organic hydrocarbons (VOC, THC, and methane).
The ionisation of carbon atoms that are bound organically in a hydrogen flame serves as the basis for the measurement concept. This makes it possible to determine the mass concentration of THC or CH4 in a process or sample gas.
Extreme linearity over a broad concentration range and a very high dynamic range distinguish the FID technology from other sensor principles and make it suitable for a wide variety of applications.
A small structure and versatility were given considerable consideration during the sensor’s design process. The simultaneous measurement of THC and CH4 was made possible by the implementation of a dual-channel measurement system in the smallest possible size, all in the service of this purpose.
The dual system is optimal for the diverse application areas of the technology platform since it allows for the monitoring of non-methane hydrocarbons (NMHC) concentration.
Flame ionisation detection is an ideal addition to current systems, such as those used in gas chromatography, due to its small and lightweight sensor system architecture. The modular nature of the sensor technology makes the connection and integration simple to implement.
In automotive applications where flame ionisation is mandated as the reference method for measuring total hydrocarbon (THC) in exhaust gas, the TRACE-GAS FID sensor technology has already been put to use.
In the context of PEMS measurements, the main emphasis here is on the mobile application of the entire measuring system. Low-voltage operation and low power consumption are especially beneficial for transportable solutions.
In order to reliably measure the hydrocarbon concentration, measuring equipment based on the FID principle are widely employed in other industries, such as the semiconductor industry and for applications in landfill leak monitoring and industrial plants.
