VOC - 350 Ultra Portable Volatile Organic Gas Analyzer

The VOC-350Ultra Portable VOCs Detector is a very lightweight VOCs analyzer based on the FID principle. It can be operated with one hand. It is equipped with three detectors, namely a Flame Ionization Detector (FID), a Photoionization Detector (PID), and a Hydrogen Chloride (HCL) detector. It can measure inorganic odor gases such as HCL and HF, to which the single/double detectors mentioned above have no response, boasting ultra-comprehensive measurement performance.

Principle of Flame Ionization Detector (FID)

The Flame Ionization Detector (FID) is a typical destructive, mass - type detector. It uses the flame generated by the combustion of hydrogen and air as the energy source. When organic compounds enter the flame combusted by hydrogen and oxygen, they undergo chemical ionization at high temperatures. This ionization produces ions whose quantity is several orders of magnitude higher than the base current. Under the directional action of a high - voltage electric field, an ion current is formed. The weak ion current is amplified by a high - resistance amplifier to become an electrical signal that is proportional to the amount of organic compounds entering the flame. Therefore, the quantitative analysis of organic compounds can be carried out according to the magnitude of the signal.

The Flame Ionization Detector features a simple structure, excellent performance, high stability and reliability, rapid response, accurate detection, and a wide linear range. The outstanding advantage of FID is that it responds to almost all organic compounds. Especially, it has a high sensitivity to hydrocarbons, and the response is proportional to the number of carbon atoms. It is insensitive to inorganic substances such as H₂O, CO₂, and CS₂, and is also insensitive to changes in gas flow rate, pressure, and temperature.
