Hydrocarbons, which form the basis for studying organic chemistry, have different sensor technologies for detecting them. The technologies include flame ionization, gas chromatography, infrared, catalytic and photo-ionization. You can refer technologies to hydrocarbon analyzers. Here is everything you need to know about them.
Types of Hydrocarbon Analyzers
- Photo-ionization and Infra-red Sensors
Both of these sensor technologies are useful in low range monitoring of hydrocarbons. They are less useful in areas with mixtures and higher concentrations of hydrocarbons. Their optical parts cannot work well with condensing organic and inorganic matter.
- Gas Chromatographs
Though they are the most expensive hydrocarbon analyzers, gas chromatographs are very accurate. Gas chromatographs come handy in contexts that require advanced hydrocarbon detection. They offer a higher level of detail and specificity than other sensors.
- Catalytic Sensors
Catalytic sensors are the most attractive and least expensive hydrocarbon analyzers. Though they are easy to operate and maintain, they are less useful in ppm VOC monitoring. Their chemical and physical properties make them ideal for observing the flammable range concentrations of hydrocarbons and other flammable gases. However, they cannot respond to the low range concentrations of flammable gases such as hydrocarbons.
- Flame Ionization Sensors
Flame ionization sensors are the most economical, efficient and effective tools for hydrocarbon monitoring. They can work in industrial settings and provide better accuracy levels than catalytic sensors. They also require less maintenance than gas chromatographs. Flame ionization sensors are suitable for hydrocarbon monitoring in the parts-per-million range.
A good hydrocarbon should come with features that meet all federal and state requirements. The hydrocarbon monitoring system should include fault relays and alarms to provide warnings when the emission levels are higher than normal. It should also be accessible from remote locations and provide accurate readings that are convertible to weight statements. The hydrocarbon analyzer should also have a linear response to hydrocarbons.
