Non methane total hydrocarbon analyzer

Model 3010Non methane total hydrocarbon analyzerThe use of a heated hydrogen flame ionization detector is a classic method for measuring volatile organic compounds (THC, VOC, TOC, NMHC). The advantage of this method is that it can accurately measure hot/wet gas samples, and the entire sampling and analysis process is maintained at a high temperature (191 ℃), which can effectively prevent the loss of hydrocarbons caused by the condensation of high molecular weight hydrocarbons in the injection pipeline.

Model 3010Non methane total hydrocarbon analyzerIt is an instrument for measuring the total concentration of volatile organic compounds, with a wide range of applications, such as boiler flue gas detection, incinerator flue gas detection, and volatile organic solvent leakage detection. 3010 HFID has a good correlation with lipids, alcohols, esters, ketones, and aromatic compounds, and is a reliable classic method for detecting total carbon and hydrogen concentrations.

System Characteristics

The instrument uses the High Temperature Hydrogen Flame Ionization (HFID) method to detect the sample gas. To minimize the impact of sample gas condensation on measurement accuracy, the instrument samples at a high temperature of 191 ℃ throughout the entire process. At the same time, a compensating air bypass system is used to prevent sample gas condensation at the back pressure regulator.

Model 3010 features an ignition/shutdown optimization scheme design, where the flame ignites and the sample gas is introduced when the combustion measurement chamber and heating pipeline reach temperatures above 130 ℃. Shutdown: As soon as the FID flame is extinguished or the fuel source is turned off, the built-in sensor will immediately shut off the corresponding electromagnetic control valve.

Built in heated catalytic air purifier and zero point gas automatic generator can provide zero point gas and organic free combustion air for the instrument, avoiding the problems of cumbersome operation and high subsequent use costs caused by wearing an additional bottle of zero point gas or auxiliary gas for the instrument.

Fuel gas and standard gas are consumables. To ensure convenient use of the instrument in the later stage, the gas cylinder used is a domestically standardized gas cylinder that can be filled and flushed by any gas distribution company in China

Operation

In practical applications where oxygen content is unpredictable, we recommend using a hydrogen/helium mixture as fuel to reduce the impact of oxygen synergy. In environments with stable oxygen content, Model 3010 can also choose hydrogen as fuel.

The instrument operation mode is simple, and people who have not been exposed to the instrument can operate it after simple training.

option

Signal computer version/mobile APP software/printer, etc. can be used for data collection, data monitoring, historical data verification, and providing detection reports.

The host, in conjunction with a methane cutter, can measure NMHC and perform conversion measurements of total hydrocarbons/CH4/non methane total hydrocarbons

Measuring principle

It is a flame generated by the combustion of hydrogen and air as energy source. When organic compounds enter the flame generated by the combustion of hydrogen and oxygen, chemical ionization occurs at high temperatures, producing ions several orders of magnitude higher than the base flow. Under the directional action of a high-voltage electric field, an ion flow is formed. The weak ion flow is amplified by high resistance to obtain an electrical signal proportional to the amount of organic compounds entering the flame, and the organic matter is quantitatively analyzed based on the size of the signal.
