EXPEC-2000 Series Methane/NMHC/THC Analyzer

EXPEC-2000 Series Methane/NMHC/THC Analyzer

Product overview

Methane (CH4) is a colorless and odorless gas that plays a significant role as the primary component of natural gas. It exists naturally underground and beneath the ocean floor, as well as in the Earth’s atmosphere at levels of around 1,800 parts per billion (ppb). Human activities, including industrial processes, contribute to the emission of methane into the atmosphere when it is not properly managed or combusted. As a potent greenhouse gas with the ability to persist in the atmosphere, monitoring and reducing methane emissions are essential for environmental protection.The 28th Conference of the Parties to the United Nations Framework Convention on Climate Change（COP28）in 2023 prioritized ‘methane emissions reduction’ as one of its important targets.

Principle
FPI utilizes GC-FID method (direct test), through low-temperature enrichment-high temperature heat tracing, two-channel connected hydrogen flame ionization detector (FID) technology. The valve body switches back and forth to collect the sample into the quantitative ring. The total hydrocarbon in the empty column and the methane in the chromatographic column can quickly pass through the detector. The valve body makes the carrier gas flow reversely through the chromatographic column to blow the non-methane total hydrocarbon out of the analysis system without being detected.

Key features

• Measurement components include methane(CH₄), non-methane total hydrocarbon(NMHC), and total hydrocarbon(THC)
• Adopt heat tracing method, no residue left of high concentration samples, and comes with the advantage of accu-rate measurement data reliability.
• The high-temperature heat tracing technology developed for high boiling
  non-methane total hydrocarbon significantly reduces the chromatographic
  peak broadening of high boiling non-methane total hydrocarbons and
  allows the instrument to accurately measure the non-methane total hydrocarbons of high boiling substances amount
• Because the content of non-methane total hydrocarbon is calculated by the
  difference between total hydrocarbon and methane content, which significantly shortens the analysis cycle, analysis cycle less than 1.5 minutes operation continuously with free maintenance

Applications

• Greenhouse gas detection
• Petrochemical and chemical industry park plant boundary atmospheric monitoring
• Ambient air monitoring
