Graphite 52M – VOC Gas Analyzer

The Graphite 52M is a VOC (Volatile Organic Compounds) gas analyzer utilizing FID (Flame Ionization Detection) technology. It is one of the few devices certified with QAL 1 (EN 15267-3, EN 14181).

1. FunctionContinuous measurement of total hydrocarbons (THC), non-methane hydrocarbons (nmHC), and methane (CH4). Available in two versions:
   • Graphite 52M-S: Measures THC only.
   • Graphite 52M-D: Simultaneously measures THC, nmHC, and CH4.
2. Measurement Range: From 0-10 ppm to 0-30,000 ppm (depending on configuration).
3. Key Feature:
   • Sample gas contact components are heated and maintained at 191°C to prevent condensation, ideal for measuring heavy hydrocarbons.
   • Certified by TÜV and MCERTs, compliant with European standards (EN 12619, EN 13526) and U.S. standards (US EPA CFR 40-1065).
   • Available in a portable version for flexible on-site use.
4. Application:
   • Monitoring VOC emissions from mitigation equipment (e.g., thermal oxidizers or catalytic systems).
   • Assessing environmental compliance and performance of emission treatment systems (carbon adsorption, catalytic converters, scrubbers).
