GCOM-3220 volatile organic compound online analyzer Introduction: The GCOM-3220 volatile organic compounds online analyzer uses a dedicated chromatographic column combination, gas path backflushing technology, and dual hydrogen flame ionization detector (FID) technology to achieve simultaneous detection of non methane total hydrocarbons+benzene series (8 components) or non methane total hydrocarbons+some characteristic VOCs components using a dual FID detector. It is suitable for high temperature, high humidity, and high dust conditions, and the data can be uploaded to the corresponding monitoring platform according to requirements. Application fields: petrochemical, organic chemical, surface spraying, printing and packaging, coatings and packaging, electronics industry, furniture manufacturing, shipbuilding industry, automotive manufacturing, and other fields. Features: 1. Dual FIDs independently detect non methane total hydrocarbons and benzene derivatives; 2. MFC electronic flow control; 3. Dual chromatographic column analysis gas circuit backflushing design, with low interference in continuous sample measurement; 4. Multi range automatic switching, supporting centralized detection of inlet/outlet samples; 5. Gas path and flame status, cycle monitoring diagnosis, and safety control. Technical parameters: Principle：GC-FID Temp stability of column box：≤0.5% Measuring range：NMHC: 0~1000μmol/mol (customizable) Measurement period：NMHC≤2mi BTEX≤6min Baseline noise：≤0.5pA Dimension(W×H×D)：482×221×559 (mm) (W×H×D) Baseline drift：≤5pA (30min) Display：Touch screen Qualitative repeatability：RSD7≤1.0% Communication output：10/100M ethernet port, RS232 Quantitative repeatability：RSD7≤2.0% Communication protocol：Modbus-RTU, Hj212 or local protocol Span drift:≤3.0% (4h) Power：220±22VAC, 50±1Hz, 900W LOD：NMHC (measure in carbon)≤0.05ppm Linearity：R≥0.99 LOD：≤0.1ppm (measure in benzene) Temp accuracy of column box：±0.1℃
