Built-in Back-Flush Procedure Automatic Ignition Vocs Equipment for Total Hydrocarbons and Auxiliary Environmental Parameters

The core monitoring targets include total hydrocarbons, methane, non-methane hydrocarbons (NMHC), and benzene series (BTEX). For specific industrial scenarios, we can also customise the system for other VOC characteristic factors.

The standard analysis cycle for methane and NMHC is no more than 2 minutes. For BTEX, the total analysis time is within 480 seconds. For other customised characteristic factors, the cycle can be adjusted according to customer requirements.

We employ a fully heat-traced sampling and transport line, maintaining a constant elevated temperature throughout the entire flow path. This eliminates any "cold spots" that could cause condensation and adsorption of high-boiling components, thereby preserving the representativeness and authenticity of the monitoring data.

The system incorporates an automatic backflush cleaning function that, after each analysis, reverses the flow to purge residual high-boiling substances from the column. This effectively protects column cleanliness, extends the service life of this critical component, and significantly reduces the cost of routine consumable replacement.

Multiple safety redundancies are in place. The FID detector can automatically re-ignite, and if a flame-out is detected, the system immediately shuts off the hydrogen supply to prevent leakage. Moreover, the unit has power-loss memory and auto-recovery -after power is restored, it restarts automatically without manual intervention.
