Flexotherm™ Heated Sample Lines are used in laboratories and industrial settings to transport gas samples from a collection point to an analyzer without altering the sample’s composition. Preventing condensation is the most critical reason for using them, as any phase change in the sample would lead to inaccurate measurements.

Standardizing temperature: Some regulatory and testing standards require a minimum sample line temperature (e.g., 191°C for specific EPA methods) to prevent the loss of semi-volatile organic compounds.

Improving response time: A dry, uncontaminated sample path allows for faster transport times and more stable, reliable analyzer readings.

Preventing freezing: In cold environments, heated lines prevent moisture from freezing and blocking the sample line.

Ensuring representativeness: By maintaining a sample’s temperature and composition, a heated line ensures that the gas analyzed is a true representation of the gas at the collection source.
