What do these products do in this instrument?
Filters: method-permitted sample-gas protection
Reduce particle or droplet load at method-permitted protection locations, consistent with the target gas and pretreatment architecture. Confirm filter media and construction for actual gas conditions, including added pressure drop and composition changes.
Filters provide method-permitted particle retention or component protection. Target components, pore size and filter material guide selection. Assess pressure drop, adsorption and recovery after replacement in the actual path.
Tubing and fittings: separate gas and liquid branch connections
Connect the main sample-gas path, condensate path and absorbent-liquid path separately, marking pressures and destinations. Check materials, vacuum sealing and recovery after maintenance separately. Condensate must not feed serially into the sample-gas analysis interface.
Tubing and fittings together form sealed connections and the actual transfer path. Check formulation, inner/outer diameters, length, tube-end positioning and port geometry, including added volume in residue and arrival delay.
Identify gas and liquid branches separately
List the main gas path, condensate drain and absorbent-liquid path separately. Record medium, vacuum or pressure, connection volume and destination for each section. Assess materials and sealing under actual media and maintenance conditions. Liquid-connection validation does not establish sample-gas suitability.
Validate filtration protection and target-gas composition together
Compare particle or droplet protection where the method permits, checking gas tightness, actual flow, added pressure drop and target composition. Condensation or adsorption can alter measured components. Confirm filter material and structure for sample-gas conditions; existing liquid-filter models cannot be assumed suitable.

Filtration protection in sample-gas branches
Filter materials may retain particles but also affect sample-gas composition. Include protection location, added pressure drop and analyte changes in method verification.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Filtration protection in sample-gas branches | Measure gas tightness, system flow and pressure drop. Compare target-gas composition before and after protection and check recovery after maintenance. | Adsorption, condensation, leakage or filter blockage can change sample-gas composition and flow. |
Check actual drainage/aspiration, gas tightness and effects on sample-gas composition. Validate recovery after maintenance.
Can a liquid filter be used directly for sample-gas protection?
Check filter material and structure against actual gas, humidity, temperature, vacuum and analytical targets. Validate gas tightness, pressure drop and composition changes. Confirm the specific configuration for the project.
Liquid flow, unloaded gas flow and gas-liquid drainage capability are not interchangeable. An absorbent-liquid pump is not necessarily suitable as a sample-gas pump.
