Component Specifications

Definition
An internal conduit or liner is a tubular component installed within sampling probes to create a protected pathway for fluid samples. It prevents contamination, reduces sample degradation, and maintains sample integrity by isolating the fluid from the probe's outer structure. This component is critical in applications requiring precise chemical analysis, quality control, or process monitoring.
Working Principle
The internal conduit/liner operates by providing a smooth, inert surface through which fluid samples flow from the sampling point to the collection or analysis system. It minimizes turbulence, prevents adsorption of sample constituents onto probe materials, and protects against external contaminants. In some designs, it may be replaceable to maintain cleanliness and performance.
Materials
Typically made from chemically inert materials such as PTFE (Teflon), PFA, FEP, stainless steel (e.g., 316L), or specialized polymers. Material selection depends on compatibility with sampled fluids (e.g., corrosive chemicals, high temperatures) and required flexibility or rigidity.
Technical Parameters
  • Length Customizable to probe design
  • Inner Diameter 3-10 mm
  • Surface Finish Smooth, non-stick
  • Pressure Rating Up to 10 bar
  • Temperature Range -50°C to 260°C (depending on material)
Standards
ISO 15848, DIN 11866
