Component Specifications

Definition
A precision-engineered component designed for automated sample acquisition in analytical instrumentation, featuring controlled fluid dynamics, contamination prevention mechanisms, and compatibility with various sample matrices. It serves as the primary interface between the sample source and the analytical system, ensuring representative sampling while maintaining system integrity.
Working Principle
Operates through pneumatic or mechanical actuation to extend into the sample medium, create a pressure differential for fluid aspiration, and retract while maintaining a sealed pathway to prevent contamination. Incorporates flow control mechanisms and self-cleaning features to ensure consistent sample delivery.
Materials
316L stainless steel (primary wetted parts), PTFE/PEEK fluid pathways, ceramic tips for abrasive resistance, FDA/USP Class VI compliant elastomers
Technical Parameters
  • Length 150-600 mm
  • Diameter 3-10 mm
  • Flow Rate 0.1-10 mL/min
  • Surface Finish Ra ≤ 0.8 μm
  • Connection Type 1/4-28 UNF or metric equivalents
  • Pressure Rating 0-100 psi
  • Temperature Range -20°C to 150°C
Standards
ISO 8655, DIN 12880, ASME BPE

Frequently Asked Questions

What maintenance is required for inlet probes?

Regular cleaning with compatible solvents, inspection for wear/damage, replacement of seals annually, and calibration verification every 6 months or 10,000 cycles.

Can inlet probes handle viscous or abrasive samples?

Yes, with appropriate material selection (ceramic tips for abrasives, larger diameters for viscous fluids) and modified flow parameters.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
