定义
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.
工作原理
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.

常见问题

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.
