Sampling Probes: Liquid-Sample Source Interfaces
In probe-based configurations, withdraw liquid from sample vessels in coordination with motion, metering and rinsing. Check tip materials, low source volumes and switching residue alongside complete analytical blanks.
Custom sampling probes connect source containers to receiving positions. Diameter, tip, surface and interface depend on sample and container. Tip geometry must work with metering drive and motion sequences.
Match component geometry to actual containers
Sampling probes must fit container openings, bottoms, minimum levels and motion strokes. Record actual contact surfaces and permitted positions before defining tips, interfaces and motion space; appearance alone is insufficient.
Evaluate interfaces by receiving or cleaning results
At the source, check reachable positions and low remaining volume; at the receiver, check actual volume, droplets or permitted residue. Test wetted-surface maintenance and recovery for the next container during consecutive operation. Reconfirm position and delivery after changing probes, tubing length or containers.

| Condition | To confirm |
|---|---|
| Container and position | Provide opening, bottom, minimum level, positioning error and available motion space. |
| Liquid contact and surfaces | Specify sample or reagent, residue requirements and internal/external probe cleaning. |
| Actual function | Check delivery, coverage, residue, solid-phase retention or mixing results according to the task. |
| Operation | Specific operating conditions |
|---|---|
| Discrete liquid-sample transfer and introduction conditions | Actual sample volume, remaining source volume, probe-tip height, aspiration/dispensing speed and system liquid |

Discrete liquid-sample transfer and introduction conditions
Delivery to a dilution vessel primarily requires volume control; delivery to an introduction interface also requires system-specific continuous flow, pulsation and pressure checks. Evaluate materials and sample-change recovery using the actual matrix.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Discrete liquid-sample transfer and introduction conditions | Measure actual delivery at the receiver, covering routine small volumes and maximum task volume, first dose after idle, sample changes and high/low concentration sequences | Air aspiration, clots/particles, probe contact with a wall or leakage alter actual delivery |
Check concentration ratios, mixing, blank recovery and method results. Evaluate preparation and sample supply separately.
Can sampling and wash probes be replaced based on similar appearance alone?
Confirm tip, channels, interfaces and operating positions separately, then validate each probe's aspiration/dispensing or cleaning results. Similar appearance does not imply equal wetted volume, coverage or residual-liquid levels.
A sample-preparation pump is not automatically suitable for nebulizer supply. Confirm the introduction system for the specific instrument.
