Where tip-based environmental sample aliquoting and transfer occur
This task covers disposable-tip air displacement in environmental sample preparation. The pump drives liquid in the tip while the platform coordinates source, receiver and consumable motions. Check pickup sealing, actual liquid and sample identity before setting aspiration, dispensing and motion programs.
Record the original vessel, preservation state and destination. Particle-containing samples may differ when aliquoted at different times; include mixing and transfer order in the program.
Product responsibilities in this operation
The air-displacement pump drives liquid inside the tip; the platform manages tips, wells and movement. Associate liquid destinations and consumable states with every operation.
For this environmental sample preparation task, confirm disposable-tip specifications and pickup sealing, actual liquid type, remaining source volume, immersion depth, working volume and receiving location.
Organize the sequence by actual architecture
- For this disposable-tip transfer, verify original sample source, collection time, preservation condition and receiver. Complete any method-required mixing.
- Confirm tip suitability for the actual matrix and particles, then check pickup sealing, aspiration position and aliquoting order.
- Deliver the sample into the designated receiving vessel and record actual volume and identity. Assess the complete transfer using aliquot representativeness, analyte recovery and contamination blanks.
Define operating conditions for this task
| To define | Details |
|---|---|
| Actual operating conditions | Disposable-tip specification and pickup seal, actual liquid class, source volume remaining, immersion depth, working volume and receiving position |
| Acceptance target | Measure actual receipt at the target vessel, including low source levels, tip pickup and ejection, and contamination across sample sequences. Verify sample or well identity and downstream method results. |
| Fault localization | Tip leaks, aspiration of air, hanging droplets, incorrect immersion or missed tip changes can affect delivery and contamination. |

Validate operation results at the receiver
Measure actual volume received in the target vessel, covering low remaining volume, tip pickup/disposal and contamination across sample sequences. Verify sample or well identity and subsequent method results.
Evaluate blanks, recovery, aliquot representativeness and restart according to the method.
Locate abnormalities and restore the next operation
Tip air leaks, air aspiration, retained droplets, incorrect immersion or missed tip changes can affect delivery and contamination status.
Check the volume already delivered and the destination vessel first. Handle the tip and affected sample according to the experimental procedure, then verify readiness before the next action.
Dilution metering can share general engineering methods, but field preservation, particles and analyte loss require separate checks.
