Locate the source, drive and receiving position for this task
Required inputs are wash formulation, volume/time, spray/aspiration geometry, air/foam and waste capacity. Confirm liquid contact, pressure and destination along each illustrated section before defining drive and connection responsibilities.
Coordinate formulation, coverage and contact time
Select the wash liquid and process for the target contamination, and calculate installed delivery and available time. Increasing flow may shorten contact or increase accumulation; coordinate it with wash-station geometry and waste removal.
| Condition to compare | Information required | Selection affected |
|---|---|---|
| Contamination location | Probe interior, exterior, seat or shared segment | Define washing coverage and paths |
| Washing conditions | Formulation, inflow volume and contact time | Compare the available window and wash-liquid compatibility |
| Drainage conditions | Wash-station peak inflow and permissible accumulation | Prevent waste from contacting cleaned surfaces again |
Compare product options against task requirements
The following candidate options match this page's responsibilities. Compare them against the operating conditions described, then check capacity, materials and interfaces on the product pages. Card images show representative configurations; suitability must still be confirmed at actual operating points and by application results.
| Product category | Corresponding role | Confirm before selection |
|---|---|---|
| Custom wash probe | Washing interface for probe interiors/exteriors or containers | Confirm contaminated surfaces, coverage, aspiration height and peak waste removal |
| DPL30 liquid diaphragm pump | Liquid supply or auxiliary circulation | Select by installed resistance, actual wash or working fluid and task window |
| DPGL800 gas–liquid diaphragm pump | Suitable gas–liquid aspiration or container-vacuum branches | Confirm inlet medium and waste architecture; not for continuous liquid-only transfer (100% liquid) |
Prevent wash-station residue from reaching the next sample
Complete the specified internal and external washing, preventing residual wash-station liquid from contacting the next sample. After maintenance, check spray position, probe condition and drainage before resuming detection.
Action records should link commands, valve or interface states and actual received results. When raw material, container or sample identity changes, reconfirm shared paths and conditions permitting the next step. Completion of drive movement alone does not replace task acceptance.
Check recovery using blanks after concentrated samples
Evaluate high-to-low concentration changes and blank recovery, diagnosing shared-volume residue, surface adsorption and waste accumulation separately. A clean appearance does not establish acceptable analytical carryover.
| Validation scenario | Measurement or observation | Interpretation and action |
|---|---|---|
| Recovery from residue | Follow a high-concentration sample with a low sample or blank | Locate the contaminated surface before adjusting the program |
| Idle periods and liquid changes | Recheck the first wash cycle and effective supply | Increased pump flow does not replace corrected chemistry or coverage |
Record test medium, configuration, installed path and operating sequence; present routine operating points and boundary results separately. Calculations support design discussions, component documentation checks models, and installed measurements confirm the actual task.
After an abnormality or maintenance, first identify which segment needs recovery
Insufficient supply, foam, air aspiration and a full waste vessel can disrupt the wash cycle. Stop supply and resolve waste-removal faults, then check the complete cycle after recovery.
Retain current source, container identity, completed actions, valve or interface state and actual receiving information. Use the table to locate the stage that changed before deciding to retry, continue or restart. After recovery, recheck the relevant operating point before returning an uncertain action to the automatic cycle.
