What do these products do in this instrument?
Tubing and fittings: connecting sample matrices to instrument interfaces
Build the actual path traversed by samples, standards and blanks. Check materials for acid/salt matrices and pressure locations. Coordinate tubing length, shared volume and installed signal arrival with the method.
Tubing and fittings together form sealed connections and the actual transfer path. Check formulation, inner/outer diameters, length, tube-end positioning and port geometry, including added volume in residue and arrival delay.
Design tubing and fittings as a complete wetted path
Tubing, fittings and ports jointly determine sealing, transfer volume and medium-contact coverage. Materials and dimensions must suit formulation, operating conditions and installation. Include tubing length and interface volume in priming, shared residue and arrival delay. After connection changes, recheck delivery and cleaning through the actual path.
Calculate connection volume and post-maintenance recovery
Shared volume affects liquid arrival and flushing; interface gaps may retain the previous composition. Record length, actual bore and tube insertion position. After disassembly, reprime and check seals, then compare first-cycle delivery, blanks or recovered product to confirm path recovery.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Materials and assembly | Provide formulation, tubing inner/outer diameters, length, fitting structure and port fit. |
| Volume and load | Calculate shared and replacement-component added volumes; measure actual flow and response. |
| Maintenance recovery | Record disassembly locations and added volume; recheck priming, sealing and first-cycle received results. |
| 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 |

| Product | Configuration option | Conditions to verify |
|---|---|---|
| Tubing materials and dimensions | Connection paths and shared volume | Bore, length, load and actual formulation jointly determine materials and dimensions |
| Rigid-tubing fittings | Tube-end positioning and sealed connections | Check tube outer diameter, threads, seal structure and port-bottom geometry |
Related operations and architecture comparisons
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.
Does a fitting that tightens prove the tubing assembly is suitable?
Also confirm port geometry, tube-end positioning and seal fit. Check leakage, hold-up and performance after repeated maintenance under actual conditions; thread engagement alone is insufficient.
A sample-preparation pump is not automatically suitable for nebulizer supply. Confirm the introduction system for the specific instrument.
