Agilent Technologies 8697 Headspace Sampler
Agilent Technologies · Model 8697 Headspace Sampler
GC touch screen and browser interface shows headspace status, guides, and tracking Accommodates 48 vials on two removable racks or 120 vials on 5 removable racks (XL tray) Isolated carrier flow path as in the 7697A headspace sampler to safely vent your vials Improved transfer line with a captive septum retainer nut and improved inlet bracket for a more secure connection Optimized sample overlap lets you simultaneously heat and shake up to 12 vials Supports 10-mL, 20-mL, or 22-mL vials with no limitations on running mixed vial sizes Removable sample racks and smart park allow trays to be exchanged while the headspace sampler is operating so you can add samples as the sequence is running Optional cooling plate for the 8697-XL tray can chill sensitive samples to 4 °C Optional barcode reader for streamlined sample tracking Smart park button and tray rack LEDs show the status of the headspace sampler Transfer line interface (XLSI) accessory allows a headspace sampler and ALS to connect to the same inlet on the GC.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Vial leak detected
HighSymptoms: "Vial leak detected" during pressurisation, sequence pauses or skips the vial.
Root cause: Poor vial crimp/seal, wrong cap, or a worn sampling-probe septum / seal.
Transfer-line or flow-path leak
HighSymptoms: System leak-check diagnostic fails, poor sensitivity or carryover.
Root cause: Loose transfer-line septum retainer nut, a bad ferrule, or a leak at the inlet bracket.
Vial not picked up / wrong vial size
MediumSymptoms: Gripper misses a vial or reports the wrong size, sequence action triggers.
Root cause: Tray or rack mis-seated, gripper misalignment, or a wrong vial size loaded.
Oven / loop not reaching temperature
MediumSymptoms: Not-ready state, poor reproducibility, temperature fault.
Root cause: Oven heater, sample-loop heater, or a temperature-sensor fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Vial leak detected
- Confirm correct vial size, cap and a firm crimp.
- Inspect and replace the sampling-probe septum / seal.
- Re-run a known-good vial to confirm.
- Run the system leak-check diagnostic for the full flow path.
- Re-tighten the transfer-line retainer nut and re-test.
Symptom: Flow-path leak / poor sensitivity
- Run the built-in system leak-check diagnostics.
- Check the transfer-line septum retainer nut and the inlet bracket connection.
- Replace ferrules at any leaking union.
- Confirm carrier flow and pressures via the browser interface.
- Re-run a standard to confirm recovery.
