Vernier Mini GC Plus (GC2-MINI)

Specifications and User Guide

• If you have the Go Direct Mini GC, see Go Direct Mini GC Troubleshooting and FAQs
• If you have the original Mini GC, see Mini Gas Chromatograph Troubleshooting and FAQs

Troubleshooting

• Inconsistent Flow
  ⚬ Likely Cause: Worn or damaged septum.
  ⚬ Solution: Replace the septum.
• Inconsistent Peak Areas
  ⚬ Likely Cause: Irregular injection volume or worn septum.
  ⚬ Solution: Check your injection technique and replace the septum.
• No Communication
  ⚬ Likely Cause: Software mismatch or cable/Bluetooth connection.
  ⚬ Solution: Verify software versions and check USB cables.
• No Power
  ⚬ Likely Cause: Power cord or switch issue.
  ⚬ Solution: Confirm that power plugs are fully inserted and the switch is turned on.

General Use Tips

• Use Approved Compounds Only: Always refer to the list of acceptable compounds in the user guide before injecting new samples.
• Avoid High-Water Samples: You CANNOT inject samples that contain more than 5% water. This will ruin the detector.
• Hamilton Syringe Note: The syringe shipped with the device has a brown bumper on the needle. Do not remove this bumper—it protects the injection port.
