GC-PrevuePlus vs Alternatives: Feature Comparison

Troubleshooting Common GC-PrevuePlus Issues and Fixes

1. Software won’t start

• Cause: Corrupted installation or missing dependencies.
• Fix: Reinstall GC-PrevuePlus (run installer as admin). Ensure required runtime libraries (e.g., Microsoft Visual C++ Redistributable) are installed. Restart system.

2. Instrument not detected

• Cause: USB/serial cable issues, wrong COM port, driver problem.
• Fix: Check physical connections, replace cable if faulty. In Device Manager confirm driver appears and note COM port. In GC-PrevuePlus select correct COM/USB port and baud rate. Reinstall instrument drivers.

3. Data acquisition fails or aborts mid-run

• Cause: Buffer overflow, unstable connection, incompatible firmware.
• Fix: Reduce data logging rate or sample size. Update instrument firmware to supported version. Move logging to local drive with sufficient space. Use a dedicated PC for acquisition.

4. Chromatogram shows noise or unstable baseline

• Cause: Column contamination, carrier gas impurities, detector instability.
• Fix: Bake out or replace column; install/replace gas purifier; check detector settings (temperature, flow). Verify consistent carrier gas pressure.

5. Peaks mis-integrated or missing

• Cause: Incorrect integration parameters or noisy baseline.
• Fix: Adjust integration thresholds, smoothing, and baseline correction in the software. Manually re-integrate critical peaks. Use higher signal-to-noise acquisition settings.

6. Wrong retention times between runs

• Cause: Temperature program drift, flow instability, leaks.
• Fix: Verify oven temperature program and calibration. Check for leaks (use leak detector). Ensure carrier gas flow is stable and set correctly.

7. Exported data unreadable or corrupted

• Cause: Incorrect export format or permissions error.
• Fix: Export in common formats (CSV, NetCDF) and verify encoding. Run GC-PrevuePlus as admin if permissions block file writing. Reopen exported file in compatible software.

8. Licensing or activation errors

• Cause: License file missing/invalid or system clock mismatch.
• Fix: Confirm license file is in the correct folder and valid for this PC. Sync system clock with internet time. Contact vendor for license reissue if needed.

9. Slow performance or UI lag

• Cause: Insufficient PC resources or background processes.
• Fix: Close other applications, increase RAM/SSD if possible. Ensure antivirus isn’t scanning active data folders; add exclusions for GC-PrevuePlus data directories.

10. Unexpected crashes or error codes

• Cause: Software bugs, corrupted files, or incompatible OS updates.
• Fix: Note exact error code/message. Check GC-PrevuePlus logs and Windows Event Viewer. Update to latest software patch. If persistent, reinstall and restore settings from backup.

Quick checklist before calling support

1. Note software version, instrument firmware, OS version.
2. Reproduce issue and capture screenshots/logs.
3. Confirm cables, power, and gas supplies.
4. Try restart, reinstall, and update steps above.
