For Agilent 8960 gas chromatograph with unstable carrier gas flow, common troubleshooting steps include:

1. Carrier gas purification check: Confirm whether the carrier gas is contaminated or the purification device fails; replace or regenerate the purification column if necessary.
2. Flow and pressure verification: Use a flowmeter or the instrument's built-in monitoring function to test the stability of carrier gas flow rate and pressure; adjust to the specified range if there are fluctuations.
3. Leak inspection: Check key connections (such as column joints, inlet septa, tubing interfaces) for leaks using leak detection agents or pressure decay methods; repair or replace faulty components promptly.
4. Supply system check: Ensure the gas cylinder has sufficient pressure and the regulator/flow controller works normally to avoid unstable supply caused by low gas pressure or faulty accessories.
