Code 6006 Unexpected module behavior.

The ion trap voltage is too low. Liquid may be present in the ion trap. The voltage may have been shorted due to detector flooding.

The detector gas flow and the drain pump are automatically turned on and the pump flow is stopped.

To resolve the problem:

Make sure that the gas flow and drain pump are turned on. Check that liquid flows out of the waste line. Keep in mind that liquid may not be seen leaving the detector for certain mobile phases with high volatility or with low flow rates. Resolve the flooding.

See Resolving Flooding In the Detector.

Code 6007 Gas flow too low.

The gas flow ratio is below the specified range for more than 60 seconds.

The detector gas flow and the pump flow are automatically stopped. The drain pump remains turned on for a short period longer and is then turned off.

To resolve the problem:

  • Make sure that gas is still supplied to the detector. Check that the gas supply pressure is within the allowed range. Observe the gas specifications for the detector.

  • Check that the nebulizer pressure is set as specified on the nebulizer gas pressure certificate.

  • Turn the detector off and on. Check the self-test results.

  • Check the Gas Flow Ratio. The value should be within the allowed range.

If the message persists, contact Technical Support.

Code 6008 Module malfunction detected.

The detector gas flow and the pump flow are automatically stopped. The drain pump remains turned on for a short period longer and is then turned off. Turn the detector off and on. If the message appears again, contact Technical Support.

Code 6009 Nebulizer gas pressure too low.

The nebulizer gas pressure has dropped below the minimum limit.

The detector gas flow and the pump flow are automatically stopped. The drain pump remains turned on for a short period longer and is then turned off.

  • Make sure that gas is still supplied to the detector. Check that the gas supply pressure is within the allowed range. Observe the gas specifications for the detector.

  • Check that the nebulizer gas pressure is set as specified on the nebulizer gas pressure certificate.

  • Check the gas inlet tubing and gas filter assembly for signs of gas leakage and proper connection to the detector. Turn on gas flow and check for any unusual noise.

  • Turn the detector off and on. Check the self-test results.

  • Turn the gas flow off and on to check that the internal gas solenoid valve functions properly.

If the message persists, contact Technical Support.

Code 6010 Nebulizer gas pressure too high.

The nebulizer gas pressure has exceeded the maximum limit.

The detector gas flow and the pump flow are automatically stopped. The drain pump remains turned on for a short period longer and is then turned off.

To resolve the problem:

  • Make sure that gas is still supplied to the detector. Check that the gas supply pressure is within the allowed range. Observe the gas specifications for the detector.

  • If the gas supply pressure exceeds 620 kPa (6.2 bar, 90 psi), the overpressure relief valve will open. This creates a loud hissing sound. To remedy the gas supply overpressure, see Resolving Gas Supply Overpressure.

  • Check that the nebulizer gas pressure is set as specified on the nebulizer gas pressure certificate.

  • Check the gas inlet tubing and gas filter assembly for proper connection to the detector.

  • Turn the detector off and on. Check the self-test results.
