    What to do if I have poor sensitivity with Inficon Micro GC Fusion 2-Module Measuring Instruments?
    • K
      Kyle StokesAug 20, 2025
      Poor sensitivity in your Inficon Measuring Instruments, leading to reduced peak area counts, can stem from several factors. First, ensure your Sample Pump Time is adequate; increase it to at least 15 seconds, or even 30-60 seconds if ample sample is available. Also, increase the Inject (ms) time. Contamination could be the cause, so perform a bakeout to clean the columns. Give the instrument at least 3 minutes to warm up. Check for external leaks using a leak detector and tighten any loose fittings. Make sure the carrier gas inlet pressure is within 400-427 kPa (58-62 psi). Finally, ensure your carrier gas purity is between 99.995% and 99.9995%, adding traps or filters as needed, or replace the cylinder.

    What to do if calibration is poor on Inficon Micro GC Fusion 2-Module Measuring Instruments?
    • D
      David PetersonAug 22, 2025
      If you're experiencing poor calibration with your Inficon Measuring Instruments, resulting in unexpected concentration amounts, several factors could be at play. First, ensure the carrier gas purity is between 99.995% and 99.9995%, adding hydrocarbon/moisture/oxygen traps or particulate filters to improve purity. Also, ensure there are no contaminants and an adequate supply of calibration gas. Try restarting the Micro GC Fusion. Check for external leaks in the carrier and calibration gas lines, tightening all fittings. Ensure all peaks of interest are identified and fully integrated. Finally, increase the Backflush Time until all peaks of interest appear on the chromatogram, if applicable.

    Why is my Inficon Measuring Instruments chromatogram a flat line?
    • C
      Christopher JohnsonAug 25, 2025
      A flat line chromatogram with no peaks on your Inficon Measuring Instruments can occur if the Inject (ms) time is set to 0 ms; change it to a non-zero value. Also, ensure the Sample Pump Time is set to at least 15 seconds. If these steps don't resolve the issue, there may be a malfunction in the column or injector, sample pump, or detector.

    What to do if I have inverted peaks on Inficon Micro GC Fusion 2-Module Measuring Instruments?
    • A
      Amber JacksonAug 26, 2025
      Inverted peaks or broad humps in your Inficon Measuring Instruments chromatogram may be due to several reasons. First, check the carrier gases to ensure they are correctly connected to the appropriate inlet and properly configured in the user interface, and check for leaks. Ensure the carrier gas purity is between 99.995% and 99.9995%, using traps or filters if needed, or replace the cylinder. If broad, sporadic peaks appear, extend the Hold Time or increase the Column Temperature to address carryover from a late-eluting compound. Also, clean or replace the sampling device or filter if they're contaminated.

    What to do if I have poor separation on Inficon Micro GC Fusion 2-Module Measuring Instruments?
    • R
      ronnie62Aug 28, 2025
      Poor separation in your Inficon Measuring Instruments, leading to co-elution of compounds, can be due to contamination; conduct a bakeout to clean the columns. Optimize the Column Temperature and Column Pressure method parameters by reducing them to improve separation. If problems persist, there may be a malfunction in the detector or column.

    How to fix air peak on blank injection with Inficon Measuring Instruments?
    • K
      Karen TurnerAug 30, 2025
      An air peak appearing on a blank injection with your Inficon Measuring Instruments could indicate that the column head pressure method parameter is set too low; verify it's above 15 psi, as insufficient pressure may prevent the inject valve from sealing fully. Also, verify sufficient carrier gas pressure from the cylinder, ensuring the inlet pressure is between 400-427 kPa (58-62 psi).

    What to do if GC will not power on (Inficon Measuring Instruments)?
    • V
      vbryantSep 1, 2025
      If your Inficon Measuring Instruments GC won't power on, the power supply might be damaged, consider replacing it. Also, replace the fuse on the back of the 4-module Micro GC Fusion.

    What to do if Inficon Micro GC Fusion 2-Module Measuring Instruments user interface front page cannot be accessed?
    • S
      Sharon TapiaSep 3, 2025
      If you cannot access the user interface front page of your Inficon Measuring Instruments, ensure there is a connection to the computer LAN by verifying the ethernet cable is plugged in, replacing it if necessary, and checking the LAN port functionality. If using a static IP address, verify that the computer and Micro GC Fusion IP addresses have been set correctly. If using wireless, verify that the device is connected to the Micro GC Fusion wireless connection. Verify the Micro GC Fusion IP address by looking at the front panel display. Verify that the web browser meets the required specifications. Restart Micro GC Fusion.

    What to do if a peak is missing on Inficon Measuring Instruments?
    • R
      Robert HowardSep 5, 2025
      If a peak is missing on your Inficon Measuring Instruments, and backflush is applicable, increase the Backflush Time method parameter until all peaks of interest appear on the chromatogram.

    What to do if a peak is saturated on Inficon Measuring Instruments?
    • D
      Dawn LawsonSep 6, 2025
      If a peak is saturated on your Inficon Measuring Instruments, shorten the Inject (ms) time. Also, lower the Injector Temperature.
