What to do if I have poor sensitivity with Inficon Micro GC Fusion 2-Module Measuring Instruments?
- KKyle 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.
