This article is a troubleshooting guide for when the Flame Ionization Detector (FID) does not ignite or the flame keeps going out. Cause: If the FID is having ignition issues, it is due to the …

• The FID is a DESTRUCTIVE, mass sensing detector • Cations generated in the flame are counted and produce the detector signal • Analytes that have the greatest number of low …

A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography. The measurement of ions per unit …

Nov 10, 2022 · FID noise can result from many contributing factors, including: Contamination in the gas supplies to the GC (gas contamination usually yields a high background of >20 pA). …

Dec 20, 2022 · If the FID interconnect spring is bent, damaged or has bad contact with FID base, it can cause a short circuit in the FID signal circuitry. The consequence is an extremely high …

Jan 13, 2022 · Perform FID maintenance and replace the FID jet. If it ignites manually and the flame stays on with the normal FID gas flows, replace the igniter and re-test. If this fails, …

The 6890/6850 FID uses a hydrogen flame to burn organic samples, resulting in increased ionization that is measured as a current—values up to the 10^6 pa range. The GC will auto …

Jun 18, 2024 · This document describes how to troubleshoot a Trace 1300 / 1600 Series FID module.

The FID is a relatively simple detector in that if the electronics are functioning, a sudden change in performance is often either a matter of checking flows and cleaning or replacing the jet.

Jan 13, 2022 · Check for column bleeding issues by disconnecting the column and capping the FID. Check the collector signal cable of the FID. Check the gases purity and seek main line …
