Baseline signal issues on FID detector

Issue

Very high signal on FID detector

Environment

  • Gas Chromatography
  • TRACE 13X0
  • FID module

Resolution

  • 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 issues due to the use of gas generators and on-line purifying filters.
  • Check for FID gas flow issues.
  • Check for FID module issues. 
  • Check for TRACE 13X0 electronics module issues.
