Guard Column for Dual Column GC Analyses
This part is required for setup of dual column GC analyses (e.g. residual solvents by HS-GC-FID or pesticides by GC-ECD). Install one end of a ~ 25cm piece of this guard column into your GC inlet. Install the other end into the MXT-Y Splitter, which splits your injected sample into two separate columns for dual column analysis. Replace endcaps on remaining guard prior to storage.
