The TCD-to-FID Series Connector connects output flow from a Thermal Conductivity Detector (TCD) to the column inlet of a Flame Ionization Detector (FID) to perform a second analysis of the same injected sample.
This document provides instructions for installing the TCD-to-FID Series Connector (Accessory G4319A) on an Agilent 6820 Gas Chromatograph. The connector allows the output flow from a Thermal Conductivity Detector (TCD) to be directed to the column inlet of a Flame Ionization Detector (FID), enabling a second analysis of the same injected sample.
It connects output flow from a Thermal Conductivity Detector (TCD) to the column inlet of a Flame Ionization Detector (FID) to perform a second analysis of the same injected sample.
Both a TCD and an FID are required. If an ECD is present or in a dual detector situation, the unneeded detector must be removed.
Required tools include electrostatic protection (grounded wrist strap), a T-20 Torx screwdriver, and a 7/16-inch wrench.
