4.3Capillary Analysis Using the Dual FID
(When a makeup gas flow controller is used)
To perform capillary analysis using a unit with the dual FID, makeup gas needs to be
supplied to the FID that a column is connected to.
In order to supply makeup gas, the optional makeup gas flow controller (P/N 221-70877-91:
1 flow path, 221-70877-92: 2 flow paths) are used.
Prior to installing a column, install the detector adapter (P/N 221-33193-91) to the detector's
joint.
Although an adapter and column are connected to the right (R) side of the dual FID in the
figure below, they can be connected to either side (L/R).
