12.1Packed Column Injection Port (Dual INJ)
During analysis using packed columns, a sample is injected into an injection port and the entire
evaporated sample is injected to the columns. A mass flow controller is used to control the
column flow rate so gas is supplied at a specified flow rate even when the column flow path
resistance and temperature change.
The GC-2014 packed model has an injection port that two packed columns can be attached to
(dual INJ) as standard. An injection port that only one column is attached to (single INJ) is
available as an option. For the single INJ, refer to its instruction manual.
