2 Before Use
2.1Setting Analytical Flow Lines
GC-2014 does not operate normally without setting analytical flow lines. Always set
analytical flow lines before using the unit. Refer to “Chapter 3. Installing Packed Columns
and Setting Analytical Flow Lines” and “Chapter 4. Installing Capillary Columns and Setting
Analytical Flow Lines” for detailed descriptions.
Setting analytical flow lines creates the following benefits during operation.
1. Conditions of analytical parameters for
each line can be set and monitored.
For example, when the [SET] key of
the gas chromatograph is pressed,
temperatures of columns, injection
ports, and detectors as well as carrier
gas flow rate can be set and monitored
on a single screen.
2. A protective mechanism operates to
foster more stable operation conditions.
For example, when a carrier gas
cylinder becomes empty while TCD is
used, the flow controller detects an
error and automatically lowers the
column temperature and stops
conduction to the TCD filament in order
to prevent damage to the column and
TCD filament.
