56 TRACE 1600/1610 Hardware Manual
a. Connect the power cable to the AC Input connector on the back of the GC and to
the wall outlet.
b. Flip up the power switch (breaker) to the position I.
5. Setup the GC.
a. Set the oven and injector temperature to 50 °C.
b. Use the column-flowmeter connector to verify that there is flow through the column.
If you do not have a flowmeter, dip the column outlet in a small vial of methanol.
Bubbles indicate there is flow through the column. If there is no flow, check that the
carrier gas is on, the GC inlet is pressurized, and the column is not plugged. If there is
still no flow, consult the section Analytical Troubleshooting in the TRACE
1600/1610 User Guide, or contact the Technical Support.
c. Allow the column to purge for few minutes.
6. Perform a column leak check.
a. Carefully push the capillary column end into the column section of the
column-flowmeter connector. See
Figure 58. Using a Flowmeter for Leak Check
A
b. If your GC is equipped with the touch screen as user interface, select the Leak Check
icon in the Maintenance menu, otherwise perform the Leak Check through the
Chromatography Data System by selecting the proper function.
c. Start the leak check to begin operation. The split and purge valves of the selected
channel are automatically closed and the channel is pressurized with carrier gas to the
leak check setpoint.
d. The system monitors the pressure for one minute. If the pressure does not drop more
than the maximum allowed sensitivity value, then the leak check will pass.
e. If the leak check did not pass, you should use the leak detector to find and fix the
leaks.
Tip Leaks can be caused by not tightening the fitting on the column-flowmeter
connector. We recommend that you check that fitting before looking elsewhere.
f. Repeat the leak check until no leaks are indicated.
