In the Check Leak press line, set the pressure at which the leak check will be performed. The value must be between 10 and 999 kPa (1.45 and 145 psi) and must be less than the carrier gas pressure coming into the GC. f. In the Sensitivity line, set the maximum pressure drop that is allowed during the test. The value must be between 1 and 10 kPa (0.145 and 1.45 psi). A typical value is 5kPa. g. Press CLEAR to exit the Leak Check Settings menu and return to the previous menu. L. COL. LEAK CHECK Start leak check Leak Check settings h. Select Start leak check to begin operation.

CHECKING L COLUMN Pressure (200) Elapsed time 0.90 Use to abort Note To abort a leak check, you can press STOP. i. 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. R/L.LEAK CHECK COMPLETED SUCCESSFULLY Leak check passed. 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. 6 ISQ User Guide Thermo Scientific
j. Repeat the leak check until no leaks are indicated. 16. Calibrate the carrier gas flow. 1 Changing the Column Replacing the Factory-Installed Column a. Carefully push the capillary column end into the flow meter section of the column flowmeter connector, as shown below. Figure 4. Column Flowmeter Connector CAUTION - INSTRUMENT DAMAGE: Do not allow the column flowmeter connector to exceed 80 °C. Otherwise, it will melt and damage the instrument. b. Connect the flowmeter to the dedicated fitting on the column flow meter connector. c. Press Column Eval to open the following menu: COLUMN INFORMATION Right column Left column < Note The available options (Right column or Left column) will differ depending on the configuration of your GC. If you have a FOCUS GC, you do not need to select an option. Note Make sure the Vacuum Compensation parameter is set to OFF in the Carrier menu. Otherwise an accurate column evaluation cannot be performed. Thermo Scientific ISQ User Guide 7
