LeaK CheCK

After everything is installed, but before running a sample, you

will need to run a Leak Check on your system.

1. After starting Versa TekLink™2G, initiate the automatic

leak checking sequence from the main screen by clicking

on the Leak Check icon in the icon toolbar, or by going to

tools | Leak Check.

2. After making the leak check selection, the unit will go from

System Ready to Leak Check. The Leak Check procedure is an

interactive process requiring the user to insert a fresh, tightly

capped headspace vial into position 1 of the carousel.

• User prompts and leak check results are updated in the

pop-up dialog boxes. The user will be required to monitor

the dialog boxes for direction and guidance through the

leak check procedure. The leak check results are recorded

in the sample history log for future reference.

• If the system fails the leak check, the user will need to

isolate the system leak and correct the problem. This is

important in order for the system to run under optimal

conditions, as well as to maintain leak tight conditions

within the GC injection port.

items to Check for Leaks

1. Check the connection at the GC injection port.

2. Check the Valco fittings around the 6-port sample valve.
