Troubleshooting and Maintenance Guide

Sample Decomposition in Inlet/Missing Peaks

•

Lower the inlet temperature.

•

Check for air or water in the carrier gas; verify gas purity
and functionality of traps.

•

Verify that the liner is appropriate for the sample being run.

•

Perform complete inlet maintenance: Replace all
consumable parts and bake out the inlet.

•

Install a deactivated liner.

•

Check for leaks at the septum, liner, and column fittings.
(See

“Checking for Leaks”

on page 99.)

•

Install an Agilent Direct Connect liner.

•

Use a pulsed pressure method for quicker sample transfer to
column.

•

Bake out the inlet.
