I'd like to know your best practise for your liner replacement on Agilent 6890N GC. We're analysing Denatured Fuel Ethanol, and we are doing a liner replacement every 3 months. We then have a rince sequence that will do a triplicate injections of a sample of denatured ethanol to saturate the liner.

Routine GC maintenance is important when doing gas chromatography, and replacing GC inlet liners is one of the most common tasks. In this example, we replace the liner in an Agilent 7890 gas chromatograph.
