I am having problems recently when running assays with the GC. Two months ago, our assays were somehow almost the same with the suppliers certificate of analysis assay.  Lately, we are getting high assay; sometimes more than a hundred percent recovery of the assay.  We already bought standards from different suppliers and we are still getting high results.  We continually replace the glass liner after 100 injections together with the septum.

What detector are you using? Have you tried doing full maintenance (change septa, liner and cut column... possibly clean injection port)?
