The injection point septum is a part of the machine that has the potential to wear. This port only lasts 100-200 injections. The injection port temperature,which is selected by the analyst,may be high or low causing a shortened septum life span,decreased sensitivity,poor separation of liquid material,or decomposition of the sample.
