Agilent Inlet Septa

Inlet Septa

◈ Product Information
One of the key components of sample introduction is the inlet septum. All columns must have sufficient carrier gas head pressure to establish flow through the column. Septa maintain the leak-free seal and exclude air from the inlet. They come in different sizes and are made from different types of materials specific to inlet type and analysis needs. Septa are available for a variety of different applications and have different upper temperature limits. Lower temperature septa are usually softer, seal better, and can withstand more punctures (injections) than their high-temperature counterparts. If septa are used above their recommended temperatures, however, they can leak or decompose. This causes sample losses, lower column flow, decreased column life and ghosting.
