A septum in liquid chromatography acts as a barrier between your sample vial and the outside environment, while also allowing a needle to pierce and enter the vial without any added considerations. This way sample extraction can be achieved as you pave a path toward MS adoption. Plus, this septum actively prevents leaching and sticking.
The septum forms a barrier between your sample analyte in the vial and the outside atmosphere. This barrier protects your sample from external contamination while allowing a needle (from a manual or automatic syringe) to enter the vial, and extract the sample for the next stage of separation.

When selecting a vial, cap and septum to contain analytical solutions, there are several factors to take into account. In most analyses, the cleanliness of the vial and the septum are most important. 1,2 With analyses where multiple injections of the same analyte (s) are performed over time, the ability of the septum to reseal is a consideration.
