The replacement septa, ferrules, and other accessories you choose for your HPLC or GC can impact the quality of the system’s output.
Contamination from GC septa, for example, can be a persistent source of data biasing.
The cliche is true. You get what you pay for.
The GC septa from Hamilton below have an average life of about 100 injections.
The GC septa from SGE are the purest on the market - producing an average of 4x fewer contaminant peaks than low cost brands and about 20% fewer peaks than alternative high performance brands (based on 3rd party testing).
