Why GC septum installation matters

GC inlet septum correct selection, handling and installation are important to maintain optimal analytical performances.

The septum must be replaced regularly: optimised gentle septum piercing - featured by HTA autosamplers - is needed in modern high-throughput labs to increase the GC septum lifetime and consequently keep the instrumentation downtime for maintenance to a minimum.

Moreover, the septum replacement procedure represents a critical and error-prone phase: a loose septum nut can lead to carrier gas leaks and pressure fluctuations, while excess septum compression can cause a wide range of problems, from analytical issues due to increased septum coring/bleeding up to syringe needle damage.

That’s why HTA has recently introduced a dedicated test to check the correctness of GC septum compression after septum replacement.
