Are the Soft-Guard™ Septa and caps compatible with LCMS or LCMS/MS?

Yes. The Soft-Guard™ Septa will outperform most septa and caps on the market when used with most LCMS applications.

For very sensitive LCMS/MS applications we recommend our Advanced Quality, AQR™ septa and caps which is colorless, ultra-pure and designed for the most critical chromatography applications. The AQR™ cap incorporates all the benefits of the Soft-Guard technology as well.
