Yes. The Soft-Guard™ septa and caps will outperform most septa and caps on the market when used with most LCMS applications due to the inherent purity of the silicone rubber, the manufacturing technology and the cast PTFE.
For highly sensitive LC-MS and MS applications, we recommend our ultra-pure, colorless AQR™ brand septa and caps—engineered specifically for the most demanding chromatographic workflows. These caps also feature our advanced Soft-Guard™ technology, ensuring optimal performance and sample integrity.
