Siltek® is our most chemically inert surface. It is prepared through the same process as Sulfinert®
treatment, and pricing is equal, but, for emphasis, we use the Sulfinert® name to describe our inert
surface specifically intended for sampling, storing, transferring, or analyzing parts-per-billion levels
of active sulfur compounds (e.g., hydrogen sulfide). One of the more popular applications for Siltek®
treatment is the passivation of inlet liners for gas chromatography, and the many GC applications performed
using Siltek®-treated liners are a testament to the inertness of this surface.
If you're storing, transferring, or analyzing parts-per-billion levels of active sulfur compounds, chlorinated
pesticides (especially endrin and/or 4,4’-DDT), semivolatile compounds, or other chemically active molecules,
we recommend you request Siltek® treatment for your glass, stainless steel, steel, or high performance
alloy system components.
Examples of Siltek®-treated systems and components include inlet seals for injection systems in gas
chromatographs, and inlet liners for GC analysis of chlorinated pesticides.
