Siltek Deactivation

Siltek® is the most chemically inert surface by Restek. It is prepared through the same process as Sulfinert® treatment, and pricing is equal, but, for emphasis, we use the Sulfinert® name to describe 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.

Inertization types

Actually there exist 6 passivation techiques based on inertization of metaly surface by fused silica:

• Silcosteel®
• Siltek™
• Sulfinert®
• Silcosteel®-AC
• Silcosteel®-CR
• Silcosteel®-UHV

FocusLiner

The FocusLiner™ is the first liner in the world to secure quartz wool by means of a tapering above and below the wool. This ensures the wool remains in the correct position to wipe the needle tip during injection. Reproducibility is greatly improved with chromatographers reporting Relative Standard Deviations (RSD's) of between 0.3 and 0.7%.

The new Fast FocusLiner™ has a narrow ID (<2.5 mm) making it ideal to be used with Fast Capillary Columns (0.1 mm ID).

Main features

• All liners deactivated with high temperature deactivation
• Innovative designs
• Excellent reproducibility, precision, accuracy and reliability
• Simple to use
• Maximum sensitivity / detection levels
• Guaranteed to fit
• Guaranteed premium inertness

Immuniafinity column materials

Mycotoxins are toxic substances naturally produced by molds (fungi) that may contaminate agricultural commodities by growing on grain or feed. These molds result in a variety of dangerous mycotoxins, such as aflatoxin, fumonisin, deoxynivalenol (DON), ochratoxin, and zearalenone - some of which are known human carcinogens. The U.S. Food & Drug Administration (FDA) has determined acceptable levels of certain mycotoxins for consumption by humans and different species of animals. Furthermore, the European Union (EU) continues to tighten its regulations. This stiffening of EU import standards drives worldwide adoption of mycotoxin tests that are ever more precise, accurate, and sensitive.

One method of mycotoxin analysis includes sample extraction and clean-up with VICAM immunoaffinity columns, followed by high pressure liquid chromatography (HPLC). In addition to HPLC analysis, VICAM immunoaffinity columns can be used for the quantitative detection of mycotoxin present through the use of a fluorometer. The use of VICAM immunoaffinity columns with the aforementioned instruments can provide a reading of actual mycotoxin content over a range of contamination levels.

More information about products are available in the product catalogue. List of Official methods using Vicam immunoaffinity columns is available here.
