Restek’s experience with surface coatings began in 1987. A client contacted us to pacify the metal surfaces of
their new explosives detector because we were known in the analytical industry as the silicone coating experts.
It “could not be done” according to the literature—but we developed technology to coat intricate metal parts
with an inert layer, preventing low ppt levels of explosives from adsorbing to the metal surface. Driven by this
success, we applied our
technology to capillary gas
chromatography columns,
essentially duplicating the
inertness of glass within metal tubing. Our highly robust stainless steel columns were perfect for process analyses.
The end product from this work was Silcosteel
®
treatment for stainless steel tubing. Silcosteel
®
treated tubing
currently is used in analytical testing apparatus made by all major manufacturers of gas chromatography
sampling and analysis equipment.
It “could not be done” according to the literature, but we did it.
