This study compares the surface inertness of 2 coatings on the inner walls of 1/8” stainless steel tubing: SilcoNert®2000 (SilcoTek®Corporation) and Silonite (Entech Instruments Inc.). The data show significant differences in surface inertness of the two coatings.
Test results of 8 common active compounds show the SilcoNert 2000 treated tube is the superior surface for analytical and process sampling. The Silonite surface is drastically more active; exhibiting significant surface activity with very poor resolution of active compounds. For a mildly active compound such as 4-chlorophenol, the SilcoNert 2000 surface showed nearly 6.7 times better response than the Silonite surface. For a more active compound such as 1,6-hexanediol, the SilcoNert 2000 column surface showed a response nearly equal to the response seen on the analytical column alone. With high activity compounds the Silonite column system showed total adsorption of 1,6-hexanediol.
