acts as an accelerator the invention having been described the following examples are presented to illustrate rather than to limit the scope of the invention examples 1 through 3 illustrate the modifiers and methods for characterizing the effectiveness of the modifiers according to the present invention adsorbent solutions were prepared by mixing or dissolving a test compound or u201c adsorbent u201d in hplc grade ethanol available from aldrich chemical company inc of milwaukee wis table 1 summarizes the five adsorbent solutions used in this example the five adsorbent solutions included one control solution of ethanol two solutions each containing a known modifier and two solutions each containing a previously unknown modifier the two known modifiers are fumaric acid and tolyltriazole the tolyltriazole tt100 is a mixture of 4 and 5 methyl isomers of methylbenzotriazole and is available from pmc specialties group inc of westlake ohio the two previously unknown modifiers are pre hydrolyzed organo silane mixtures available from dow corning of midland mich the solution designated z6020p in table 1 is a 50 50 5 solution of z6020 pre hydrolyzed organo silane methanol and water respectively z6020 is a diaminofunctional silane n beta aminoethyl gamma aminopropyltrimethoxysilane normally used as a coupling agent the solution designated z6030p in table 1 is a 50 50 5 1 solution of z6030 pre hydrolyzed organo silane.
