ABSTRACT:
A process for preventing contamination of a reagent system by a reagent delivery system. The process is suitable for performing an iron determination of a sample which prevents iron contamination of the sample from metal or iron-containing surfaces contained within the apparatus used to perform the iron assay. The process comprises pretreatment of the reagent delivery system surfaces with a silane solution and then washing the pretreated surfaces with water to remove any excess silane solution. Generally, the silane solution is an organosilane solution which can be an emulsion.
