chelating agent
Pronunciation: KEE-lay-ting
A chemical compound that binds to metal ions, preventing mineral deposits and corrosion on surgical instruments during cleaning.
Full Definition
Chelating agents are specialized cleaning additives that form stable complexes with metal ions, particularly calcium and magnesium found in hard water, preventing them from interfering with the cleaning process or causing mineral deposits on instrument surfaces. In surgical instrument reprocessing, chelating agents help maintain instrument integrity, prevent spotting and staining, and enhance the effectiveness of detergents by neutralizing water hardness. Common chelating agents include EDTA (ethylenediaminetetraacetic acid) and phosphonates.
Usage
Usage note: Often abbreviated as 'chelant' in technical documentation.
