Abstract
The construction and operation of a surface contaminant detector are described. The sensitivity of the solid‐phase bonding of gold‐to‐gold to adsorbed organic matter is used in this instrument to indicate the contamination level in the environment or on the surfaces of metallic solids. The detection range appears to be unlimited. The behavior of the instrument under various conditions is described for over l05 tests with the same pair of gold contacts. Some of the applications for the portable detector are the testing of clean benches, clean rooms, storage containers, and the surfaces of metallic parts.Keywords
