- Abstract
The studies detailed in this paper were concerned with the 2009 Centre for Applied Science and Technology (CAST) black iron (II/III) oxide powder suspension formulation, which is currently recommended for operational use in the United Kingdom for the visualization of fingermarks on nonporous surfaces. These studies included component comparisons and shelf-life trials and have demonstrated: The impor tance of the iron (II/III) oxide product, because not all iron oxide powders on the market with CAS number 1317-61-9 can be used to produce effective powder suspensions. That the Triton X-100-ethylene glycol surfactant solution (2009 CAST formulation) is effective when used in place of a proprietary Kodak Photo-Flo (cat number 501 0640) based surfactant solution (2006 CAST formulation). That the Triton X-100 - ethylene glycol surfactant solution (stock detergent solution) remains effective after storage for at least two years. That fully mixed iron (II/III) oxide powder suspension (2009 CAST formulation) showed no appreciable decline in effectiveness after storage for 100 days (approximately).
