Abstract
A method for the detection of tin is presented. A specimen is first contacted with a ruthenium-containing species to create a contacted region of the specimen. At least a portion of the contacted region is then irradiated by an excitation radiation and monitored for a relaxation radiation emitted in response to the excitation radiation.
Claims20
A method for detecting the presence of tin, comprising the steps of:
- (i) contacting a specimen with a ruthenium-containing species to create a contacted region of the specimen;
- (ii) irradiating at least a portion of the contacted region with an excitation radiation;
- and
- (iii) monitoring the contacted region for a relaxation radiation emitted in response to the excitation radiation.

A method for detecting the presence of tin on a surface of an article, comprising the steps of:
- applying an acidic solvating solution on the surface of the article, the solvating solution comprising a halide;
- applying a solution of ruthenium (III)-ligand complex on the surface to create a contacted region of the article;
- irradiating at least a portion of the contacted region with an excitation radiation comprising ultraviolet radiation, and
- monitoring the contacted region for a relaxation radiation emitted in response to the excitation radiation.
