The cleanliness of parts is critical to many high technology industries, and impacts the viability of their products. Residual or introduced surface contaminants can dramatically alter the performance characteristics of critical components. These industries generally use multistep cleaning processes prior to assembly to assure the quality of their products.

Process optimization often means solvent extraction of the part followed by analysis of the extract. This reveals the identity and quantity of the bulk contaminants without revealing the location of those contaminants on the part.

In this poster note, learn how desorption electrospray ionization (DESI) imaging and high resolution mass spectrometry (HRMS) offer a route to the visualization, identification and quantification of contaminants on the surface that may be used to optimize an industrial cleaning process.
