Abstract
A method and system for spectroscopically determining surface and product characteristics is employed for rapid detection of product characteristics and/or the presence or absence of suspected analytes, and the concentration of the analyte. The method and system uses a signal wide band detector that does not require focusing optics in many environments. It can be used for cleaning validation of pharmaceutical products and process equipment.
