Data mapping services in the field of chemical membrane separation processes featuring high resolution mapped data images of inorganic chemical elements showing membrane contaminate color coded information about each individual element utilizing scanning electron microscope and energy dispersive x-ray spectrometry detector. The resulting data maps can help identify specific deposits and distinguish them from precipitated scales based on their chemical make-up and morphology. Organic deposits cannot be characterized using this method, however, their presence can be verified under certain circumstances by the presence of carbon
