The PSD-UV series of instruments have been engineered to assist you in cleaning samples such as AFM probes and surface. Each model operates using a high output ultraviolet (UV) light emitting grid (mercury vapor) that excites organic molecules and produces highly reactive ozone gas from oxygen that is present within the cleaning chamber. The system can be used with ambient air or with an external oxygen supply provided by the end user. The reactive ozone interacts at the molecular level with surface contaminants causing them to degrade. This method is particularly effective with organic contaminants that are frequently found on AFM probes and surfaces. The exact exposure times and methods required to remove various contaminants will, of course, vary and should be determined empirically.
