    摘要: Apparatus and method for determination of the endpoint of a cleaning process in which cleaning fluid is contacted with a structure to effect cleaning thereof. The cleaning process includes contacting a cleaning fluid with a structure to be cleaned and producing a cleaning effluent having a sensible heat thermal energy characteristic corresponding to extent of cleaning of the structure, disposing an object in the cleaning effluent that interacts with the cleaning effluent to produce a response indicative of the sensible heat thermal energy characteristic of the cleaning effluent, and monitoring such response to determine when the cleaning is completed. An endpointing algorithm and endpoint monitoring are also described, as well as endpoint monitor sensor elements that are useful to determine endpoint conditions in an efficient and reproduceable manner.
