Abstract: An analytical system and method periodically monitoring an injection water distribution pipeline for the presence and concentration of formaldehyde or other aldehyde-functional biocide includes pumps, one of which provides a predetermined volume of injection water drawn from the pipeline at a sampling point and the other a predetermined volume of a reagent, preferably a buffered solution of dimedone, from a reagent storage vessel which are mixed and then heated in a chamber to a predetermined temperature to promote formation of any reaction products. The heated reaction mixture is passed to a detection cell and exposed to light of predetermined wavelength which, in accordance with the Hantzsch reaction, molecules having an aldehyde functional group that reacted with dimedone produce a fluorescence-emitting reaction product, the intensity of which is measured and compared to data previously obtained from standard aldehyde-containing solutions.

Abstract: Methods and systems for generating inspection results for a specimen with an adaptive nuisance filter are provided. One method includes selecting a portion of events detected during inspection of a specimen having values for at least one feature of the events that are closer to at least one value of at least one parameter of the nuisance filter than the values for at least one feature of another portion of the events. The method also includes acquiring output of an output acquisition subsystem for the sample of events, classifying the events in the sample based on the acquired output, and determining if one or more parameters of the nuisance filter should be modified based on results of the classifying. The nuisance filter or the modified nuisance filter can then be applied to results of the inspection of the specimen to generate final inspection results for the specimen.

Abstract: An object carrier, a system and a method is disclosed for the back light inspection of transparent or semitransparent objects. The carrier has a carrier base layer with photo luminescent properties which carries the transparent or semitransparent object on top of the layer. The transparent or semitransparent object could be a wafer and the object carrier could be a wafer chuck. At least one light source being arranged above the object carrier such that excitation light emitted from the at least one light source is directed through the transparent or semitransparent object to the layer with photo luminescent properties. The light returned from the layer with photo luminescent properties is collected by an objective and registered by a sensor.

Abstract: To facilitate setting of a parameter at the time of generating an inspection image from an image acquired by using a photometric stereo principle. A photometric processing part generates an inspection image based on a plurality of luminance images acquired by a camera. A display control part and a display part switch and display the luminance image and the inspection image, or simultaneously display these images. An inspection tool setting part adjusts a control parameter of the camera and a control parameter of an illumination apparatus. Further, when the control parameter is adjusted, the display control part updates the image being displayed on the display part to an image where the control parameter after the change has been reflected.
