The JPS-9200 acquires wide photoelectron images from areas 10 mm x 10 mm or larger (maximum 18 mm x 50 mm). The surface (10 mm dia.) of SUS303, polished and cleaned with an organic solvent, was analyzed in the JPS-9200.The polished surface of the sample lost its wetness to a degree. Spot analysis at 50 um dia. and photoelectron imaging of an area of 10 mm x 10 mm were performed to identify the cause of the reduced wetness.
