Electron spectroscopic imaging (ESI) is a short term for electron energy loss spectroscopic imaging. ESI is to date the most sensitive electron microscopic analytical technique and has a spatial resolution of 0.5 nm and a mass resolution of less than 50 atoms. ESI takes advantage of filtered, inelastically scattered, transmitted electrons to form(More)
Scanning electron microscopy (SEM) was used to study the surface ultrastructure of adult worms of Gongylonema pulchrum. The anterior end in both sexes was covered by numerous cuticular platelets. There was a pair of lateral cervical papillac. The buccal opening was small and extended in the dorsoventral direction. Around the mouth a cuticular elevation(More)
