Abstract:

Efforts were concerned with improvemen s for a mass spectrograph to permit accurate analysis of olid mat rials. Met ods were discussed for improving spark yield, working sensitivity, ease of operation a d analytical accuracy. Improv ment in average ion yield and in ease of sp rk anipula io as achieved. Photographic emulsion variations were a serious limitation to sensitivity and to analysis accuracy but with a satisfactory plat , e sitivi y of appro i a ely 1 in 10 to the 9t power was obtained with exposure durations of about 1 12 hours. The flexibility of Knudsen Cell operation was greatly enhanced by a complete redesign of the supporting structure. Author
