Gold Star Mothers Stamp - Analysis Using Scanning Electron Microscopy and Mass Spectrometry
Introduction:
Since 1949, the JEOL legacy has been one of outstanding innovation in developing instruments used to advance scientific research and technology. JEOL has over 60 years of expertise in the field of electron microscopy, more than 50 years in mass spectrometry.
In this applications note, we performed an analysis of a Gold Star Mothers Postage Stamp by using three JEOL instruments. We used the JSM-IT300LV which the latest addition to JEOL‘s popular series of analytical low vacuum SEM, , the JMS-T100LP “AccuTOF- DART” the first commercially available ambient ionization mass spectrometer, and the JMS-S3000 “SpiralTOF” which has highest mass-resolution and mass accuracy of all commercially available MALDI-TOFMS systems. We can therefore correlate analyses from various analytical techniques on the same sample.
Experimental:
A Gold Star Mothers Stamp from 1948 has a lead chromate pigment that we analyzed via: the JSM-IT300LV with an EDS spectrometer, the JMS-T100LP “AccuTOF DART” and the JMS-S3000 “SpiralTOF”.
