JMDMT #2540 Microfossils of Cyanobacteria in Carbonaceous Meteorites

The James M. DuPont Meteorite Collection - Pressure Scanning Electron Microscope: The Hitachi S-3700N VP instrument has a Tungsten emitter electron gun and is capable of magnifications in the range of 5X to 300,000X. It has both Secondary (SED) and Backscattered Electron Detectors (BSED). This instrument is equipped with a 4 Pi EDS system with a Silicon Drifted Silicon Detector capable of operating for Z%3EBoron. FE1 Quanta 600 (FESEM and ESEM): The FEI Quanta 600 Field Emission Gun Scanning Electron Microscope is an extremely flexible instrument that has both low- and ESEM vacuum capability. Consequently it is capable of charge- free imaging and analysis of both non-conductive
