TFS Quattro ESEM
Brief description:
Multi-purpose high-resolution environmental-SEM.
The Quattro S is a dedicated environmental SEM (ESEM), that is a suitable platform for in-situ observation of complex structured materials. This customized ESEM allows studies across a large range of pressures while on-line mass-spectroscopic analysis of the gas phase promotes the structure-reactivity correlation under relevant conditions. The versatility of this instrument is also noted in the study of oxidation, alloying, corrosion, etching, crystal growth and catalysis.
