Enfinium™ EELS Spectrometers
Enfinium™ER (Model 977)
The Enfinium™ER EELS spectrometer applies the advanced features of the GIF Quantum®ER to our dedicated EELS product line.
The Enfinium™ER is a high performance EELS system incorporating the advanced features of the GIF Quantum®ER system in a dedicated spectroscopy system. The high spectral resolution of the Enfinium™ER is well matched to both Schottky and cold-FEG microscopes while the microsecond shutter and highspeed detector take full advantage of the high beam current of Cs corrected STEM systems. The 2.5 mm and 5 mm spectroscopy apertures of the Enfinium™ER EELS system support the high collection angles required for atomic column resolution EELS analysis, and the 1000 spectra per second, high-speed EELS acquisition mode means you can make use of every electron that hits the sample. A 500 x 500 EELS spectrum image can be acquired in less than 5 minutes!
The Model 977 Enfinium™ER Spectrometer can be upgraded with DualEELS™, high-speed 2 kV VSM and Gatan’s spectrum imaging packages. An integrated STEM detector is recommended if the Model 977 Enfinium™ER spectrometer will be used substantially for STEM EELS data acquisition to ensure high fidelity STEM signals at the collection angles recommended for EELS analysis. The Enfinium™ER is currently supported by Gatan Microscopy Suite® (GMS) 2 running under Windows 7 32-bit; optional 64-bit support is available and is recommended for most Spectrum Imaging applications.
