The GIF QuantumERS™ imaging filter represents the new standard in EELS and EFTEM instrumentation.  No other commercial system provides the level of EELS and EFTEM performance afforded by the QuantumERS™ imaging filter.  With its extreme spectral resolution and stability, it is the system of choice for high-resolution monochromated sources.  The GIF QuantumERS™ imaging filter includes all the features and advantages of the GIF QuantumER™ imaging filter with the added feature of enhanced stability electronics, hand-tuned and matched components, and extensive tuning, testing and qualification of all key systems. 

The GIF QuantumERS™ imaging filter is sold only for use with qualified monochromated TEMs; these system require extensive site selection and environmental testing.

Base Configuration


Hardware

The basic instrument consists of a GIF QuantumERS™ imaging filter with a 2kx2k CCD detector, an entrance flange, computer controlled BF/DF detector, pneumatic aperture assembly, magnetic prism, pre-slit quadrupole assembly, post slit multipole lens assembly, computer controlled slit, and all standard EELS/EFTEM software mentioned in the following paragraph. Where required, a high performance computer workstation is supplied (See Recommended Computer worksheet for details).  For full analytical STEM support, see the model 777 STEMPack product, which includes all the software and hardware required for STEM spectrum imaging.

 

Software

The GIF QuantumERS™ series imaging filters are supported via GMS 1.9, which is exclusive to the GIF Quantum™ series, and the new streamlined AutoFilter® for GMS 1.9 software interface.  GMS software licenses for GIF operation, system tuning, and EFTEM/EELS data acquisition and analysis are included with each GIF Quantum™ imaging filter purchase.  This includes drivers and basic GIF and camera operation software, AutoFilter tuning, EFTEM mapping and quantitative analysis of EELS spectra.  The GIF QuantumERS™ imaging filters comes standard with licenses for basic Gatan EFTEM spectrum image data acquisition and analysis.
