Quantum EELS – Gatan

Applications:   Elemental analysis using points, line profiles or maps at atomic scale resolution

The GIF Quantum® series represents Gatan’s 4th and most advanced generation of post-column energy filters. Redesigned from the ground up, the GIF Quantum® combines advanced dodecapole-based electron optics with a blazing fast CCD camera system to yield an imaging filter that defines the new state-of-the-art in the capture of both highly detailed EELS and EFTEM data sets with maximum throughput.

GIF Quantum™


Advanced options such as a 1 µs electrostatic shutter, a 10x faster camera, a 2 keV fast spectrum offset module, and DualEELS™ hardware and software, allow each Quantum model to be tailored to the applications at hand.
