Parallel EELS PEELS

The density inside the dilatation bands was measured using electron energy loss spectroscopy (EELS) with a Gatan 666 parallel EELS (PEELS), which was attached to the TEM. An accelerating voltage of 100 kV was used. The density of the dilatation band was calculated using the following equation (22) ... 

A Parallel EELS (PEELS) analysis of coke on ferrierite platelets was used by de Jong et aP to verify that the amorphous layer observed on the borders of the crystals was effectively amorphous carbon. 

An electron spectrometer is placed below the standard column in a TEM or STEM for EELS. In TEM, a defining aperture or slit selects the region contributing to the spectrum, while in STEM the probe naturally controls the area being analyzed. A ID electron detector can collect the EELS data from a point, and a 2D detector can collect data from a line. These techniques are sometimes called PEELS, for parallel...
