Another advantage of ASEM is that we can visualize the cell
we want to analyze in the scanning electron microscope.
This visual inspection allows us to determine the quality
of the cells and any contamination and malformations.
The intracellular mineral
ion concentrations can be
quantified from the x-ray fluorescent spectrum. Each
element that we look at has a unique energy fluorescent
excitation or peak.
We express these units or
peaks in the spectrum generated
by the Electron Microscope analysis as EXA units. This is
called an EXA Test, EXA stands for Energy Dispersive
X-ray Analysis. It also stands for Elemental X-Ray
Thus EXA Test®
