19. If left alone, you must be in a crib, a highchair, a playpen or secured in some way

EDS or EDX; is a chemical microanalysis technique used in conjunction with scanning electron microscopy (SEM). 

FIGURE 1

The EDS technique detects x-rays emitted from the sample during bombardment by an electron beam to characterize the elemental composition of the analyzed volume. 

Features or phases as small as 1 µm or less can be analyzed.

When the sample is bombarded by the SEM's electron beam, electrons are ejected from the atoms comprising the sample's surface. 

The resulting electron vacancies are filled by electrons from a higher state, and an x-ray is emitted to balance the energy difference between the two electrons' states. 

The x-ray energy is characteristic of the element from which it was emitted.

The EDS x-ray detector measures the relative abundance of emitted x-rays versus their energy. 

The detector is typically a lithium-drifted silicon, solid-state device. 

When an incident x-ray strikes the detector, it creates a charge pulse that is proportional to the energy of the x-ray. 

The charge pulse is converted to a voltage pulse (which remains proportional to the x-ray energy) by a charge-sensitive preamplifier. 

The signal is then sent to a multichannel analyzer where the pulses are sorted by voltage. 

The energy, as determined from the voltage measurement, for each incident x-ray is sent to a computer for display and further data evaluation. 

The spectrum of x-ray energy versus counts is evaluated to determine the elemental composition of the sampled volume.
