SAFETY PRECAUTIONS
Use the following safety guidelines to help ensure personal safety and to help protect the detector
system from potential damage.
2.1
HIGH VOLTAGES
Exercise extreme caution where this label is found. High Voltage is present and can cause burn,
shock and/or cause serious injury.
There is circuitry in the detecting unit that generates high voltage (200 VDC) required to
bias the detector. Terminals carrying these voltages may be exposed when covers or panels are
removed.
2.2
□
□
□
□
2.3
ELECTRO STATIC DEVICE (ESD) WARNING
Use ESD handling precautions when handling the electronics. Static voltages as low as 60 volts
can destroy the state-of-the-art integrated circuits used in the system.
Always ground yourself to the equipment chassis before removing or replacing a printed circuit
board (PCB).
PCB repairs should always be performed on a conductive surface, with the technician grounded
(via a conductive wrist strap with a built in current limiting resistor) to this surface.
Use an antistatic bag when carrying PC boards.
NOT HOT SWAPPABLE
The electronics are NOT hot swappable unless otherwise specified. The power to the system must
be turned off before inserting or removing any of the modules, boards or any of the interconnecting
cables. If this precaution is not taken, component will be damaged nearest to the connecting pins.
2.4 COOLING
Detector cooling
The detecting unit is cooled by the detecting unit body’s heat sink fins. No fans are used, just
ambient cooling. Be sure the detector body is not blocked or covered. Keep away from heat radiators or
other heat sources.
Analyzer cooling
The analyzer is cooled by multiple fans inside the analyzer. Be sure the fan speeds are properly set
in the bios, and that the fans are all operational. The components inside the analyzer may fail if used
with inadequate air cooling. See Figure 7.
DPP Box cooling
The DPP Box has components which can get very hot. The box should be kept away from any heat
sources for adequate operation.

Safety Precautions
2.5
RADIATION SAFETY
The electron microscope generates ionizing radiation when the electron beam is energized. The
detector is designed to have radiation leakage far less than the allowable level when properly
mounted with all covers and shielding in place.
EDAX warrants that its detectors and microscope interfaces when assembled and installed per EDAX
Engineers or Representatives, will provide Radiation Safety performance levels that will be in
compliance with the original Microscope design specifications.
Removal of any of the system's covers must be done by qualified EDAX Factory trained service engineers
or representatives. Opening covers or bypassing interlocks may expose users to radiation.
If the EDAX detector is removed from the microscope, it should be replaced by the original blanking port
cover provided by the microscope vendor.
Modification of covers or shielding or use of any other material than provided by EDAX or the
microscope vendor must be reviewed by a certified radiation expert and EDAX Inc. before use.
Caution:
The radiation levels should be checked around the instrument after any service in
which covers or any radiation containment parts were removed.
2.6
EXTENDING DETECTOR WINDOW LIFE
Introduction
The detector is sealed with a very thin window to permit light element x-rays to easily pass through it.
When the window is damaged, this contaminates the atmosphere surrounding the X-ray detector which
in turn can degrade detector performance or cause detector failure. Damage to the window can be
caused by physical contact, excess vibration, exceeding pressure or temperature specifications, vapor
condensation, electrical discharge to the detector or other factors.
2.6.1
DO NOT ALLOW THE DETECTOR TO COME INTO CLOSE PROXIMITY OR CONTACT
WITH HIGH VOLTAGE COMPONENTS
Do not allow the detector to come into close proximity or contact with high voltage components inside the
electron microscope, e.g. the extraction grid of a video detector. This can lead to an unsafe electrical discharge to
the detector which may damage the window.
Element Basic User Guide

Safety Precautions
2.6.2 PREVENT PARTICLE CONTAMINATION INSIDE THE SAMPLE CHAMBER
Particulates inside the sample chamber have a tendency to become entrained in the gas flow while
venting the sample chamber. The gas flow during a chamber vent or increase in chamber pressure is
generally turbulent meaning that entrained particles can fly in all directions, including toward the
detector window. Particulates which impact the window can cause micro cracks compromising the
vacuum seal of the window. In more extreme situations, particles can fully penetrate the window
causing what is known as a “bullet hole”, which causes a larger leak in the detector. It is also possible to
dislodge particles from the sample via the electron beam. If these particles are charged, they may be
accelerated toward the detector, which is at ground potential.
Recommendations:
□ Always use particle free gloves when loading samples or working in the sample chamber.
□ Be certain that there are no loose particles on the sample before placing the sample in the
chamber. Sample surfaces, fractures and powdered samples stuck to an adhesive should be
cleaned with compressed air to ensure the surfaces are clean and free of loose particles.
□ Avoid venting the sample chamber too quickly. Specifically, do not exceed 10 cm/s gas velocity
into the chamber, as this can increase the risk of particle-induced detector window damage. This
may require a small aperture in the vent port or decrease in supply pressure if N2 purge is used
to reduce the gas velocity.
□ If there is a high risk of particulates becoming dislodged during some operation in the
microscope, fully retract the detector to minimize the risk of damaging the detector window.
2.6.3 PROPER CARE WHEN USING A COMPRESSED GAS TO VENT THE SAMPLE CHAMBER
Ensure that the gas pressure does not exceed 2 atm.
Recommendations:
□ Release any latching mechanism that is designed to keep the chamber door closed.
□ Make certain that the chamber door will open normally when the chamber reaches atmospheric
pressure.
□ Avoid venting the chamber too quickly as this can cause unsafe pressure-induced vibrations on
the window. See recommendations in section 2.6.2 above.
2.6.4
AVOID HITTING THE DETECTOR OR INDUCING MECHANICAL VIBRATIONS IN THE
DETECTOR OR WINDOW
The detector window can be ruptured by excessive physical vibration or shock.
Recommendations:
□ Be careful not to run samples into the EDS detector.
□ Close the sample chamber door gently.
□ Do not pull the sample chamber door open while venting the sample chamber. This may lead to
unsafe pressure fluctuations inside the sample chamber which could damage the detector
window.

Safety Precautions
2.6.5 AVOID TOUCHING THE WINDOW
Recommendations:
□ Exercise extreme caution when working near the detector window. The collimator provides a
physical barrier to protect the window. Do not work with tools near the window.
□ If it is necessary to remove the collimator, the collimator should be removed and installed by a
trained technician so as not to touch the window or stress the end cap tip.
□ Do not direct pressurized gas or liquid streams at the detector window, for example in an
attempt to clean the window.
□ If necessary to clean the microscope chamber, retract or remove the detector using extreme
caution not to bump the detector tip or collimator.
2.6.6
LEAVE THE SEM IN HIGH VACUUM MODE
When not in use, If possible, leave the SEM in High Vacuum mode instead of in low vacuum or wet mode.
2.6.7 DO NOT EXPOSE THE DETECTOR TO EXTREME TEMPERATURES
Be mindful of conditions which may cause vapor condensation on the window or may cause the
temperature at the window to exceed manufacturer’s specifications. This may occur during a
microscope chamber bake or operation of a heat stage.
Recommendations:
□ If there is a possibility that the sample may emit vapors while in the sample chamber, especially
vapors acidic or alkaline in nature, fully retract the EDS detector to minimize the risk of
condensation on the detector window.
□ Take care when using a heating stage to follow manufacturer’s guidelines. Prior to using the
heat stage, confirm the EDS detector window type and temperature specifications as well as the
heat load on the EDS window during operation of the heating stage.
2.6.8 DO NOT EXPOSE THE DETECTOR WINDOW TO PLASMA
We recommend you do not expose the detector window to a plasma generated by a plasma cleaner.

4.4 LIGHT ELEMENT OPERATION
1. Check that the geometry is correct when collecting spectra. For example, an incorrect tilt used,
giving an incorrect Take Off Angle, will affect the Quant results. You can also correct this after
the data has been collected by editing the spectra file parameters.
2. Check that you are using a well-defined peak when quantifying. Avoid using peaks that are
“buried” in the background.
3. Use one of the longer amp times when specifically looking for light energy elements. They
typically provide better light element performance.
4. Use low accelerating voltage when specifically looking for light energy elements.
3. Make sure the samples are flat and homogeneous when possible.
4. Collect for sufficient time to improve the statics when the peaks are very small, for example
when looking at Boron.
4.5 FREQUENTLY ASKED QUESTIONS (FAQ)
Q1. Should I leave the detector powered on all of the time?
A1. In most laboratory conditions (stable power, temperature controlled), leaving the detector powered
on all of the time is fine.
Q2. Should I leave the detector cold all of the time?
A2. The detector will reach operating temperature in about two minutes, so it does not need to be left
cooled when not in use. It is okay to leave the detector cold when the microscope chamber is left under
vacuum. There is a user preference option to automatically turn the cooling off after inactivity, in case
the user prefers to turn the cooling off automatically.
Q3. The software displays a message that the detector temperature is not changing, or a
communication problem with the detector. What should I do?
A3. In this case, power off the detector using the switch on the small black power “brick” for the
detector then reboot the PC. Then power the detector back on after Windows has started.
Q4. How often should I calibrate?
A4. Many labs only calibrate their systems during a regularly scheduled service preventative
maintenance visit. The detector will need to be calibrated in some cases when then spectrum peaks do
not match the blue line modeled peaks. For this case, a calibration will bring the peaks into alignment
with the modeled line. In other cases, labs may want to set a regular calibration schedule any time from
weekly to monthly.
Q5. What count rate should I use to calibrate?
A5. We recommend using a copper and aluminum sample with a primary beam at ≥ 20 kV. Adjust the
sample position so both Copper and Aluminum can be seen on the same screen. Set the position so the
Copper and Aluminum Kα peaks are similar in height, but with the Al peak larger than the CuK peak by
20 to 50%. Set the beam conditions so the Dead Time is ≤ 40% as you should use during normal use.

6.1
REMOTE DIAGNOSTICS
When possible, it may be useful to use a remote access program such as Teamviewer
to diagnose the system before an on-site visit. Remote access will allow an EDAX
engineer to examine log files, diagnose system operation and allow service-level
updates and adjustments to the detector. Using clues from remote diagnostics will
allow parts to be ordered in advance for an on-site visit if an on-site visit is required.
6.2 DETECTOR PROBLEMS
The detector is connected, and communicates with the software with a network connection. It is
possible a spontaneous computer glitch can cause a loss of communication with the detector. A typical
Element software login may show a RED indicator for the EDS hardware, as shown below, or display a
message about DPP service failing to start:
Common fix
Power PC Off
Power Detector OFF
Check cable connections
Power PC Back ON
Power the Detector ON
Should be Green
Figure 5 – TEAM Element Login - RED Hardware Status
In this case, power off the detector using the switch on the sDPP Box (see page 13) then reboot the PC.
Then power the detector back on when Windows has started.
If the detector shown in the Advanced Properties is not an Element detector, it could also be an
indication of loss of communication with the detector.
