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.
