Selecting a purge gas

Take care when selecting a purge gas for your microscope. Use only nitrogen or dry air to purge the instrument.


Avoid fire and explosion hazard.

Never use a flammable or combustible gas to purge the instrument. Heat from the source or from laser absorption could ignite the gas.

The purge gas must be free of moisture, oil, and other reactive materials. Use dried are or nitrogen to purge the microscope.
