Setting The Purge Gas Controls - Thermo Scientific Nicolet iS10 Using Manual

Setting the purge gas controls

You must connect a source of purge gas (dry air or nitrogen) to purge your instrument of
moisture and other environmental contaminants. For best results the purge gas should be
dried to a dew point of -70 degrees C (-94 degrees F) or below. Use the following instructions
to set the purge gas controls.
Notice: We recommend that you maintain seal and desiccation and/or purge your instrument
at all times. Equipment damage due to failure to maintain seal and desiccation and/or purge is
not covered under the warranty. If you have questions about this requirement, please contact
us.
Warning: Never use a flammable gas to purge your instrument. The purge gas must be
free of moisture, oil, carbon dioxide and other reactive or infrared-absorbing materials. To
prevent laser damage, use only dried air or nitrogen to purge your instrument.
