• Minimize or eliminate exposure to magnetic fields wherever possible
• Some wireless devices may also affect instrument performance. If this type of interference is suspected, move all wireless devices at least 2.0 m (6.5 ft) away from the instrument.

Safety Precautions

Purge Requirements

• The instrument contains precise optical components that may be damaged by a moist environment.
  • It is recommend to install a source of clean, dry air or nitrogen to purge the spectrometer.
  • It is especially important if humidity levels are above 70% RH in the laboratory environment
• Optical damage caused by failure to maintain the desiccants or to purge the spectrometer is not covered under your warranty.
• You may also have a laboratory environment that contains solvents or other agents that can corrode spectrometer components.
  • Purging the spectrometer will better protect the components.
• The interaction of chlorinated solvents, perfluorochlorinated solvents, or other solvents containing halogenated hydrocarbons (for example, Freon®) with an IR source can corrode spectrometer components.
  • Do not leave these solvents exposed around the spectrometer any longer than necessary.

Selecting a Purge Gas
WARNING Avoid explosion hazard.
Never use a flammable, combustible, or toxic gas to purge this instrument. The purge gas must be free of oil and other reactive materials. Heat from the source or from laser absorption may ignite flammable gases or reactive materials in purge gas. Use only dried air or nitrogen to purge your instrument.

Dry air and nitrogen are equally effective in eliminating water vapor and volatile solvents, but nitrogen will remove carbon dioxide from your spectrum more effectively. The purge gas must be free of moisture, oil, and other reactive materials. To remove particulate matter and oil, you may need to install a 10-micrometer filter. Dry air or nitrogen supplied for purge should be dried to a dew point of -70 °C (-94 °F) or below for best performance.

NOTICE Do not use argon as a purge gas. Argon is an insulator and prevents the system from cooling properly.

Installing Purge Gas Fittings
If you plan to purge the instrument, you must install the purge line and on/off valve before the instrument arrives. The source line pressure delivered to the pressure regulator must be at least 1.4 bar (138 kPa, or 20 psig) and must not exceed 7 bar (700 kPa, or 100 psig), with a minimum flow rate of 20 SCFH.

A pressure regulator is required at 20 psig. If the purge kit was purchased with the system, our service representative will install a pressure regulator and flowmeter. These components will maintain pressure and flow for optimal data collection. See the “Service” section of the user guide for more detailed information.

Note It is important to have all system utilities installed before the spectrometer arrives. Utility installations must comply with all local building and safety codes.

Purge Gas Generators
If your facility does not have a source of clean, dry compressed air or nitrogen for system purge, we recommend using a purge gas generator. It cleans and dries the air supplied by an air compressor so it can be used to purge the instrument. If your facility does not have an air compressor, a complete dry- air generating system is available. Contact our sales or service representative in your area for more information.

NOTICE If you are using a purge gas generator:

• Position it as far from the instrument as practical to reduce noise and vibration.
• Purge gas generators require a minimum pressure for proper operation. Failure to supply this pressure may allow moisture to enter the system, causing permanent damage.
• Read the manufacturer’s instructions before installing air-drying equipment or performing any maintenance. The installation and maintenance of air-drying equipment is your responsibility. Failure to perform routine maintenance as specified by the manufacturer may void your instrument warranty.
• Before connecting a new air dryer to the instrument, it is vital to purge the dryer of water and particulates by running it for at least 12 hours at nominal air flow. Otherwise, there is risk of severe damage to the instrument when you connect the pure air dryer.
