What should I know about the air supply for the nitrogen generator?

To avoid shortening its life, the nitrogen generator requires a supply of clean, dry, oil-free air. To assist in achieving this, the nitrogen generator has integral filters attached to the side of the unit. Depending on the quality of the air supply and the environmental conditions, additional driers and filters may be required. Refer to the Agilent MP-AES Site Preparation Guide for further details and read the instructions regarding filters under the Maintenance chapter of this guide. Under no circumstances should the nitrogen generator be operated without filters or with filters in a saturated condition. Under no circumstances should the nitrogen generator be connected to an air supply containing oil, as permanent damage to the nitrogen generator will occur. Contamination of the sorbent material with oil will invalidate the warranty.

What are the compressed gas hazards associated with the nitrogen generator?

Air compressors must be located and connected strictly in accordance with local safety codes and regulations. All compressed gases (other than air) can create a hazard if they leak into the atmosphere. Even small leaks in gas supply systems can be dangerous. Any leak (except that of air) can result in an oxygen-deficient atmosphere which can cause asphyxiation. The area in which cylinders are stored and the area surrounding the instrument must be adequately ventilated to prevent such gas accumulations. Do not directly inhale the output gas from the nitrogen generator. Periodically inspect the hoses to make sure they are in good condition and properly connected. Keep air hoses off the floor where they can be tripping hazards or become damaged. When disconnecting or connecting the hoses, make sure the hose is depressurized first. Always wear safety glasses when connecting or disconnecting gas lines.

---

What are the electrical hazards I should be aware of?

Panels or covers which are retained by screws on the nitrogen generator may be opened only by Agilent­trained, Agilent-qualified or Agilent­approved field service engineers (unless specified otherwise). The nitrogen generator is powered by an external AC-DC power supply. If the enclosure of this power supply is damaged it should be replaced immediately. Check the power cord for damage and replace it if it is visibly worn or damaged. If necessary, replace the power cord only with a cord equivalent to the one specified in the site preparation guide. Consult the manuals or product labels supplied with your air compressor for safety information and to determine which parts of it are operator-accessible.
