Page 8: Verifying Safe State
Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the instrument. Agilent Technologies assumes no liability for the customer’s failure to comply with these requirements. -
Page 9: Heat, Vapors And Fumes
Safety Practices and Hazards Always use a 3-wire outlet with ground connection that is adequately rated for the load. The installation must comply with local and national safety regulations. Use only an Agilent supplied power cord. Replace the power cord only with a cord equivalent to the one specified in the AA Site Preparation Guide. -
Page 10: Compressed Gases And Cylinders
Safety Practices and Hazards heat-sensitive devices. Do not make solder joints in the ducting—the hot exhaust in the duct may melt the joint. Regularly check the system by smoke test to ensure that the exhaust system is working. When operating the atomic absorption spectrometer, always have the chimney in place to ensure correct ventilation. -
Page 11: Gas Hoses And Connections
Safety Practices and Hazards Remember that for cylinder connections, left-hand thread fittings are used for fuel; right-hand thread fittings are used for support gases. When your analytical program is complete, or at the end of the working day, always ensure that all gas supplies are turned off at the cylinders. Gas hoses and connections Even small leaks in gas supply systems can be dangerous. -

Make sure that all peripheral devices are also certified. Make sure that appropriate cables are used to connect the device to peripheral equipment. Consult your equipment dealer, Agilent Technologies, or an experienced technician for assistance. Changes or modifications not expressly approved by Agilent Technologies could void the user’s authority to operate the equipment. - Page 16 Safety Practices and Hazards Remember always that the combination of a flame and flammable solvents can present a serious hazard. All relevant safety practices governing the use of flammable solvents must be strictly followed. To reduce the possibility of fire or explosion: When initially selecting an organic solvent, choose a solvent having the ...

Page 18: Nitrous Oxide
Safety Practices and Hazards Use only acetylene that is packed in acetone. Some gas suppliers offer acetylene packed in material other than acetone. While these alternatives may overcome some of the disadvantages of acetone, they may also introduce the more serious problem of corrosion in the gas control module and must not be used with Agilent atomic absorption spectrometers. -
Page 19: Burners
Safety Practices and Hazards Burners Improper or careless use of burners can create explosion hazards and fire hazards that can cause death, serious injury to personnel and damage to equipment and property. Whenever you handle burners, remember that the burner may be very hot. Always use protective gloves to handle burners. -
Page 20: Nebulizer
Safety Practices and Hazards Nebulizer Incorrect assembly and fitting of nebulizers to an atomic absorption spectrometer can create explosion hazards and fire hazards that can cause serious injury to personnel and damage to equipment and property. Ensure that the nebulizer is correctly assembled and correctly fitted to the spray chamber before lighting the flame. -
Page 21: Heat Hazards
Safety Practices and Hazards Heat hazards An open flame, burners, and other hot surfaces can present heat hazards that can result in severe burns. When operating a flame system, always operate your spectrometer with the flame shield closed, and the sample compartment front panel in place. Keep your hands out of the sample compartment while a flame is burning. -
Page 22: Flashbacks
Safety Practices and Hazards When solvent extractions of perchloric solutions are performed, some of the acid NOTE may dissolve in the organic solvent that is subsequently aspirated. Also, if the organic solution is aspirated while floating on the surface of the acid, do not allow the capillary tube to drop below the organic layer and suck up aqueous perchloric acid. - Page 23 Safety Practices and Hazards When using an organic solvent, a reduced uptake rate should be used to restrict the amount of liquid fuel that is fed to the flame. The width of the burner slot must not exceed the maximum design specification [Mark VIA: 0.47 mm (0.0185 in) for N O;...

Page 24: What To Do In The Event Of A Flashback
Safety Practices and Hazards As free acetylene is unstable at elevated pressure, it has to be stored in the cylinder by dissolving it in acetone. If the gas is withdrawn too quickly, or the cylinder pressure is allowed to drop below 700 kPa, acetone may be drawn off in sufficient quantities to affect analytical performance, damage seals, O-rings and hoses, or even cause a flashback. -
Page 25: Furnace And Zeeman Operation
Safety Practices and Hazards Furnace and Zeeman operation Gases The graphite tube atomizer gas supply system is designed for use with inert gases and air. Never use pure hydrogen with the graphite tube atomizer since this could result in leakage and potentially explosive accumulation of hydrogen. You may, however, use a proprietary, prepackaged mixture of 95% argon (or nitrogen) and 5% hydrogen. - Page 26 Safety Practices and Hazards This page is intentionally left blank.
