A microwave plasma atomic emission spectrometer is now available from Agilent Technologies. The 4100 MP-AES uses a nitrogen-based plasma which runs on air and, therefore, does not require flammable or expensive gases. With no external cylinder connections required and no need for on-going gas supplies, the spectrometer is suitable for any elemental analysis laboratory—especially remote sites and mobile laboratories. By eliminating the need to plumb multiple gases into the laboratory or manually transport and handle gas cylinders, laboratory safety is improved. Easy to use application-specific software applets automatically load a pre-set method, enabling users to start analysis without the need for method development or alignment. Minimal training is required and, since flammable gases are no longer required, the system allows for safe, unattended multi-element overnight operation.
