Hardware. System. True dual beam Echelle optics system. Front surface reflective optics with protective coating. Deuterium background corrector and two built-in EDL power supplies. Optical system. Echelle monochromator. Focal length: 300mm Grid: Area 36 x 185 mm, 79 lines/mm, blaze angle 76?. Fused quartz prism: 95 x 40 mm, 60°. Wavelength: 189-900 nm. Spectral bandpass: 0.15 nm at 200 nm. Reverse linear dispersion: 2.4 nm/mm. The photometer optics are covered to protect against dust and corrosive fumes. For maximum protection, the optical system can be purged with an inert gas. Detector. High performance, segmented solid state detector. Light sources. Hollow cathode or electrodeless discharge lamps (EDLs). EDLs offer significantly higher luminous efficacy and a longer service life compared to conventional hollow cathode lamps. Lamp elements, recommended operating currents and gap selection are automatically detected and adjusted when PerkinElmer® Lumina™ Series AA lamps are used. The lamp alignment is carried out fully automatically with the four-lamp tower. E-Box. All electronics are contained in a single, user-replaceable module that can be easily replaced by the operator without the need for a service technician. Gas control and burner system. Flame gas. Fully automated gas box with computer controlled oxidizer selection, automatic gas sequencing, oxidation and fuel monitoring and control. Steering. Software activated ignition with air/acetylene. The acetylene flow is automatically adjusted when switching to nitrogen oxide/acetylene operation or vice versa. Flame safety features. Fully interlocked operation prevents ignition if the proper burner head, atomizer, end cap or burner drain system is not installed properly, the liquid level in the receiver is incorrect, or the gas pressure is too low. Interlocks automatically shut off the gases when no flame is detected. The flame is automatically and safely extinguished in the event of a power failure or when using the emergency stop flame button. Burner system. An inert polymer mixing chamber provides superior analysis of corrosive and matrix-rich samples. The spray chamber is made of a high-strength composite material, eliminating the need for pressure relief devices. The high precision inert atomizer maximizes stability and sensitivity. A 10cm single slot solid titanium burner head for air/acetylene operation is included. Optional torch heads include: 5cm nitrous oxide/acetylene, 10cm triple slot air/acetylene and 5cm single slot air/acetylene. Sample area. 25cm wide x 25cm deep sample chamber for easy access to burner components. This Perkin Elmer AAnalyst 400 AA Spectrometer System was just removed from a working laboratory. Contains:.
