PerkinElmer AAnalyst 400 AA Spectrometer

Hardware

System 

True double-beam echelle optical system. Front surfaced, reflecting optics with protective coating. Deuterium background corrector and two built-in EDL power supplies.

Optical System 

Echelle monochromator. Focal length: 300 mm. Grating: 36 x 185 mm area, 79 lines/mm, blaze angle 76˚. Fused-quartz prism: 95 x 40 mm, 60°.Wavelength: 189-900 nm. Spectral band pass: 0.15 nm at 200 nm. Reciprocal linear dispersion: 2.4 nm/mm. The photometer optics are covered to protect against dust and corrosive vapours. For maximum protection, the optical system can be purged with an inert gas.

Detector 

High-efficiency, segmented solid-state detector.

Light Sources 

Hollow cathode or electrodeless discharge lamps (EDLs). EDLs provide much higher light output and longer lifetime when compared to conventional hollow cathode lamps. Lamp elements, recommended operating currents and slit selection are automatically recognized and set when using PerkinElmer® Lumina™ series AA lamps. Lamp alignment is completely automatic with the four-lamp turret.

E-box 

All electronics are located in a single user-replaceable module that the operator can easily replace without requiring a service visit. 

Gas Controls and Burner System

Flame Gas 

Fully automated gas box with computer-controlled oxidant selection, automatic gas sequencing, oxidant and fuel monitoring and control.

Control 

Software-actuated ignition with air/acetylene. Acetylene flow is automatically adjusted when switching to or from nitrous-oxide/acetylene operation.

Flame Safety Features 

Fully interlocked operation prevents ignition if the proper burner head, the nebulizer, end cap or burner drain system are not correctly installed, the level of the liquid in the drain vessel is incorrect, or gas pressures are too low. Interlocks will automatically shut down the gases if a flame is not detected. The flame is automatically and safely extinguished in the event of a power failure or when the emergency flame-off button is used.

Burner System 

An inert-polymer mixing chamber provides superior analysis of corrosive and high-solid matrices. The spray chamber is manufactured from a high-strength composite, eliminating the need for pressure-relief devices. The high-precision inert nebulizer maximizes stability and sensitivity. A 10-cm single-slot solid titanium burner head for air/acetylene operation is included. Optional burner heads include: 5-cm nitrous-oxide/acetylene, 10-cm three-slot air/acetylene and 5-cm single-slot air/acetylene.

Sample Area 

25 cm wide x 25 cm deep sample compartment for easy access to burner components.
