  • Monochromator/Optics: 250mm Ebert mount, 600 lines/mm grating, 0.2-0.7-2.0nm bandpass
  • Hollow Cathode Lamp Supply: Triple HCL power supply; 3 to 75 mA peak.
  • Background Correction: Deuterium - In-Line (see-through) configuration, pulsed illumination, hot cathode, variable frequency, corrects from 190-350nm (0.7nm slit).
  • Burner/Nebulizer: Polypropylene spray chamber with pre-mix burner and high efficiency adjustable nebulizers (SS), Titanium burner heads for Air/Acetylene, Argon/Hydrogen and Nitrous Oxide/Acetylene operation.
  • Microprocessor: Computer control by 80C188 chip, 8/16 bit operation, 12/24 MHz clockspeed; non-volatile SRAM storage of >200 method files.
  • Integration/Response Range: User selectable times from 0.5 to 10 seconds for continuous (flame) and transient (furnace, hydride) signals.
