| Definition | A fully-integrated benchtop atomic absorption spectrometer that determines the elemental composition of a sample through the amount of light energy absorbed at specific wavelengths in the range 190-900 nm. The instrument contains an 8-lamp holder with built-in power supplies for hollow cathode and electrodeless discharge lamps, allowing automatic lamp selection. The instrument uses a real-time double-beam optical system (single-beam for Zeeman furnace operation) and includes both a flame and a Transversely Heated Graphite Atomizer furnace for atomisation of the sample. The specific wavelength of light to be measured is isolated by a monochromator and absorption is measured by a solid-state detector, with a built-in low-noise CMOS charge amplifier array. The burner is equipped with a high-strength inert mixing chamber and includes an adjustable nebulizer and an all-titanium, 10-cm, single-slot burner head. The instrument has a modulated 0.8 Tesla magnetic field oriented longitudinally to the optical path and a built-in continuum source double-beam background correction for flame operation. There is also a furnace autosampler which contains a removable sample tray. | |
