SP-IAA320 Atomic Absorption Spectrophotometer

The SP-IAA320 is a double beam atomic absorption spectrophotometer with a flame atomisation system, an 1800 lines/mm grating and a wavelength range of 190 to 900 nm. Wavelength accuracy is within ±0.5 nm, six spectral bandwidths from 0.2 to 5.0 nm are available, and the copper detection limit is 0.008 µg/mL or lower.

The double beam system compensates for source, wavelength and electronic drift to give a stable baseline, so hollow cathode lamps need little warm-up. A total reflection optical path increases light throughput, and the gas system uses precision pressure and flow stabilisation for a steady, low-noise flame. The titanium alloy burner is corrosion resistant and needs no water cooling, and quick gas changeover and safety devices support air-acetylene operation.

Built-in data processing covers peak height and area, deuterium lamp background correction and linear and non-linear curve fitting, with an RS232 interface for a PC. The instrument supports flame absorption, flame emission, graphite furnace and hydride generation methods.
