Specifications
Optics :- Double beam with background correction and flame emission capability. Asymmetric modulation with 2:1 sample-to-reference ratio for noise reduction. All-reflective system with quartz overcoating on mirrors. Sealed against dust and vapour. ESV supplied standard.
Monochromator :- Ebert-Fastie design with 333 mm focal length and 175–900 nm wavelength range. 1800 line/mm holographic grating with dual-blazed profile and 1.6 linear reciprocal dispersion. Automatic wavelength selection and peaking. Continuously adjustable slits with 0.1 to 2 nm spectral bandwidth (0.1 nm increments). Reduced height for furnace operation available with all slit widths. Automatic setting of slit width and height. Automatic scanning. Selected wide range multi-alkali photomultiplier tube.
Lamp Turret :- Eight-lamp turret with automatic lamp selection. Automatic optimization in two planes for maximum light throughput. Automatic multi-element operation, with the next lamp in the sequence automatically warmed up. Compatible with standard hollow cathode lamps. Coded Lamp Recognition for ALL lamps and one lamp Super Lamp power supply. Optional four lamp Super Lamp power supply.
Background Correction :- Hyper-Pulse background corrector on the SavantAA and SavantAA ∑ takes 200 (50 Hz) or 240 (60 Hz) sample readings per second for correction of fast background peaks. With approximately 1 ms between pulses and interpolation between measurements, the best possible accuracy is assured. High intensity deuterium arc lamp provides 175–425 nm correction range. Corrects to 2.5 total absorbance.
Flame Atomization System :- Pre-mix design with solid inert polymer mixing chamber. All-titanium burner construction. The optional nitrous oxide burner is designed to reduce carbon build up. Nebulizer has platinum-iridium capillary and inert venturi for resistance to acid attack. Adjustable sample uptake rate with locking mechanism. Optional inert impact bead. Interlocked nebulizer bung and pressure relief bung. Integral liquid trap with liquid level interlock. SavantAA ∑ has quick-change mounting to enable easy change-over to graphite furnace. SavantAA ∑ has automatic motorized height and horizontal adjustment of the burner and graphite furnace workhead.
Automatic Burner Rotation :- The SavantAA ∑ has motorized burner rotation allowing the burner angle to be set as part of a method. Samples outside the calibration range can be automatically re-measured at a greater angle after a further calibration. Angle is settable to ±0.1° with a rotation angle from 0° to 90°.
Automatic Burner Rotation :- Greater then 0.9 abs for 5 mg/L copper solution with an RSD of less than 0.5% on the same measurement for the SavantAA ∑.
