Description

SavantAA Σ is our top-of-the-range AAS.

It is a state-of-the-art fully automated, multi-element, true double beam instrument with all-reflective optics. It has all the features of the SavantAA plus:

  • Automated motorized workhead
    adjustment (vertical and horizontal).
  • Automatic Burner Rotation.
  • Super Lamp Power Supply.
  • Coded Lamp Recognition.
  • Electronic Sample Viewing.

Features

  • Eight lamp fully automated turret with auto alignment of lamps for sequential multi-element analysis.
  • Programmable flame control with ten safety interlocks provides reproducible operation with gas flows automatically set when changing methods.
  • All-reflective optics for high light throughput.
  • Automatic wavelength setting, 175 to 900 nm.
  • Continuously adjustable slit width 0.1 to 2.0 nm in 0.1 nm increments in both normal and reduced height with automatic setting.
  • Asymmetric modulation reduces noise by up to 40%.
  • Hyper Pulse fast background correction provides 175-423 nm correction range, at up to 2.5 Abs.
  • Coded lamp recognition.
  • Super Lamp Power Supply for 1 lamp (optional 4 lamp SLPS).
  • Motorised workhead adjuster.
  • Automatic burner rotation.
  • USB communications.

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°.

Performance Guarantee
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 ∑.
