SavantAA is an atomic absorption spectrometer (AAS) developed by GBC Scientific Equipment and is recognized as the flagship and standard model of the brand. Representing the fifth generation of GBC’s AAS instruments, it combines advanced design with a long-standing reputation for precision and reliability. Key features of the SavantAA include a true double-beam system, background correction, and automatic wavelength optimization. It automatically selects and aligns various lamps for multi-element analysis and is compatible with graphite furnace operation.
Other prominent features include an 8-lamp turret with automatic lamp selection, a full-reflective optical system with quartz coating for mirror protection, and rapid background correction using Hyper-Pulse technology. The instrument is also equipped with advanced safety systems for flame management and fast background correction, ensuring optimal performance and high accuracy.
SavantAA is suitable for a wide range of applications, including chemical analysis and scientific research. It comes with a performance guarantee, ensuring absorbance greater than 0.9 Abs for a 5 mg/L copper solution with high precision and a standard deviation of less than 0.5%.
This true double-beam spectrometer can be tailored to your analytical needs and budget. Even in its basic configuration, it offers advanced features such as a programmable Gas Box, 8-lamp turret with automatic lamp alignment, automatic optimization of wavelength and slit width, and electronically controlled lamp current adjustment. Additional options include a Super Lamp power supply for 1 or 4 lamps, coded lamp detection, automatic burner rotation, and an electronic sample viewing system for live color monitoring — particularly useful for graphite furnace analyses.
The SavantAA is also available in a “SavantAA No Flame” version, which excludes the Gas Box and is compatible with a graphite furnace or hydride system for atomic absorption measurements. Control of the device is managed via the Windows-based SavantAA software, offering a powerful yet user-friendly interface.
The SavantAA includes a fully automated 8-lamp turret with auto lamp alignment, enabling sequential multi-element analysis. Its programmable flame control with ten safety interlocks ensures repeatable performance, automatically adjusting gas flows when switching methods. The fully reflective optical system is designed to maximize light throughput and features automatic wavelength selection within the 185–900 nm range.
The slit width is continuously adjustable from 0.1 to 2.0 nm, with full auto adjustment capability. Asymmetric modulation reduces noise by up to 40%. The Hyper-Pulse system provides rapid background correction across a 175–423 nm range and supports up to 2.5 Abs. Optional features include coded lamp recognition, Super Lamp power supply (optional for 1 or 4 lamps), automatic burner rotation, and USB connectivity.
| Feature | Description |
|---|---|
| Optics | Includes a true double-beam system with background correction and flame emission detection. It uses asymmetric modulation with a 2:1 sample-to-reference ratio for noise reduction. All reflective optics are quartz-coated to protect mirrors from dust and vapors. Optional ESV (Electronic Sample Viewing) allows live sample compartment viewing. |
| Monochromator | Ebert-Fastie design with 333 mm focal length, self-calibrating. Operates over 175–900 nm wavelength range. Features a holographic grating (1800 lines/mm), Dual-Blazed profile, and 1.6 reciprocal linear dispersion. Automatic wavelength selection and peaking. Continuously adjustable slits from 0.1 to 2 nm (0.1 nm increments). Supports full bandwidth reduction for furnace operation and auto-slit width/height adjustment. Uses wide-range multi-alkali photomultiplier tube. |
| Lamp Turret | 8-lamp turret with fully automated selection and alignment. Automatically optimizes each lamp on both X and Y axes for maximum light throughput, enabling fully automated multi-element analysis. Automatically preheats the next lamp in sequence to avoid analysis delays. Optional coded lamp recognition and Super Lamp power supply (for 1 or 4 lamps). |
| Background Correction | Utilizes Hyper-Pulse technology at 200 samples/sec (50 Hz) or 240 samples/sec (60 Hz) for rapid peak background correction. High accuracy through ~1 ms pulse spacing and interpolation between measurements. High-intensity deuterium arc lamp covers 175–425 nm and supports up to 2.5 Abs background correction. |
| Flame Atomization System | Pre-mix design with corrosion-resistant inert polymer mixing chamber. Burner made entirely of titanium for durability. Optional nitrous oxide burner minimizes carbon build-up. Nebulizer includes platinum–iridium capillary and inert venturi, resistant to acid attack. Sample uptake adjustable via locking mechanism. Optional inert impact bead. Safety interlock between nebulizer and pressure relief valve. Integrated liquid trap with liquid level locking system. Quick-mount system allows easy conversion to graphite furnace. |
| Performance Guarantee | Capable of delivering absorbance >0.9 Abs for a 5 mg/L copper solution with relative standard deviation (RSD) <0.5% in replicate measurements. Ensures high precision and reproducibility in electrochemical measurements. |
