| Feature | Description |
|---|---|
| Optics | True double-beam system with background correction and flame emission capability. Asymmetric modulation with a 2:1 sample-to-reference ratio to reduce noise. Fully reflective optics with quartz-coated mirrors. Dust and vapor-sealed. ESV (Electronic Sample Viewing) provided as standard. |
| Monochromator | Ebert-Fastie design with 333 mm focal length, self-calibrating. Wavelength range: 175–900 nm. Holographic grating with 1800 lines/mm, dual-blazed profile. Inverse linear dispersion of 1.6. Auto wavelength selection and peaking. Continuously adjustable slits with spectral bandwidth from 0.1 to 2 nm (0.1 nm steps). Slit height reduction for furnace operation supported. Automatic slit width/height adjustment and scanning. Wide-range multialkali photomultiplier tube. |
| Lamp Turret | 8-lamp turret with automatic lamp selection and alignment. Each lamp is automatically aligned on x and y axes for maximum light throughput. Supports fully automated multi-element analysis. Next lamp is pre-heated automatically to avoid delays. Auto recognition of coded lamps (optional). Optional Super Lamp power supply supports 1 to 4 lamps. |
| Background Correction | Hyper-Pulse correction in SavantAA and ∑ SavantAA models. Sampling at 200 Hz (50 Hz) or 240 Hz (60 Hz) for fast peak correction. ~1 ms interval between pulses and interpolation method for high accuracy. High-intensity deuterium arc lamp covers 175–425 nm range. Background correction up to 2.5 Abs total absorbance. |
| Flame Atomization System | Pre-mix design with corrosion-resistant inert polymer mixing chamber. Burner fully made of titanium for durability and operational resistance. Optional nitrous oxide burner to reduce carbon deposits. Nebulizer with platinum-iridium capillary and inert venturi for acid resistance. Adjustable sample uptake with locking mechanism. Optional inert impact bead available. Interlock between nebulizer and pressure relief valve. Integrated liquid trap with liquid level lock. Quick-mount system enables easy switch to graphite furnace. |
| Motorized Flame Rotation | ∑ SavantAA includes motorized flame rotation. Allows flame angle adjustment as part of analysis method. Out-of-range samples can be remeasured at higher angles after recalibration. Flame angle adjustable with ±0.1° accuracy. Rotation range: 0° to 90°. |
| Performance Guarantee | ∑ SavantAA guarantees absorbance > 0.9 Abs for 5 mg/L copper solution with <0.5% RSD in the same measurement. |
