EmailThe 2010 Flame–Graphite Furnace Dual-Mode Atomic Absorption Spectrophotometer is compact yet powerful. It supports seamless switching between flame atomization and graphite furnace atomization, making it adaptable for analyzing a wide range of elements. Equipped with advanced deuterium lamp background correction, it is well-suited for complex sample matrices and is widely used in scientific research, environmental monitoring, biomedical, and chemical industries. Its robust software and hardware systems enhance analytical accuracy, safety, simplicity, and speed.
Features
8-Lamp Auto Switching: Automatically switches between 8 element lamps with simultaneous preheating, saving significant time.
Advanced Dual-Beam Platform: Enables automatic wavelength scanning and peak searching for precise spectral alignment.
Dual Background Correction: Combines self-absorption and deuterium lamp correction to improve accuracy for complex samples.
Multimedia Graphite Furnace Visualization: Real-time monitoring of drying, ashing, and atomization inside the graphite tube; simplifies maintenance and replacement.
PID-Controlled Optical Heating: Ensures excellent sensitivity and repeatability through precise temperature control.
Independent Gas Flow Control: Separates internal and external gas flows—external gas remains on during analysis, while internal gas is paused during atomization—to protect the graphite tube and enhance sensitivity.
Comprehensive Safety Protections: Graphite Furnace: Monitors water pressure, gas pressure, tube contact, furnace body, and current. Flame System: Monitors gas pressure, acetylene leakage, and flame status.
