LSPEC-YZ-600 Integrated Flame-Graphite Furnace Atomic Absorption Spectrophotometer
Product advantages
1. Total internal reflection optical system, full-band achromatic correction, automatic wavelength scanning and peak detection.
2. Features deuterium lamp subtraction background and self-absorption subtraction background.
3. Uniquely designed all-titanium burner ensures stable combustion and rapid thermal equilibrium.
4. Automatic adjustment of negative high voltage and lamp current, automatic positioning of optimal element lamp location, automatic ignition, and automatic flame-out protection.
5. 8-lamp rack (with optional 2 high-performance lamps) automatic control system. Enables comprehensive adjustment of hollow cathode lamps to optimal positions. Allows individual setting of specific element lamp positions. Permits free configuration of working lamps and preheating lamps, maxim ising savings in element lamp preparation time.
6. Graphite furnace heating: Users may freely define heating profiles as required.
7. Advanced constant-power temperature control design for graphite furnace: Ensures uniform graphite tube temperature distribution and maintains excellent dynamic stability at operating temperatures, guaranteeing analytical accuracy.
