The Macylab AA-1800E is a multifunctional Atomic Absorption Spectrophotometer designed for the analysis of complex samples. Operating in the 190nm to 900nm wavelength range, it integrates a flame analytical system, a graphite furnace analytical system, and supports hydride generation into a single platform.
Built with an 1800 lines/mm large area grating monochromator and a fully closed optical system, the instrument can automatically switch between flame and graphite furnace operating modes. Through its control software, the AA-1800E supports automatic wavelength scanning, alignment, and unmanned automatic analysis for routine laboratory testing requirements.
Key Features
Flame & Graphite Furnace Auto-Switching: Controlled by the software, the instrument automatically switches between flame and graphite furnace modes, configuring the system for different concentration ranges and allowing automatic optimization.
Automatic 8-Lamp Turret: Features an automatic socket configuration that holds ≤8 independent lamp power supplies. It supports simultaneous preheating and automatic conversion to streamline multi-element workflows.
Optical Temperature Monitoring (Graphite Furnace): Utilizes a longitudinal optical temperature monitoring system that detects the graphite tube wall temperature. This enables programmable temperature control up to 3000°C.
Corrosion-Resistant Flame System: Equipped with a polymer material spray chamber that provides resistance to acids and alkalis, including hydrofluoric acid. It is paired with a titanium burner.
Precision Optical System: Employs a large 1800 lines/mm grating monochromator and an imported photomultiplier tube (PMT) detector, supporting a wavelength accuracy of ≤0.15nm and repeatability of ±0.1nm.
Automated Gas & Safety Control: The flame system automatically accomplishes safety ignition and extinction. The graphite furnace integrates specific alarm and protection functions for graphite tube damage, water flow, air pressure, and overheating.
