Flame And Graphite-Furnace Atomic Absorption Spectrophotometer CAAM-2001, 190-900 nm Wavelength Range (CAT#: STEM-AL-7008-ZJF)

This atomic absorption spectrophotometer is configured for integrated flame and graphite-furnace atomic absorption analysis. It is intended for quantitative determination of metallic and metalloid elements in laboratory samples. The optical system selects analytical wavelengths from element-specific light sources and directs the measurement beam through the atomization path. The system supports the analytical methods and element groups described in the source, including trace-level measurements where applicable. Instrument control coordinates wavelength selection, source operation, signal acquisition, and data processing. The atomization configuration is integrated with the main instrument to support routine method setup and sample measurement. Software and USB connectivity support data handling and interaction with external computing equipment. The configuration is suitable for elemental analysis in environmental, food, pharmaceutical, geological, metallurgical, agricultural, and related testing workflows.
