Atomic absorption spectrometer with electrothermal atomization for precise analysis of toxic metals at the trace level of Agilent 240Z/280Z AA

Agilent 240Z/280Z AA are atomic absorption spectrometers with an electrothermal atomizer designed for laboratories that require reliable analysis of toxic metals (Pb, Cd, As, Hg, etc.) in water, food, biological and environmental samples at the trace level. The devices operate in the graphite furnace mode, providing high sensitivity and minimal sample volume, which is especially important for complex and heterogeneous matrices. The systems are in demand in environmental monitoring, control and production laboratories, pharmaceuticals and SES/CSSEN centers. The optical circuit is made according to the Cherni Turner type with an automatic monochromator and a range of 185-900 nm, which ensures stability and repeatability of the results even with large series of samples. Background correction is organized using a specialized method that effectively eliminates interfering absorption in complex and cloudy samples. The graphite furnace uses constant temperature zone technology, which ensures uniform sample heating and minimal variation of results. Management is performed from an external Windows PC, standard platforms for atomic spectroscopy and LIMS systems are supported, which allows automating methods, monitoring and reporting. For the Agilent 240Z/280Z AA laboratory, it is a reliable tool for routine, fast and highly accurate analysis of toxic metals with low consumption of consumables. Key differences between Agilent 240Z AA and 280Z AA The main difference lies in the optical part. The Agilent 240Z AA model is equipped with a 250 mm focal length monochromator and 4 lamp sockets, which is suitable for laboratories with a limited set of detectable elements. The Agilent 280Z AA uses a longer focus (330 mm) and 8 lamp sockets, which provides increased resolution and convenience when working with a wide range of elements within a single device.
