The ZEEnit ® Series. Decades of experience in the development of spectrometers, plus the most recent findings made in electronics, magnetic field technology and furnace design, have gone into the ZEEnit P series.

Third-generation magnetic field technology

The variable magnetic field strength up to 1.0 Tesla and the use of two different correction modes guarantee maximum sensitivity and optimum matching to any analytical problem. Expansion of the linear working range by means of the 3field technique, and a dynamic mode for automatic adaptation to varied element contents – the ZEEnit opens up unparalleled capabilities in Zeeman graphite furnace AAS.

Transverse-heated graphite furnace

The future-oriented furnace heating concept can cope with a variety of samples, including complex matrices and refractory elements, due to:

·    Uniform temperature all along the optical axis throughout the tube

·    Lower atomizing temperatures

·    Elimination of vapor inferences

·    Minimizing of memory effects

·    STPF concept


The ZEEnit series comprises the ZEEnit 650 P, a Zeeman AAS for graphite furnace and hydride techniques, and the ZEEnit 700 P, a compact tandem spectrometer for flame, hydride, HydrEA and graphite furnace techniques. Both instruments are designed to analyze liquid and solid samples in one single device.
