ZEEnit is the plus in your laboratory. It convinces with its cost efficiency, fast and reliable analysis and excels in the analysis of samples with high matrix.

Zeeman AAS for Demanding Samples

The ZEEnit series is designed for routine trace analysis in demanding matrices. The systems combine an outstanding graphite furnace concept with the most powerful and latest generation of Zeeman effect background correction and D2 background correction

• Variable magnetic field strength (2Field/3Field and Dynamic Mode) – maximum sensitivity and expansion of the linear working range
• Included intelligence like automatic calibration and sample dilution and wide range of accessories to maximize the productivity, safety and ease of use
• Direct analysis of solid sampling upgradable

Proven Zeeman Technology

Atomic absorption spectrometry is a proven technique for the determination of elements in the medium to low concentration range. A special challenge is the trace analysis of toxic elements in difficult matrices. To meet this requirement, Analytik Jena offers the ZEEnit series of reliable analytical instruments with the proven Zeeman AAS technology. The Zeeman background correction used here is one of the most powerful background corrections in the field of AAS and ensures reliable results.

Both Zeeman AAS, the ZEEnit 650 P and the ZEEnit 700 P, are compact spectrometers equipped with a transversally-heated high-performance graphite furnace. The Zeeman magnetic field control for Zeeman background correction enables variable adjustment of the magnetic field strength up to one Tesla in various possibilities, the 2-field / 3-field and dynamic mode, thus providing maximum sensitivity and an extended working range. The systems are also equipped with a powerful deuterium background correction.

The ZEEnit 700 P provides furthermore a fully automatic flame mode, which is available in a second sample compartment, thus covering a wide concentration range.The operation of the systems is simple and user-friendly, as many processes are automated. This is implemented in a compact design by numerous integrated components, such as a carousel for 8 hollow cathode lamps, an RFID tool for the use of coded hollow cathode lamps as well as super lamps, a sampler for graphite furnace technology with automatic dilution function and a furnace vision tool. Pre-programmed methods for typical applications as well as a quick start function in the software allow a quick start for routine applications. With the combination of the unique direct AAS solids sampling and the ZEEnit graphite furnace technology, the effort for sample preparation can be minimized.
