ZEEnit series - Recent technologies translated into a family of instruments that sets new standards

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 series (ZEEnit 600/650/700). The ZEEnit 700 completes yet another milestone in spectrometer development at Analytik Jena: A system that combines excellent analytical performance with a high degree of user friendliness.

On the ZEEnit 700, the core competency in optical design has been combined with "High-end technology" in atomizers. The transversely heated graphite furnace with all its highlights ensures maximum accuracy and operation according to the STPF concept. The third-generation Zeeman technique is unsurpassed in background correction - the variable magnetic field combined with the three-field technique and the dynamic mode are the basis for an extended linear working range and optimum sensitivity! The flame system, too, features a high degree of automation. The optimized burner/nebulizer system ensures that samples are optimally nebulized and atomized. A multitude of accessories allows the user to customize the system to the specific analytical needs.

At first glance:

  • Two atomizers combined in a single instrument allow switching between flame, hydride and graphite furnace technique without any mechanical movement
  • Transverse-heated graphite furnace
  • Third-generation Zeeman technology
  • Choice of two correction modes: Deuterium or Zeeman background correction
  • Automatic optimization routines for, Flame composition and burner height
  • Atomization and pyrolysis temperature, Magnetic field strength, two-field and three-field correction mode
  • Direct solid AAS
  • Intelligent sample-preparation stations
  • High sample throughput, variability and efficiency ensured through the dual atomizer concept
  • Modern software

 

Well thought-out concept for automated flame and hydride technique
  • High sample throughput, variability and efficiency ensured through the dual atomizer concept, modern software modules and versatile accessories.
  • Improved accuracy even with varying samples and element contents through the combination with fully automatic, intelligent samplers with integrated dilution function.
  • Unique background baseline correction for optimum operation in emission mode.
  • Efficient atomization of all samples by the combination of an adjustable impact bead and an atomizer with an inert mixing chamber.
  • Fully automatic gas control by Total Flow gas box and - in combination with automatic burner height adjustment - automatic optimisation of flame parameters.
  • Injection technique with the SFS 6 Segmented Flow Star for high matrix loads of samples, injection of small sample volumes and stable burner conditions.

The ZEEnit is a compact spectrometer with a new-generation of magnetic field technology.

The instrument provides a wealth of unique benefits:

  • Maximum integration of all components and minimum foot print
  • Temperature stabilized transversely heated graphite furnace for problem-free trace analysis according to the principles of the STPF concept
  • Sensorless true temperature control and unique emission independent temperature recalibration
    Variable power magnetic field to 1.0 Tesla.
  • Unique 3 field mode for extension of the linear operating range.
  • Directly combination of graphite furnace and hydride technique (HydrEA technique) for a higher efficiency of hydride analysis with clearly improved proof borders.
  • WinAAS® software with a convincing concept for simple operation and optimization options for routine work inclusive extencive ones quality asscurance.

New options in direct solid analytics:

The newly developed transversely heated graphite furnace used in the ZEEnit 600/650 facilitates the introduction of liquid samples as well as direct solid sample feed. The combination of the transversely heated graphite furnace with powerful background correction forms the basis for optimal results. In addition, the development of a specially optimised sample holder allows the analysis of various solids from powders to sample pieces. The geometry of the holder guarantees the ideal atomisation conditions in the solids tube and reliable transport procedures for sample introduction. The different manual or automatic autosamplers SSA 6z and SSA 600 for solids make the use of ZEEnit for direct solid analytics childsplay. The 3-field mode opens up a multitude of new possibilities, as significantly greater contents can be measured without dilution in a wide range of samples.
