The ZEEnit 700 P represents a new generation of variable compact tandem spectrometers for flame mode, hydride, HydrEA and graphite furnace technology. It is able to analyze liquid and solid samples in one and the same system.

At a glance

• 8-lamp turret suited for coded lamps
• Transverse heated graphite tube furnace
• Furnace camera to monitor and control sample introduction and combustion in the graphite tube
• Deuterium and 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
• Superior aspherical optical system with extraordinary components, such as a quartz coated toric mirror, provides excellent light throughput
• Magnetic field technology, 3-field mode for extension of the linear concentration range
• Two atomizers combined in a single instrument allow switching between flame, hydride and graphite furnace techniques without any mechanical movement

High sample throughput

• Variable sample introduction technique capable of easily processing both liquids and direct solids making it unique
• High performance autosampler MPE featuring functions such as intelligent dilution and enrichment makes over-night processing routine and guarantees the highest dosing precision
• High sample throughput, variability and efficiency ensured by the dual atomizer concept

solid AA® — Direct analysis of solid samples

The transversely heated graphite furnace facilitates the introduction of liquid samples as well as direct solid sample feed. The combination of the furnace with powerful background correction forms the basis for optimal results.

The new contrAA® 800 series for HR-CS AAS cumulates the experience gained over the years, feedback and suggestions from the field and our experts’ refreshingly new ideas.

With its automatic atomizer switching and two-dimensional atomizer alignment, the contrAA® 800 is a versatile all-rounder that comes in a modern, space-saving design. A redesigned high-performance optical system provides improved stability and lowest noise, resulting in market-leading detection limits and superior accuracy. A new lamp design further reduces consumables costs. Analytik Jena highlights its expertise in high-performance optics with a unique long-term warranty of ten years on the optical components.

The newly developed Dynamic Mode makes use of flexible spectral evaluation parameters and enables extension of the dynamic working range up to five orders of magnitude with a single calibration curve. This helps users reduce sample preparation and dilutions to a minimum because the contrAA® is able to adapt itself to any analyte concentration present in your samples – from the ppb- to the percent-range.

Software

ASpect CS software package

The ASpect CS software offers comprehensive on-line help and a user-friendly software concept for applications ranging from routine analysis to development and research. The software supports the unique features of HR-CS AAS, such as:

• Simultaneous background correction by acquiring spectral information in the vicinity of the analysis line
• Fast element/line change
• Fast sequential multi-element measurement at continuous sample flow in flame mode
• Diverse options of automatic method optimization for work in all fields of application or with unknown matrices
• Cookbook methods for all elements — basis for fast method development

The obtained data can be recalculated, exported to various file formats and printed out.

The results of the quality control measurements are automatically recorded on so-called QC charts.
