contrAA^® 300

contrAA^® 300 is the High-Resolution Continuum Source atomic absorption spectrometer for flame and hydride technique.

contrAA^® 300 offers

• Just one continuum source of radiation – characteristic for the revolutionary High-Resolution Continuum Source AAS (HR-CS AAS)
• High-resolution echelle spectrometer
• PC-controlled and fully-automated operation
• Fast sequential and simultaneous multi-element analysis, at bulk concentrations and trace levels
• Fully-automatic, completely sensor-monitored sample introduction system
• Burner adjustment by maximum absorbance
• Reproducible burner position by scaled height and angle adjustments
• "Segmented Flow Star SFS6" for small sample volume and samples with strong matrix influence (salt, acid, etc.)
• Intelligent automatic dilution for flame and graphite furnace up to 1:625 and automatic contamination check with autosampler
• A large range of accessories
• Coupling with the hydride technique for a new range of detection limits for hydride forming elements, such as As, Se, Sb, Te, Bi and Sn

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

Accessories

Autosampler systems for flame, hydride and atomic fluorescence technique

• AS-F und AS-FD — autosamplers for flame technique
• Make the routine analysis of standards and samples almost fully automatic

Modular hydride systems

• Flow injection as well as batch mode available
• Systems can be upgraded at any time – it “grows” with the lab’s requirements
• Easy exchange between all configurations
• Color-coded tubing connections and flow scheme – easy replacement of consumables
• Upgrade to HydrEA, easy exchange between mercury/hydride and HydrEA
• Special mercury accessories
• Fast Baseline Return drastically reduces the measurement time for mercury
• Fully compliant with all applicable DIN, ISO, EPA and ASTM methods for mercury and hydride analysis

“Segmented Flow Star SFS 6”

• Two-way module for software-controlled metering of smallest volumes via time control
• Reduces risk of burner head slit blocking due to continuous intensive rinsing
• Minimizes necessity of cleaning intervals of the sample introduction system
• Minimizes problems while analyzing samples with high matrix contents (high acid and salt contents, protein etc.)
• Improves base line stability of the spectrometer (constant flame temperature)
• Can additionally be used for the analysis of organic solvents
• Complete maintenance free operation

Scraper

• Allows software controlled periodical cleaning during flame warm up and during sample measurements
• Ensures stable flame conditions
