Overview
The multi X 2500 from Analytik Jena is a versatile analyzer for halogen and carbon sum-parameter monitoring (AOX/TOX, EOX, POX, TX/TOX, TOC) in wastewater, sludge, soil and other challenging organic matrices. It combines simple operation, high automation, high throughput and low maintenance for routine and research laboratories.

Key features

• Broad application range: AOX, EOX, POX, TX/TOX, TOC sum parameters
• Double-furnace technology enabling both vertical and horizontal sample feeding in one system
• High sample throughput with accurate and reproducible results
• Low operating costs and reduced maintenance effort
• multiWin software for intuitive control and method management

Optimal adjustment for each sample matrix
The innovative double-furnace concept allows fast switching between vertical and horizontal combustion modes for optimal adaptation to each sample type.

• Easy handling and plug-and-start operation
• Reduced maintenance through optimized combustion and gas flow management
• High throughput in both vertical and horizontal modes
• Cooled titration cell with wide-range coulometer for stable long-term performance
• Speed load and compatible sample preparation systems for 24/7 operation
• Flame sensor for matrix-optimized quantitative combustion of unknown samples

Environmental and process analysis
Designed for environmental monitoring, process control and quality assurance: determination of organically bound halogens on activated carbon and flexible workflows for halogen sum-parameter analysis. The multiWin software supports easy method switching (column and batch), automation options and LIMS integration. Compatible with automated AOX sample preparation systems (APU, AFU series) to maximize throughput and minimize idle time.
