Prin-Cen's ELSpe-2 PreCon automated enrichment, separation, and desalting system utilizes a chelating column to trap metal ions under specific conditions, leveraging their retention capabilities.
The system offers extremely high desalting efficiency and enables the enrichment of transition metals and rare earth elements. It represents an essential tool for analyzing these elements in high-salinity samples, such as seawater, alkali salts, alkaline earth salts, acid reagents, and basic reagents.
Key Features
- Excellent Desalting Capability: specifically designed for complex matrices where background salinity can reach up to 3.5% (such as surface ocean water), maintaining detection limits for heavy and transition metals at the ng/L level
- Full Automation: automated pre-concentration and matrix separation processes to reduce human error and increase data reproducibility.Selective Separation: Optimized for ultra-trace speciation analysis of hexavalent chromium Cr(VI)
- Maximum Flexibility with 4 Operating Modes: the system allows seamless switching between Enrichment/Desalting, Automatic Dilution Injection, Speciation Analysis, and Hydride Generation modes, adapting to every analytical need
- Ultra-High Sensitivity and Productivity: the combined action of matrix removal and the enrichment column dramatically lowers detection limits. The system ensures exceptional throughput with an analysis time of less than 3 minutes per sample
- Universal Plug-and-Play Compatibility: the ELSpe-2 PreCon module is designed to interface easily as a front-end system with all major ICP-MS models and brands available on the market.
