ELSpe-2 PreCon Automatic Desalting Separation and Enrichment System
ELSpe-2 PreCon automatic desalting separation and enrichment system use chelating column to trap metal ions in specific condition by their retention capacity, the efficiency of desalt is ultra high , the transition metals and rare earth elements can be enriched, strong support for transition metals and rare earth elements analysis in high salt samples such as sea water\alkali salt\alkali earth metal salt\acid reagent\base reagent.
Product Advantages
◆ Superior desalting capability: The content of transition metals and heavy metals in open ocean seawater is typically at the ng/L level, while the matrix salinity is around 3.5%. The desalting efficiency of the ELSpe-2 PreCon system reaches up to 99.9%.
◆ Multiple analysis modes: It allows for the free switching of desalting/enrichment (pre-concentrate) analysis mode, automatic dilution injection analysis mode, speciation analysis mode, and hydride analysis mode, according to specific requirements.
◆ Ultra-high sensitivity and fast analysis speed: High desalting efficiency eliminates matrix interference, and the trace metal trap column enhances sensitivity. With an injection volume of 400 μL ,the signal-to-noise ratio for 0.1 ppb of Cd is greater than 1000, detection limits below 1 ppt can be achieved, and the analysis time of one sample is less than 3 minutes.
◆ High compatibility: The ELSpe-2 PreCon system can be connected to various mainstream brands and models of ICP-MS, enabling four analysis modes: desalting/enrichment, automatic dilution, speciation analysis, and hydride analysis.
