The ELSpe-2 hexavalent chromium analyzer is a dedicated system for the determination of ultra-trace hexavalent chromium in soil, solid waste, water, toys, leather and food with high sensitivity, high throughput, high accuracy, high speed, high resolution, full automatic and simple operation.
The industry's first dual ion chromatography pump system reduces infusion pulses, lowers baseline noise, and improves the signal-to-noise ratio; the unique ultra-long optical path TLD detector delivers the highest sensitivity among similar products.
The "WATER ONLY" hexavalent chromium analysis kit, combined with an interference matrix removal column, greatly reduces matrix interference in samples and ensures measurement accuracy.
The high-capacity 120-position EAS-2A autosampler features pre- and post-injection washes and an overlap injection mode to minimize waiting time and reduce total analysis time. The dedicated Cr(VI) analytical column achieves complete separation in 3 minutes, cutting separation time in half compared to competitor columns.
The "water only" column and reagent kit, along with optimized system configuration and validated method setup, simplify sample analysis workflows.
The Ultra Trace Hexavalent Chromium Analyzer can be expanded to test nitrite, bromate, silicate, borate, iron, copper ion, zinc ion, nickel ion, and other analytes by adding analysis packages. It can also function as a standalone ion chromatograph (IC) and be coupled with IC-ICPMS for elemental speciation analysis (including As, Cr, Hg, Se, Sb, Br, Sn, Fe, Mn). Additionally, it can be used as a standalone formaldehyde analyzer for formaldehyde detection.
