The brineFAST S4 is a high performance sample introduction system for the determination of trace impurities in brines and other high matrix samples by ICPOES. Early detection of low and sub-ppb alkaline earth and transition metals in high purity brines improves chlor alkali plant process control and prevents costly damage to fluoropolymer membrane cells. Undiluted 30% brines may be sampled and analyzed directly, eliminating offline sample preparation and reducing contamination.
Chloralkali plant process control
The brineFAST S4 is ideal for membrane cell chlor alkali plants, which require very reliable quantification of < 5 ppb Ca, Mg, and other elements in 30% ultrapure brine to prevent costly membrane damage. With traditional ICP techniques, detection limits in 30% brine are insufficient to provide plant engineers with precise and accurate results at the required concentrations. With the reliable daily operation and improved detection limits of the brineFAST, plant engineers can ensure product specifications are maintained with fewer process adjustments and chemical inputs.
For non-membrane cell chlor alkali plants, the brineFAST S4 can be run in direct mode, allowing automatic, inline dilution of samples to limit matrix exposure in the ICP and significantly reduce ICP maintenance. The preconcentration features may still be used when necessary to improve detection limits.
Chloralkali product monitoring and certification
The brineFAST provides a convenient and powerful way to measure trace elemental impurities in chlor alkali plant products, such as sodium hydroxide and sodium hypochlorite. These products can be measured with minimal sample preparation using the same instrument methods and conditions as the ultrapure brine analysis. Characterizing final products with the brineFAST provides high-precision, long-term data trends, which can benefit plant sales.
