The determination of trace elements in liquid samples such as seawater presents a number of challenges for Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The high dissolved solids content (approx. 3.5%) of seawater can supress analyte signal, cause interelement interferences and clog the interface sampler and skimmer cones. The seawater sample can be diluted, but at the expense of detectability, as some elements of interest in the 5 to 50ppt (ng/L) range. An alternative is a sample preparation that can selectively preconcentrate trace elemets of interest while having much less affinity for major matrix components such as Na, Ca and Mg.

The OmniPure Sub-Boiling Distillation System is a fully automated unit with all wetted parts composed of inert, high-purity Teflon PFA and FEP. The distillation assembly consists of a directly heated distillation container and an air-cooled condensation bottle. No external cooling system is required. The OmniPure uses a closed design with a standard storage bottle for collection, eliminating potential contamination from open-air or transfer bottles. The system is designed for easy disassembly, cleaning, and exchange of still assemblies. A sliding bottle rack with a built-in tray provides further ease of use, while protecting against accidental liquid spillage.

An integrated, ready-to-use sample dilution system, the SDS-550 comes complete with an ASX-520 autosampler and custom software. Variable dilution ratios from 1:1 to 1:50, multiple reagents with minimal changeover, large or small batch capacity, and diluent and reagent sequencing are all handled with a minimum investment of employee time and labor.
