A Dissolved-Particulate Baseline Study of PAHs in Particulate-Laden Water
August 31st 2008When water samples are extracted and analyzed for PAH's, many methods require the sample to be filtered to remove particulate matter. This helps reduce SPE cartridges 'plugging' or emulsions forming, as can happen with conventional liquid-liquid extraction. But, filtration of the suspended particulate matter may reduce the effectiveness of the extraction for PAHs. Therefore, to determine the actual concentration of PAHs, the "whole" watersample, with the suspended particulate matter, needs to be processed. In this study, SPE using a 47mm "disk" format, with an automated extractor system, is proven as a successful, reproducible, analytical extraction method for particulate laden water samples for PAHs.

Trace Analysis of Perchlorate: Analytical Method and Removal Efficiency of Purification Technologies
August 31st 2008Perchlorate recently has received attention as an environmental pollutant. Perchlorate can affect human health by interfering with iodide uptake by the thyroid gland and disrupting thyroid function. Perchlorate-free purified water is needed by laboratories analyzing samples for the presence of perchlorates.
