Pharmaceuticals and personal care products PPCPs encompass a family of compounds used by individuals for health and cosmetic purposes; however, it is difficult to eliminate the presence of 8015s residues from water.

National Environmental Monitoring Conference. Since the beginning of the U.

In this presentation, we will look at two environmental analyses where speed, sensitivity, and selectivity are of importance. In the first study, we analyzed the 20 target perfluorinated alkyl acids listed in EPA method. Monitoring for the presence of PPCPs in drinking water has become of great interest eap to their potential impact on human health. Check Out Our Industry Pages!

States that have published methods using fractionation are challenged with proper elution of these petroleum products. While the federal government characterizes total petroleum hydrocarbons TPH using EPA Method D, individual states have developed methods for determining toxicity of ea by separating the more toxic aromatics from the less toxic aliphatic hydrocarbons.

The 5-gram silica gel cartridge specified in these methods needs to achieve adequate separation of the two fractions with minimal interferences. Superficially porous particles SPP have been proven to provide fast and efficient separations with lower back pressures. During that same time period, overfuel releases were reported [1]. How would you like even faster times on both GC and LC for emerging contaminants?

Several key attributes, such as minimal background extractables, maximum resolving power of aliphatic from aromatic components, and consistent moisture control will be evaluated for their effects on performance.

By decreasing particle size, SPP particles offer even more efficiency than traditional fully porous particles of the same size. The advantages of superficially porous particles will be demonstrated in the fast analysis of both PPCPs and PFCs, with both excellent peak shapes and separations. Perfluorinated compounds are of concern due to their potential health effects and their persistence in the environment.

Optimized method-specific chromatograms will also be presented. In an attempt to expand the analyte list of concern and decrease analysis time still further, we analyzed 41 perfluorinated compounds PFCs on Raptor 1.

This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step. This site requires that Javascript be enabled. Are you more of a GC person?

With a scaled-down column, a properly translated method, and a GC Accelerator kit, you can obtain the same chromatographic separation—often with greater sensitivity—in a fraction of the time without making a capital investment. In the chromatography world, a faster run time can easily be equated to improved productivity for your laboratory. Download a PDF of the full presentation.
