Who said there is no free lunch? 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. National Environmental Monitoring Conference. One of the earliest of these methods was devised by the Massachusetts Department of Environmental Protection. Are you more of a GC person?
In the chromatography world, a faster run time can easily be equated to improved productivity for your laboratory.

The 5-gram silica gel cartridge specified in these methods needs to achieve adequate separation of the two fractions with minimal interferences. The advantages of superficially porous particles 88015d 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. While the federal government characterizes total petroleum hydrocarbons TPH using EPA Method D, individual states have developed methods for determining toxicity of fuels by separating the more toxic aromatics from the less toxic aliphatic hydrocarbons.

In the first study, we analyzed the 20 target perfluorinated alkyl acids listed in EPA method. States that have published methods using fractionation are challenged with proper elution of these petroleum products. With a scaled-down column, eoa properly translated method, and a Ea 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 this presentation, we will look at two environmental analyses where speed, sensitivity, and selectivity are of importance. Monitoring for the presence of PPCPs in drinking water has become of great interest due to their potential impact on human health. Optimized method-specific chromatograms will also be presented.
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 these residues from water. This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step.
