The 5-gram silica gel cartridge specified in these methods needs to achieve adequate separation of the two fractions with minimal interferences. By reducing oven volume, these inserts allow faster ramp rates to be attained, which reduces oven cycle time and allows for increased sample throughput and more capacity to process rush samples.

This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step. During that same time period, overfuel releases were reported [1]. For more information, see our privacy policy. Perfluorinated compounds are of concern due to their potential health effects and their persistence in the environment. Superficially porous particles SPP have been proven to provide fast and efficient separations with lower back pressures.

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. Optimized method-specific chromatograms will also be presented.

This site requires that Javascript be enabled. Monitoring for the presence of PPCPs in drinking water has become of great interest due to their potential impact on human health. In the first study, we analyzed the 20 target perfluorinated alkyl acids listed in EPA method.

Check Out Our Industry Pages! Currently viewing desktop site. Since the beginning of the U.

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.

One of the earliest of these methods eps devised by the Massachusetts Department of Environmental Protection.

Are you more of a GC person? How would you like even faster times on both GC and LC for emerging contaminants? Who said there is no free lunch? States that have published methods using fractionation are challenged with proper elution of these petroleum products. By using this website, you agree to the use of cookies in accordance with our guidelines. In this presentation, we will look at two environmental analyses where speed, sensitivity, and selectivity are of importance.


Recent developments at Restek for some common challenging environmental samples will be presented by our environmental application experts. 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.

National Environmental Monitoring Conference. 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. 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.

EPA Method 8015D (SW-846): Nonhalogenated Organics Using GC/FID

By decreasing particle size, SPP particles offer even more efficiency than traditional fully porous particles of the same size. A Company of Owners. The advantages of superficially porous 8015c will be demonstrated in the fast analysis of both PPCPs and PFCs, with both excellent peak shapes and separations.
