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. 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.

EPA Method 8015D

How would you like even faster times on both GC and LC for emerging contaminants? In the first study, we analyzed the 20 target perfluorinated alkyl acids listed in EPA method.

Superficially porous particles SPP have been proven to provide fast and efficient separations with lower back pressures. While the federal government characterizes total 8015e 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.

National Ep Monitoring Conference. Optimized method-specific chromatograms will also be presented. Check Out Our Industry Pages! Who said there is no free lunch? In this presentation, we will look at two environmental analyses where speed, sensitivity, and selectivity are of importance. Since the beginning of the U.

This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step. Pharmaceuticals and personal care products PPCPs encompass a family of compounds used by individuals for health and cosmetic purposes; however, it is difficult 8105d eliminate the presence of these residues from water. In the chromatography world, a faster run time can easily be equated to improved productivity for your laboratory. A Company of Owners. Cookies allow for a variety of features that make your visit to Restek more enjoyable.

Recent developments at Restek for some common challenging environmental samples will be presented by our environmental application experts. During that same time period, overfuel releases were reported [1]. This site requires that Javascript be enabled.

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.

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.

Currently viewing desktop site. The 5-gram silica gel cartridge specified in these methods needs to achieve adequate separation of the two fractions with minimal interferences. Please enable Javascript in your browser.

Monitoring for the presence of PPCPs in ea water has become of great eppa due to their potential impact on human health. For more information, see our privacy policy. Are you more of a GC person? 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 epw their persistence in the environment.
