Waste Water Matrix Organics – American West Analytical Labs

The 5-gram silica gel cartridge specified in these methods needs to achieve adequate separation of the two fractions with minimal interferences.

During that same time period, overfuel releases were reported [1]. By using this website, you agree to the use of cookies in accordance with our guidelines. In the chromatography world, a faster run time can easily be equated to improved productivity for your laboratory. Monitoring for the presence of PPCPs in drinking water has become of great interest due to their potential impact on human health.

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 site requires that Javascript be enabled. In this presentation, we will look at two environmental analyses where speed, sensitivity, and selectivity are of importance. For more information, see our privacy policy.


In the first study, we analyzed the 20 target perfluorinated alkyl acids listed in EPA method. Check Out Our Industry Pages! 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.

In an attempt to expand the analyte list of concern and decrease analysis time still further, we analyzed 41 perfluorinated compounds PFCs on Raptor epz. 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.

Since the beginning of the U. Go to mobile site. 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. 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.

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

One of the earliest of these methods was devised by the Massachusetts Department of Environmental Protection. 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. Are you more of a GC person? National Environmental Monitoring Conference. 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.

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. This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step. States that have published methods using fractionation 80015d challenged with proper elution of these petroleum products.
