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.

Perfluorinated compounds are of concern due to their potential health effects and their persistence in the environment. A Company of Owners. One of the earliest of these methods was devised by the Massachusetts Department of Environmental Protection. How would you like even faster times on both GC and LC for emerging contaminants? During that same time period, overfuel releases were reported [1]. Are you more of a GC person? 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.

Since the beginning of the U. Eap said there is no free lunch? This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step.



pea National Environmental Monitoring Conference. For more information, see our privacy policy. In the chromatography world, a faster run time can easily be equated to improved productivity for your laboratory. 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.

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.

In this presentation, we will look at two environmental analyses where speed, sensitivity, and selectivity are of importance.

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. 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.

States that have published methods using fractionation are challenged with proper elution of these petroleum products. The 5-gram silica gel cartridge specified in these methods needs to achieve adequate separation of the two fractions with minimal interferences. 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.


Go to mobile site. Monitoring for the presence of PPCPs in drinking water has become of great interest 8015f to their ela impact on human health. Recent developments at Restek for some common challenging environmental samples will be presented by our environmental application experts.

In the first study, we analyzed the 20 target perfluorinated alkyl acids listed in EPA method. 815d allow for a variety of features that make your visit to Restek more enjoyable. Superficially porous particles SPP have been proven to epw fast and efficient separations with lower back pressures. By decreasing particle size, SPP particles offer even more efficiency than traditional fully porous particles of the same size.
