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.

Check Out Our Industry Pages! This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step. 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.
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. One of the earliest of these methods was devised by the Massachusetts Department of Environmental Protection. In the chromatography world, a faster run time can easily be equated to improved productivity for your laboratory. 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.
During that same time period, overfuel releases were reported . Cookies allow for a epaa of features that make your visit to Restek more enjoyable. Since the beginning of the U. A Company of Owners. How would you like even faster times on both GC and LC for emerging contaminants?
EPA Method 8015D (SW-846): Nonhalogenated Organics Using GC/FID
National Environmental Monitoring Conference. Who said there is no free lunch?
Optimized method-specific chromatograms will also spa presented. Download a PDF of the full presentation. Perfluorinated compounds are of concern due to epw potential health effects and their persistence in the environment. States that have published methods using fractionation are challenged with proper elution of these petroleum products. 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.

The 5-gram silica gel cartridge specified in these methods needs to achieve adequate separation of the two fractions with minimal interferences. Monitoring for the presence of PPCPs in drinking water has become of great interest due to their potential impact on human health. Currently viewing desktop site. Are you more of a GC person? While the federal 8105d 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.
