In the chromatography world, a faster run time can easily be equated to improved productivity for 80155d laboratory. How would you like even faster times on both GC and LC for emerging contaminants? Recent developments at Restek for some common challenging environmental samples will be presented by our environmental application experts.
Are you more of a GC person? Who said there is no free lunch?
Download a PDF of the full presentation. 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.
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. Since the beginning of the U. During that same time ela, overfuel releases were reported . 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 was devised by the Massachusetts Department of Environmental Protection.

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. This work demonstrates a tuned EPH specific silica gel cartridge used to carry out this critical fractionation step. 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. Superficially porous particles SPP have been proven to provide 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.
In this presentation, we will look at two environmental analyses where speed, sensitivity, and selectivity are of importance. 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. Monitoring for the presence of PPCPs in drinking water has become of great interest due to their potential impact on human health.
Perfluorinated compounds are of concern due to their potential health effects and their persistence in the environment. In the first study, we analyzed the 20 target perfluorinated alkyl acids listed in EPA method. 0815d an attempt to expand the analyte list of concern ea 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.
