Characterizing All 136 Tetra- to Octachlorinated Dioxins and Furans

Using the Rtx®-Dioxin2 Column

The Rtx®-Dioxin2 column has a unique selectivity for dioxins and furans, including specificity for 2,3,7,8-TCDD and 2,3,7,8-TCDF. Here we characterize all 136 tetra- through octachlorine dioxins and furans and define all possible coelutions. While commonly used cyanopropyl columns are limited by a low maximum operating temperature of 240°C, the Rtx®-Dioxin2 column is stable up to 340°C, extending column lifetime and improving the analyses of dioxins and furans. | Find out more

Complete Resolution of Benzene from Ethanol in Spark Ignition Fuels

Using a Modified ASTM D3606-06e1 Method and Rt™-D3606 Column Set

If you have concerns about analyzing reformulated fuels containing ethanol, our new two-column set is the solutionit completely resolves benzene from ethanol. The aromatic compounds, too, are fully resolved, and can easily be quantified, using sec-butanol as an internal standard. The robust column set is ready to use after only a 10 minute carrier gas purge at ambient temperature, followed by a 30 minute hold at 165°C. | Find out more

Achieve Faster Analyses on Any HPLC System Using Ultra II™ Columns

Significant savings can be obtained without the costly upgrade to UHPLC. This famotidine example illustrates how a 90% reduction in analysis time and solvent volume resulted from strategic HPLC column choices. | Find out more

Comprehensive Pesticide Residue Analysis by LC/MS/MS

Analysis of pesticide residues in foods is complicated by the large number of target compounds. LC/MS/MS analysis using an Aqueous C18 column provides more comprehensive results than GC alone. | Find out more

5 Minute Analysis of Vitamin D in Serum by LC/MS/MS

Conventional techniques for vitamin D analysis often lack adequate sensitivity, specificity, and speed. This LC/MS/MS assay results in highly symmetric peaks that elute in just 5 minutes.
