Discover Coiled microextraction and SPME field collection and injection devices using portable GC–MS for separation, detection, and identification of explosive materials.

Vitamin C is essential for the repair of tissue and is thought to lower cancer risk. This application brief describes use of a Quasar biphenyl column in this analysis.

Plavix tablets contain the active ingredient clopidogrel hydrogen sulphate, readily analyzed by HPLC. Use of a Quasar C8 column in the analysis of Plavix is described.

Detect whisky and spirits adulteration. Field-portable GC–MS provides rapid determination of denatured alcohol when added to spirit drinks to raise alcohol content.

This work demonstrates the ability of the NexION® ICP-MS, coupled to the dedicated Syngistix™ Nano Application software module, to measure silver (Ag) nanoparticles in seawater and track their transformations over time.

EPA 8015C is a gas chromatographic method used to establish concentrations of a variety of non-halogenated volatile organic compounds, semivolatile organic compounds, and petroleum hydrocarbons. For the purpose of this application, a Clarus® 690 GC was used for the analysis of petroleum hydrocarbons, specifically Diesel Range Organics (DRO).

Process for the determination of petroleum hydrocarbons in the range of C10–C40 in matrixes of water, soil, and waste, with three standards methods taken as a reference.

Ion exchange method for characterization of Cr6+ in potable drinking water using NexSAR HPLC-ICP-MS Speciation Solution. Discover advantages of the inert and metal-free fluid path

On-line solid phase extraction coupled to an LC–MS/MS system for sample enrichment and quantitation of endogenous estrogens allowing significant and efficient analyte concentration.

The FDA has made changes to how products containing sunscreen are labeled in the U.S. to ensure they meet the new regulations set forth for safety and effectiveness. The new regulations will require companies that want to use the "broad spectrum" label to test for both UVA and UVB protection.

The analysis of PAHs in less than 16 min using hydrogen as carrier gas and the PerkinElmer? Clarus? SQ 8 GC/MS operating in SIM mode is presented. Detection limits down to 0.5 pg on-column and a wide dynamic range are reported.
