Analysis of Petroleum Hydrocarbons C10-C40 in Water, Soil, and Waste with GC-FID This application note describes a process for the determination of total petroleum hydrocarbons in the range of C10-C40, with applicability to water, soil, and waste matrices; three standard methods are taken as a reference. Quantification of Low Levels of Hexavalent Chromium in Water Using a NexSAR™ Inert HPLC-ICP-MS This work demonstrates an ion exchange method for Cr6+ characterization in drinking water using our NexSAR HPLC-ICP-MS Speciation Solution. Discover the advantages of the inert and metal-free fluid path. Estrogen Monitoring in River Water by LC/MS/MS with Online SPE See how to utilize on-line solid phase extraction (SPE) coupled to an LC/MS/MS system for sample enrichment and quantitation of estrogen, allowing significant/efficient analyte concentration, obviating the need for time-consuming sample preparation procedures. Monitoring the Fate of Silver Nanoparticles in Seawater Using Single Particle ICP-MS 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 Method 8015C for Diesel Range Organics EPA 8015C is a gas chromatographic method. A Clarus® 690 GC was used for the analysis of petroleum hydrocarbons, specifically Diesel Range Organics (DRO).
