Detection and Identification of Dispersants (COREXIT® 9527 and 9500) by GC/MS and LC-MS/MS

Dispersants are plasticizers commonly used to prevent clumping and help dissipate oil slicks. In this work, we used GC/MS and LC-MS/ MS to detect and indentify two of the most widely used dispersants (Corexit 9527 and 9500).

Detection of Environmental Contaminants Caused by the Oil Spill in the Gulf of Mexico by GC and HPLC

In order to help understand the impact that the oil spill has caused, laboratories are looking for rapid and robust analytical procedures to characterize the hydrocarbon contaminants. This work provides SPE, GPC, GC-FID, GC/MS, and HPLC analytical methods for analyzing the most common contaminants that originated from the leak.

Trace Analysis of Isothiazolinones in Water Samples by Large-Volume Direct Injection Liquid Chromatography Tandem Mass Spectrometry

Isothiazolinones are used as preservatives, biocides and desinfectants in variety of industrial and domestic applications. The purpose of this study was to develop and optimize an LC–MS/MS method that would enable the determination without any derivatization or preconcentration step of isothiazolinones used in membrane technology for water purification and in household products, at levels relevant for the water cycle.

Reversed-Phase Point-of-use Purifier for the Removal of Trace Organics in High Purity Water

Recent developments of Liquid Chromatography instrumentation, such as UHPLC coupled with mass spectrometry, have increased the separation efficiency and sensitivity. Unfortunately, there are some unwelcome consequences. One of these is the detection of trace contamination in the solvents used to prepare mobile phases. The aim of this work was to design a cartridge which produces high water quality for very sensitive LC-MS applications.

Hyphenated Techniques as Modern Detection Systems in Ion Chromatography

Historically ion chromatography (IC) using conductivity detection has been successfully used for the analysis of ionic (e.g., anions and cations) and polar substances (e.g., organic acids or sugars). However, due to current toxicity concerns, analyses in complex matrices require improved sensitivities and selectivities.
