Analysis of PCBs and Organochlorinated pesticides in river water using simultaneous Scan/MRM measurement in GC-MS/MS

PCBs and some chlorinated pesticides are resistant to decomposition in the environment, and tend to accumulate in living organisms. As a result, they are designated as POPs (Persistent Organic Pollutants) under the Stockholm Convention. In monitoring these environmental pollutants in river water and sludge, sensitivity for the detection of trace quantities and separation from impurities in the ...

Adsorption and photocatalytic degradation of pharmaceuticals and pesticides by carbon doped-TiO2 coated on zeolites under solar light irradiation

To evaluate the performance of zeolite-supported carbon-doped TiO2 composite catalysts toward target pollutants under solar light irradiation, the adsorption and photocatalytic degradation of 18 pharmaceuticals and pesticides with distinguishing features (molecular size and volume, and photolysis) were investigated using mordenite zeolites with SiO2/Al2O3 ratios of ...

Novel composite photocatalyst made of TiO2 nanoparticles

A novel photocatalyst based on TiO2 nanoparticles was developed for application in fluidised bed photocatalytic reactors for water treatment. The mechanically robust photocatalyst consists of composite spheres made of TiO2 nanoparticles and TiO2 commercial powder. X-ray diffraction (XRD), scanning electron microscopy (SEM) and specific surface area analysis (BET) were used to characterise the ...

Target GC-MS Analysis using Accelerated Column Heating and Interactive Deconvolution Software

In diverse fields ranging from environmental samples to complex fl avor preparations, high performance, high resolution capillary gas chromatography/mass spectrometry, GC-MS, has become the preferred technique for identifying and quantifying target compounds at trace levels. Many of these samples are characterized by very complex matrices, which provide a substantial challenge for contemporary ...

Fast analysis of semi-volatile organic compounds using PTV-GC–TOF MS

The evaluation of semi-volatile organic compounds (SVOCs) in environmental matrices poses many challenges for the analyst, not least the vast number that may be encountered in any given analysis. In addition, analyte reactivity and the potential for multiple analytes to co-elute makes achieving the required method detection limits (LODs or MDLs) quickly and cost-effectively a formidable task ...

Proficiency test of non-target screening with gas chromatography mass spectrometry to confirm a detected contamination of raw and drinking water

Much of the water supply industry has implemented online monitoring and warning systems for chemical or biological contaminations. When a contamination is detected, further investigations are necessary to confirm or to cancel the initial alarm. The proficiency of a non-target screening approach with solid phase extraction and GCMS in full-scan mode was examined. A selection of pesticides and ...

LIMS and the Automation of the Water Lab

(Reproduced by permission from Laboratorium Magazine) Europe’s most modern water lab is located in Leeuwarden, in the Netherlands. Vitens made a big splash when it brought this modern building, with its transparent design, into operation in January 2005. Many colleagues from Dutch and foreign labs are eager to visit this installation, where water control samples are routed automatically with the ...
