Environmental Analysis

Environmental scientists all have one thing in common… finding a reliable and reproducible method to uncover unknown contaminants and quantify known substances, even at ultra-low concentrations. We know that this can be quite a challenge.

This application note summarises the features of Markes’ thermal desorption (TD) systems that allow them to offer excellent performance for the analysis of semi-volatile organic compounds (SVOCs), including long-chain hydrocarbons, PCBs,...

In this application note, a method using a high selectivity triple quadrupole gas chromatography-mass spectrometer (GC–MS/MS) to detect for nonylphenol in river water is presented.

UCT has produced an application note to evaluate the effectiveness of the QuEChERS extraction and cleanup approach for the analysis of pesticides in soil.

This application note describes the performance of Markes’ thermal desorption (TD) systems for the GC–MS analysis of trace-level phthalates in air. 

Shimadzu has produced an application note describing a high sensitivity detection method for the detection of Pharmaceuticals and Personal Care Products (PPCPs) in surface water that does not require pre-treatment and concentration of water...

Shimadzu has produced an application note describing an MRM-based method for detection and quantitation of phenol and nine substituted phenols in reservoir water, without pre-treatment and pre-concentration.

Analysis times for semivolatile compounds can limit sample throughput and decrease overall lab productivity. In this technical article, an example of scaling down EPA Method 8270 and using a GC Accelerator kit to reduce cycle time is presented....

This study describes the performance features that enable Markes’ thermal desorption (TD) systems to be used for the GC–MS analysis of trace-level polychlorinated biphenyls (PCBs) in air.

In this presentation from an 'Advances in Environmental Analysis eSeminar' hosted by Separation Science in collaboration with Bruker, Ed George provides some tips on how to raise confidence in the analysis of environmental samples with tandem...

UCT has produced an application note describing the simultaneous analysis of pesticide residues and mycotoxins in cannabis using QuEChERS extraction. 

Biotage has produced an application note in which fifty semi-volatile compounds were concentrated using the new TurboVap^® II evaporator according to the EPA Method 625. For each of them, six replicates were done to assess the analyte recovery and...
