Environmental Analysis

Separation Science, in collaboration with Agilent, is offering a selection of application notes demonstrating the versatility of its 8890 gas chromatography (GC) system that enables you to work smarter with autonomous monitoring, remote...

This study from SepSolve Inc. demonstrates the suitability of a TD–GC×GC system with dual TOF MS/FID detection for the routine, automated analysis of volatile organic compounds (VOCs) in complex air samples. 

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.

Volatile Organic Compounds (VOCs) can occur from natural sources such as plant scents. However, a large amount of VOCs do have an anthropogenic origin, because they are released from products in daily use or emitted during the manufacturing of...

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.
