The petroleum industry appears to be making significant strides to improve the environmental stewardship and operational efficiency of energy production by implementing new technologies and capitalizing on previously wasted resources like produced water and flare gas. Nonetheless, many questions still remain about the management of aging or even abandoned infrastructure because abandoned production wells provide a potential for undocumented contamination events.

Decomposing animal tissue releases volatile organic compounds (VOCs), of interest in forensic science. We describe the use of GC×GC–qMS/FID retrofitted with a reverse fill/flush (RFF) flow modulator for analyzing these VOCs in a tropical climate.
Recently, the concept of environmental and social corporate governance (ESG) has received greater focus, particularly in the oil and gas industry. Its implementation offers opportunities for analytical chemists to help achieve greater sustainability.

In April 2020, on the heels of the pandemic shutdown, the price of crude oil fell to a negative value for the first time ever. The shutdown hit many oil and gas companies hard. But while companies lick their wounds and decide their next moves, an important concept called environmental and social corporate governance (ESG) has come greater into focus.

A highly sensitive method for quantitative determination of contaminants in surface waters, with and without particulate matter, was tested using stir-bar sorptive extraction (SBSE).
Uncovering the benefits of a system that hyphenates ion chromatography, titration, and direct measurement, in environmental analysis of water samples.
Exploring a new TD method capable of simultaneous analysis of compounds with a wide range of boiling points, high sensitivity, and high restore rates.

A hybrid HILIC–ion exchange column was used for the analysis of ultrashort-chain per- and polyfluoroalkyl substances (PFAS) compounds in environmental waters. This direct injection LC–MS method enables simultaneous measurement of ultrashort- chain, alternative, and legacy PFAS in potable and non-potable waters.
A comprehensive monitoring protocol has been developed using GC–MS/ECD in selective ion monitoring (SIM) mode, with injection performed by solid-phase microextraction (SPME) and headspace (HS). This single system has been configured to analyze for all taste and odor (T&O) compounds in Standard Method 2170, with minimal changing of columns, injectors, or SPME fibers between methods.
