“…A comparison between GC–TOFMS and quadrupole GC–MS using drug standards was carried out, which showed lower limits of detection (LODs) with GC–TOFMS similar to GC–electron capture detection. Furthermore, GC–TOFMS has the merits of high‐quality full‐scan mass spectra and high resolution (Aebi et al 2002; Bergknut et al 2006). A similar semiquantitative method was used for the determination of efavirenz and nevirapine in primary settling tank sludges from a WWTP using sonication extraction and GC–TOFMS analysis of samples collected in Gauteng, South Africa.…”

The sources, ecotoxicological impact, and potential remediation strategies of antiretroviral drugs (ARVDs) as emerging contaminants in surface waters are reviewed in this report based on recent literature. The occurrence of ARVDs in water bodies raises concern because many communities in Africa depend on rivers for water resources. Southern Africa is a potential hotspot regarding ARVD contamination due to relatively high therapeutic application and detection thereof in water bodies.Efavirenz and nevirapine are the most persistent in effluents and prevalent in surface water based on environmental concentrations. While the highest concentration of efavirenz reported in Kenya was 12.4 µg L -1 , concentrations as high as 119 µg L -1 and

“…The coupling of GC with MS is increasingly becoming the analytical tool of choice in this regard because of its superior selectivity and sensitivity. Among the most common analyzers including TOF [ 20 ], ion trap, and qMS [ 21 , 22 ], qMS is the most widely adopted technique for routine analysis of PAHs [ 23 ]. GC-qMS data acquisition takes advantages of both a full mass scan range (scan mode) and specific ion masses for target analytes (SIM mode).…”

Advanced separation technology paired with mass spectrometry is an ideal method for the analysis of atmospheric samples having complex chemical compositions. Due to the huge variety of both natural and anthropogenic sources of organic compounds, simultaneous quantification and identification of organic compounds in aerosol samples represents a demanding analytical challenge. In this regard, comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-TOFMS) has become an effective analytical method. However, verification and validation approaches to quantify these analytes have not been critically evaluated. We compared the performance of gas chromatography with quadrupole mass spectrometry (GC-qMS) and GC×GC-TOFMS for quantitative analysis of eighteen target polycyclic aromatic hydrocarbons (PAHs). The quantitative obtained results such as limits of detection (LODs), limits of quantification (LOQs), and recoveries of target PAHs were approximately equivalent based on both analytical methods. Furthermore, a larger number of analytes were consistently identified from the aerosol samples by GC×GC-TOFMS compared to GC-qMS. Our findings suggest that GC×GC-TOFMS would be widely applicable to the atmospheric and related sciences with simultaneous target and nontarget analysis in a single run.
