Advances in the characterisation and identification of mastic (Pistaciasp.) resin in archaeological samples by GC-QToF-MS

Abstract

A new analytical method based on GC-QToF-MS is proposed for the enhanced characterisation and identification of mastic (Pistacia sp.) resin in archaeological samples. New insights into the use of mastic in ancient Egypt are provided.

Pollution Characteristics and Ecological Impact of Screening Analysis of Fishing Port Sediments from Dalian, North China

“…17 In recent decades, GC-QTOF/MS has attracted much attention because of its high resolution, low detection limit, and good separation effect. 18 It has been successfully used for screening in different application areas, such as environmental analysis, food safety, and metabolomics. 19−21 The existing applications and future directions of nontarget analysis for emerging pollutants are worth considering.…”

“…The application of high-resolution mass spectrometry (HRMS), such as the combination of chromatography with time-of-flight mass spectrometry (TOF), has provided technical support for pollutant identification in marine environments. − However, the general analytical methods used in traditional environmental monitoring focus on the precise quantification of targeted compounds, most of which are based on pollutant priority lists. , At present, the methods used for pollutant screening include target, suspect and nontarget analyses. − Target analysis and suspect screening provide information about known parent compounds and known pollutants, and nontarget analysis based on unbiased detection is necessary to understand the full range of contaminants in samples .
