Replacing Multiple 50-Minute GC and GC-MS/SIM Analyses with One 15-Minute Full-Scan GC-MS Analysis for Nontargeted Pesticides Screening and >10x Productivity Gain Application
Pesticide analysis of fruits and vegetables requires finding trace-level residues in complex matrices. Up to now, the typical trade-off is between sensitivity and confirmation. Therefore, multiple injections are needed for screening and confirmation using gas chromatography with mass spectrometry (GC-MS) or GC-MS in combination with GC with element-selective detection. With the recent introduct...
متن کاملChemical Analysis of Pesticides Using GC/MS, GC/MS/MS, and LC/MS/MS
There are well over 500 registered pesticides worldwide for use in agricultural regions and new agrochemicals are introduced to the marketplace continuously. This chapter deals with the chemical analysis methods for the main pesticide chemical classes that are most frequently analyzed with gas chromatography (GC) or liquid chromatography (LC) coupled to mass spectrometry (MS). GC amenable pesti...
متن کاملFluxome analysis using GC-MS
Fluxome analysis aims at the quantitative analysis of in vivo carbon fluxes in metabolic networks, i. e. intracellular activities of enzymes and pathways. It allows investigating the effects of genetic or environmental modifications and thus precisely provides a global perspective on the integrated genetic and metabolic regulation within the intact metabolic network. The experimental and comput...
متن کاملGC - MS analysis of Polygala
The present study presents the bioactive profile of Polygala arillata Buch.-Ham ex D.Don using GC-MS. The phytochemical constituents of leaf and stem ethanolic extracts of Polygala arillata were investigated using Fisons Gas-chromatography – Mass spectrometry. The mass spectra of the compounds in the leaf and stem extracts was matched with National Institute of standards and Technology (NIST) L...
متن کاملAnalysis of GC-MS metabolomics data with metaMS
Many packages are available for the analysis of data from GC-MS and LC-MS experiments – typically, hardware vendors provide software that is optimized for the instrument and allow for a direct interaction of the lab scientist with the data. For high-throughput applications, however, more automatic pipelines are needed. Open-source alternatives such as xcms [1] not only are able to handle data f...
