GC-MS Analysis of Triglyceride. IV.

Chemical 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...

GC - 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...

Fluxome 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...

Analysis of Dithiocarbamate Pesticides by GC-MS

Introduction The class of dithiocarbamate fungicides (DTCs) is widely used in agriculture. They are non-systemic and both the formulation and their break-down products typically remain at the site of application. DTCs are characterized by a broad spectrum of activity against various plant pathogens, low acute mammal toxicity, and low production costs . The dithiocarbamate moiety is highly react...
