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...
متن کاملGc-ms and Gc-olfactometry Analysis of Aroma Compounds Extracted from Culture Fluids of Antrodia Camphorata
A comprehensive inventory of the organic components and aroma-active compounds produced by Antrodia camphorata during growth in submerged culture has been established by extracting culture fluids using three different organic solvent systems and subjecting the extracts to gas chromatography–mass spectrometry (GC–MS) and gas chromatography–olfactometry (GC-O). Forty-three organic components, of ...
متن کاملDetermination of odour concentration by TD-GC×GC–TOF-MS and field olfactometry techniques
ABSTRACT Field olfactometry is one of the sensory techniques used to determine odour concentration, in atmospheric air, directly in emission sources. A two-dimensional gas chromatography with time of flight mass spectrometer (GC×GC-TOF-MS) allows performing the chemical characterization of various groups of chemical compounds, even in complex mixtures. Application of these techniques enabled de...
متن کاملAnalysis of Odor‐Causing VOCs and Semi‐VOCs Associated with Particulate Matter in Swine Barns Using SPME‐GC‐MS‐Olfactometry
Swine operations can affect air quality by emissions of odor, volatile organic compounds (VOCs) and other gases, and particulate matter (PM). Particulate matter has been proposed to be an important pathway for carrying odor. However, little is known about the odor‐VOCs‐PM interactions. In this research, continuous PM sampling was conducted simultaneously with three collocated TEOM analyzers ins...
متن کاملAnalysis of Blood Alcohol by Headspace with Simultaneous GC-FID and MS
■ Introduction Determination of Blood Alcohol Content (BAC) has been a standard analytical method in criminal labs for many years. The typical instrument configuration consists of a static headspace instrument for sample introduction, followed by gas chromatography (GC) with two dissimilar capillary columns for separation, and two Flame Ionization Detectors (FIDs) for detection and quantitation...
