Development in fission track-thermal ionization mass spectrometry for particle analysis of safeguards environmental samples

Fission Fragment Ionization Mass Spectrometry of Chlorophyll a

The title study has been made by using a time-of-flight mass spectrometer, placing primary emphasis on fragmentation reactions and rates. The mass spectrometer was modified so that segmented fields with segments of different magnitudes could be applied in the ion acceleration region and retarding potentials in the region between the flight tube and the ion detector. Methods using these retardin...

Operational options to reduce matrix effects in liquid chromatography-electrospray ionization-mass spectrometry analysis of aqueous environmental samples.

Matrix effects like signal enhancement or suppression can severely compromise quantitative analysis of environmental samples with liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS). Several operational options were studied to reduce such matrix effects in the determination of polar organic trace contaminants from water, like non-steroidal anti-inflammatory drugs, among ...

Analyte migration electrospray ionization for rapid analysis of complex samples with small volume using mass spectrometry.

Complex biological matrices can be effectively removed in the analyte migration process because of their weak solubility in organic solvents. This technique offers other potential advantages, including high-sensitivity and the capability of performing a direct analysis of the components and their metabolites in small-volume raw samples without any pretreatment.

Tandem Mass Spectrometry of Alkanolamines in Environmental Samples

Alkanolamines are anthropogenic compounds used extensively not only in the processing of sour natural gas but in other operations such as the petrochemical and fossil-fuel fired industries to reduce and prevent the emission of green house gases into the environment. Alkanolamines also find uses as corrosion inhibitors, emulsifying agents and in pharmaceutical formulations (Dobberpuhl and Johnso...
