Matrix solid-phase dispersion associated to gas chromatography for the assessment in honey bee of a group of pesticides of concern in the apicultural field
(Elsevier B.V., 2018)
A method based on matrix solid-phase dispersion (MSPD) associated to gas chromatography-flame photometric detection (GC-FPD), GC-electron capture detection (GC-ECD) and GC-mass spectrometry (GC-MS) for confirmation purposes, ...
Matrix Effects on Water Analysis for Alkylphenols Using Solid Phase Extraction Gas Chromatography-Mass Spectrometry
(2013-11-01)
Gas chromatography with mass spectrometry is frequently used for the quantification of many classes of substances, including alkylphenols. Alkylphenol polyethoxylates are nonionic surfactants used in a wide variety of ...

Evaluation of pesticide adsorption in gas chromatographic injector and column
(Química Nova, 2018)
Matrix effect in pesticide analysis by ultra fast liquid chromatography coupled to mass spectrometry
In this work a study of several variables that affect the matrix effects (ME) was performed.
The choice was given among four extraction solvents and four different clean-up methods which
were compared in order to find ...
Purification and characterization of two β-glucosidases from the thermophilic fungus Thermoascus aurantiacus
(2002-12-01)
β-Glucosidase from the fungus Thermoascus aurantiacus grown on semi-solid fermentation medium (using ground corncob as substrate) was partially purified in 5 steps-ultrafiltration, ethanol precipitation, gel filtration and ...
