Effect of Matrix Clean-Up for Aflatoxin Analysis in Corn and Dried Distillers Grains
Aflatoxin LC-MS/MS Immunoaffinity SPE
2013/3/8
Aflatoxins are a group of highly carcinogenic mycotoxins that contaminate a wide variety of agricultural crops and have a detrimental economic impact on industries, such as corn and ethanol production...
Visualization of Spatial Distribution of γ-Aminobutyric Acid in Eggplant (Solanum melongena) by Matrix-assisted Laser Desorption/Ionization Imaging Mass Spectrometry
Visualization Spatial Distribution γ-Aminobutyric Acid
2010/9/14
We applied imaging mass spectrometry (IMS) to determine the spatial distribution of γ-aminobutyric acid (GABA). We found that GABA had a specific localization in seeds. We also visualized various biom...
MALDI Mass Spectrometry Using 2,4,6-Trihydroxyacetophenone and 2,4-Dihydroxyacetophenone with Cyclodextrins: Suppression of Matrix-related Ions in Low-molecular-weight Region
2,4,6-Trihydroxyacetophenone 2,4-Dihydroxyacetophenone Cyclodextrins
2010/9/14
Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry of a model peptide, Substance P (SubP), was carried out using 2,4,6-trihydroxyacetophenone (THAP) and 2,4-dihydroxyacetophenone (D...
Determining the Henry’s Law Constants of THMs in Seawater by Means of Purge-and-Trap Gas Chromatography (PT-GC): The Influence of Seawater as Sample Matrix
Law Constants Seawater Means Purge-and-Trap Gas Chromatography Sample Matrix
2010/9/13
The influence of seawater salts as salting out agents on the purge-and-trap gas chromatography (PT-GC) determination of trihalomethanes (THMs) was studied. This is particularly important since seawate...
