Determination of phytosterols in Oryza sativa L. cultivars by liquid chromatography atmospheric chemical ionization time-of-flight mass spectrometer (LC-APCI-TOF-MS) coupled with a modified QuEChERS method
Development of analytical methods for the determination of phytosterols in whole grains is one of growing interests due to their clinical and nutritional functions in human. In this study, we examined simultaneous determination of β-sitosterol, stigmasterol and campesterol in Korean rice cultivars by liquid chromatography atmospheric chemical ionization time-of-flight mass spectrometer (LC-APCI...
متن کاملSimultaneous Determination of 26 Mycotoxins in Sesame Butter Using Modified QuEChERS Coupled with UHPLC-ESI/Triple Quadrupole Mass Spectrometry Authors
This application note describes a method for the quantitative determination of 26 mycotoxins in sesame butter based on the work published by Liu et al. [1]. The sample was initially extracted and cleaned up using a modified QuEChERS protocol developed in the lab, and the resultant solution was subjected to separation and detection using an Agilent 1290 Infinity LC System coupled to an Agilent 6...
متن کاملDevelopment of a multi-mycotoxin analysis in beer-based drinks by a modified QuEChERS method and ultra-high-performance liquid chromatography coupled with tandem mass spectrometry.
An analytical method was developed for the identification and quantification of 15 mycotoxins (patulin, nivalenol, deoxynivalenol, aflatoxin B(1), B(2), G(1), G(2), M(1), T-2 toxin, HT-2 toxin, zearalenone, fumonisin B(1), B(2), B(3), and ochratoxin A) in beer-based drinks (beer, low-malt beer, new genre, and nonalcoholic) by a modified QuEChERS method and an ultra-high-performance liquid chrom...
متن کاملQuEChERS Sample Preparation for LC/MS and LC/UV Determination of Carbendazim and Other Conazole Fungicides in Orange Juice
IN T RODUC T ION QuEChERS methodology is commonly used for sample preparation of fruits and fruit juices, prior to LC/MS or other analytical chromatography. Recently, a nonregistered fungicide residue, carbendazim, was detected in orange juice purchased at a local market. This juice was produced from orange juice concentrate imported into the USA. In this application note, we discuss sample pre...
متن کاملUV photodissociation of trapped ions following ion mobility separation in a Q-ToF mass spectrometer.
An ion mobility mass spectrometer has been modified to allow optical interrogation of ions with different mass-to-charge (m/z) ratios and/or mobilities (K). An ion gating and trapping procedure has been developed which allows us to store ions for several seconds enabling UV photodissociation (UVPD).
