Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
negative electrospray ionization. Labeled internal standards and matrix-matched calibration are used for quantification of the compounds. The method was validated according FDA guideline for bio analytical ...
Comparative dissolution study on substandard and falsified antibiotics encountered in Belgium
resistance and drug side effects [1]. In general, the evaluation of SF antimicrobials mainly focuses on the identification and quantification of the active pharmaceutical ingredients (API s), ignoring other ...
Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry
Keywords: Dried herbs gas chromatography Mass Spectrometry PAHs Spices Abstract: This paper describes a method for quantification of the four regulated polycyclic aromatic hydrocarbons (PAH ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
preparation of most quantification methods for e-liquids only consisted of simple dilute and shoot methodologies. In this study, we successfully developed a clean-up technique to eliminate most of the matrix ...
DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS
identified fragrance ingredient, illustrated in the acquired accuracy profiles. Conclusion: It is concluded that the optimized and validated GC- FID- MS method works well for identification and quantification ...
A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD
(e-liquids). Currently, the most important quality indicator of e-liquid products is the quantification of nicotine and its related impurities. Although different methods have been published to measure nicotine ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
negative electrospray ionization. Labeled internal standards and matrix-matched calibration are used for quantification of the compounds. The method was validated according FDA guideline for bio analytical ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
a screening and a quantification method using ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC- MS) and diode array detection (UHPLC- DAD), respectively were developed and ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
detection in the range of 0.03–0.21 μg kg−1, and limit of quantification in the range of 0.09–0.48 μg kg−1), and precision (relative standard deviation (RSD) ≤ 12.9%), the analytical method was successfully ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market
quantify a wide range of antimicrobials in suspected illegal products. In this work, a screening and a quantification method using ultra-high performance liquid chromatography with tandem mass spectrometry ...
