Simultaneous quantification of Ibuprofen and Paracetamol in combined tablet formulations by UV–VIS spectrophotometry and chemometric modelling

prior separation, thus simplifying sample preparation and reducing waste generation, time and cost of analysis. The aim of this work was to develop reliable and robust chemometric models coupled with UV ...

Mass Spectrometric Fingerprinting to Detect Fraud and Herbal Adulteration in Plant Food Supplements

full three-dimensional dataset (i.e., time × intensity × mass) obtained with liquid chromatography hyphenated with MS for herbal fingerprinting purposes. The MS parameters were optimized to achieve ...

Characterisation and Hazard identification of substandard and Falsified Antimicrobial Drugs. The CantiBio project 2016-2020

the amount of drug released is under the limit at the time point described by the USP. In addition to that, low equivalences of dissolution profiles between SF antimicrobials and genuine products were ...

Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements

× time points) were used for selection of orthogonal wavelengths by conducting a correlation analysis. After preparation of triturations, recording of the fingerprints and creation of datasets (corrected ...

COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS

corrected for time shifts using correlation optimized warping and further pretreated using classical techniques like signal noise variate, autoscaling and derivatives), before being subjected to partial least ...

Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.

the chromatogram, a multidimensional fingerprint (absorbance × wavelength × retention time) was considered. This was achieved by selecting several wavelengths through a correlation analysis. The data ...

Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements

nm, which is useful for visual inspection. In a second step, mass spectrometric (MS) measurements using a time of flight analyzer were performed. This was done in order to further confirm the presence ...

Nine prohibited stimulants found in sports and weight loss supplements

liquid chromatography (UHPLC) quadrupole-Orbitrap mass spectrometry. RIVM performed qualitative and quantitative analysis using UHPLC quadrupole time-of-flight mass spectrometry. Sciensano carried out ...
