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 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 ...
