and product qualification. Challenges – Manufactures are sometimes faced with the challenge to select, produce and qualify suitable standards for their intended use. Ideally, international ...
THE ANALYSIS OF ILLICIT DRUGS COLLECTED DURING A SUMMER FESTIVAL AND EVALUATION OF THE NARCOREADER FOR ON-SITE ANALYSIS OF MDMA
spectroscopic methods with as a downside the lack of accuracy and selectivity. The law still requires confirmation of these results with chromatographic methods. These conventional methods are precise but ...

Spectroscopic approaches for conformity analysis of e-liquids
taurine, vitamin E and CBD in e-liquids. Therefore a set of 236 e-liquids was selected. Since samples with caffeine, taurine, CBD and vitamin E as additives were hard to find, some of the samples were split ...
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 ...
