The use of Stationary Phase Optimized Selectivity Liquid Chromatography for the development of herbal fingerprints to detect targeted plants in plant food supplements.
therefore be concluded that the combination of segments of different types of stationary phases, as used in SOS- LC, has the potential of becoming a valuable tool in the quality control and the identification ...
Characterization of suspected dermal fillers containing hyaluronic acid
validation of a specific identification and quantification method is described. The proposed method utilizes an essential pre-extraction step prior to identification by infra-red spectroscopy followed by an ...
Chromatographic fingerprinting as a strategy to identify regulated plants in illegal herbal supplements.
is not a simple task since plants are often crushed and mixed with other plants, which complicates their identification by usage of classical approaches such as microscopy. The aim of this study was to ...
An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.
fractionation for this purpose. Sample fractionation proved mandatory to enable identification of plasma residuals. Two approaches were compared: Ig depletion with protein G — protein A affinity chromatography ...
Inter-laboratory study of human in vitro toxicogenomics-based tests as alternative methods for evaluating chemical carcinogenicity: a bioinformatics perspective.
