Chemical and toxciological characterization of e-liquid cigarettes
the revised TPD. The samples were examined for the presence of nicotine, nicotine-related impurities, volatile organic compounds, caffeine, taurine and the harmful flavours diacetyl and acetylpropionyl. ...
Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium
a subsequent quantification method using ultra-high performance liquid chromatography with diode array detection (UHPLC- DAD) was also successfully validated. Next, real-life illegal antimicrobial samples ...
Chemometrics and chromatographic fingerprints to discriminate and classify counterfeit medicines containing PDE-5 inhibitors.
genuine and counterfeit samples of Viagra(®) and Cialis(®) were evaluated for their use in the detection and classification of counterfeit samples of these groups of medicines. Therefore several exploratory ...
Classification trees based on infrared spectroscopic data to discriminate between genuine and counterfeit medicines
method methods MODEL models ON Order public public health Public-health regression Sample Samples System Technique use world Abstract: Due to the extension of the internet, counterfeit drugs represent ...
Comparison of different approaches to evaluate External Quality Assessment Data.
Value of Tests Quality Assurance, Health Care Sample Size Abstract: In EQA programs, Z-scores are used to evaluate laboratory performance. They should indicate poorly performing laboratories, regardless ...
Detection of counterfeit Viagra® by Raman microspectroscopy imaging and multivariate analysis.
8 genuine tablets of Viagra® were analysed by Raman microspectroscopy imaging. After unfolding the data, three maps are combined per sample and a first PCA is realised on these data. Then, the first principal ...
Impurity fingerprints for the identification of counterfeit medicines--a feasibility study.
were treated like fingerprints representing the quality of the samples. A total of 73 samples of counterfeit and imitations of Viagra(®) and 44 samples of counterfeit and imitations of Cialis(®) were ...
Comparison and combination of spectroscopic techniques for the detection of counterfeit medicines.
IR), near infrared spectroscopy (NIR) and Raman spectroscopy were applied to 55 samples of counterfeit and imitations of Viagra and 39 samples of counterfeit and imitations of Cialis. The aim of the ...
A new statistical method for evaluating long-term analytical performance of laboratories applied to an external quality assessment scheme for flow cytometry.
samples with different target values. Outliers in the first step indicate accidental mistakes, outliers in the second and third step point to high analytical variability or bias. Health Topics: ...
Current practices in antinuclear antibody testing: results from the Belgian External Quality Assessment Scheme.
Luxembourg laboratories, using the results obtained in the Belgian National External Quality Assessment Scheme from 2000 to 2005. METHODS: During this period, nine samples with different specificities were ...
