Chromatography in the detection and characterization of illegal pharmaceutical preparations.

for analytical laboratories to detect and characterize them. Spectroscopic techniques such as infrared spectroscopy and Raman spectroscopy have always been the first methods of choice to detect ...

Development and validation of a fast chromatographic method for screening and quantification of legal and illegal skin whitening agents.

To control this market there is a need for a fast screening method capable of detecting illegal ingredients in the wide variety of existing bleaching cosmetic formulations. In this paper the ...

A validated GC-MS method for the determination and quantification of residual solvents in counterfeit tablets and capsules.

Temperature Time Factors Abstract: A fast headspace GC- MS method was developed and validated for the detection and quantification of residual solvents of all three ICH-classes in counterfeit tablets and ...

Comparison of different approaches to evaluate External Quality Assessment Data.

similarly for sample sizes above 10 and when outliers were at good distance from the centre. For smaller sample sizes and closer outliers, however, the approaches performed quite differently. Tukey’s method ...

A validated Ultra High Pressure Liquid Chromatographic method for the characterisation of confiscated illegal slimming products containing anorexics.

A fully validated UHPLC- DAD method for the identification and quantification of pharmaceutical preparations, containing molecules frequently found in illegal slimming products (sibutramine, modafinil, ...

A validated ultra high pressure liquid chromatographic method for qualification and quantification of folic acid in pharmaceutical preparations.

A fully validated UHPLC method for the identification and quantification of folic acid in pharmaceutical preparations was developed. The starting conditions for the development were calculated starting from ...

A new statistical method for evaluating long-term analytical performance of laboratories applied to an external quality assessment scheme for flow cytometry.

past 3 years. This study aims to develop a method to find laboratories with aberrant variability or bias using robust techniques and to obtain robust estimates of the variability. METHODS: A method is ...
