In vitro Dermal Absorption: Sample Application and Seal Quality in a Franz Diffusion Cell System.

known drawbacks of in vitro dermal absorption methods is their high interlaboratory variation. Although often attributed to biological skin differences, it has been shown that validation of other ...

Application of the characteristic function to evaluate and compare analytical variability in an external quality assessment scheme for serum ethanol.

analysis Abstract: BACKGROUND: As a cornerstone of quality management in the laboratory, External Quality Assessment (EQA) schemes are used to assess laboratory and analytical method performance. The ...

External Quality Assessment for the Detection of Chlamydia trachomatis in Urine Using Molecular Techniques in Belgium.

low concentration samples and the incapacity of several methods to detect the Swedish variant of C. trachomatis. The reassuring point was that the overall proficiency of the Belgian laboratories tended ...

How appropriate is therapeutic drug monitoring for lithium? Data from the Belgian external quality assessment scheme.

concentrations. The present study aimed to assess the appropriateness of lithium assays used by Belgian laboratories, and to evaluate acceptability of their clinical interpretations. METHODS: Nine in-house serum ...

Development of a Stationary Phase Optimised Selectivity Liquid Chromatography based screening method for adulterations of food supplements for the treatment of pain.

analgesics, a heterogeneous group of molecules, containing both hydrophilic and hydrophobic compounds. The development of a screening method for these components, especially when mass spectrometric detection is ...

Accuracy of linear measurements using three imaging modalities: two lateral cephalograms and one 3D model from CBCT data.

a 3 m source-to-mid-sagittal-plane distance (SMD), from a machine with 1.5 m SMD and 3D models from cone-beam computed tomography (CBCT) data. METHODS: Twenty-one dry human skulls were used. Lateral cephalograms were taken, using two ...

HS-GC-MS method for the analysis of fragrance allergens in complex cosmetic matrices.

combined with a new headspace GC- MS method. The latter was capable of analysing 24 volatile allergenic fragrances in complex cosmetic formulations, such as hydrophilic (O/W) and lipophilic (W/O) creams, ...

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 ...
