Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.

chemometrics was evaluated for the discrimination between nicotine containing and non-nicotine containing samples. It could be concluded that both ATR- IR and NIR could be used for the discrimination when ...

Non-surgical periodontal therapy with systemic antibiotics in patients with untreated aggressive periodontitis: a systematic review and meta-analysis.

Aggressive Periodontitis Amoxicillin Anti-Bacterial Agents Drug Therapy, Combination Humans Metronidazole Treatment Outcome Abstract: OBJECTIVE: The purpose of this meta-analysis is to evaluate the ...

ATR-FTIR spectroscopy and chemometrics: An interesting tool to discriminate and characterize counterfeit medicines.

evaluation of suspected samples. This study proposes a combination of ATR- FTIR and chemometrics to discriminate and classify counterfeit medicines. A sample set, containing 209 samples in total, was analyzed ...

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

and provide an adequate seal between the donor chamber and the membrane on which the sample is applied. Here, a simple and visual densitometer-based method is provided, which makes evaluation possible ...

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

characteristic function is used to describe the relation between the target concentration and the EQA standard deviation, which is an essential part of the evaluation process. The characteristic function is also ...

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 ...

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

SOFTWARE Abstract: BACKGROUND: The aim of this study was to evaluate the accuracy of linear measurements on three imaging modalities: lateral cephalograms from a cephalometric machine with ...

Detection of sibutramine in adulterated dietary supplements using attenuated total reflectance-infrared spectroscopy.

a need for easy to use equipment and techniques to perform an initial screening of samples. Attenuated total reflectance-infrared (ATR- IR) spectroscopy was evaluated for the detection of sibutramine in ...

Detection of whitening agents in illegal cosmetics using attenuated total reflectance-infrared spectroscopy.

attenuated total reflectance-infrared (ATR- IR) spectroscopy, combined with chemometrics, was evaluated for that purpose. It was found that the combination of ATR- IR with the simple chemometric technique ...
