Validation of a Targeted LC-MS/MS Method for Cereulide and Application in Food and Faeces.

food. This work aimed to develop and validate a targeted analytical method applying liquid chromatography-tandem mass spectrometry (LC- MS / MS) to quantify this toxin in food and human faeces. Samples ...

Development, validation, and application of a multimatrix UHPLC-MS/MS method for quantification of Datura-type alkaloids in food

spectrometry (UHPLC- MS / MS) method was developed and validated for the determination of tropane alkaloids (TA s), atropine and scopolamine, in a variety of food products. The sample preparation of cereal-based ...

Belgian recommendations for analytical verification and validation of immunohistochemical tests in laboratories of anatomic pathology

analysis taking into account the majority of variables regarding verification/validation of methods have been performed, resulting in an expert consensus recommendation that is a compromise between ...

Applicability of the DPRA on mixture testing: challenges and opportunities.

Keywords: Animal Testing Alternatives Animals Peptides Abstract: The in chemico direct peptide reactivity assay (DPRA) is validated to assess protein reactivity of chemical compounds, relating to the ...

The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.

available to the Belgian population, a method was developed for screening of 17 cannabinoids and to quantify the major cannabinoids such as CBD, CBDA, ∆9- THC and ∆9- THCA. The latter was fully validated ...

Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans

group worldwide, the microcystin congeners (MC s). After method validation, the quantitative UHPLC- MS / MS approaches were applied to Belgian samples to characterize potential human exposure sources in ...

COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS

method was developed using ultra-high performance liquid chromatography with diode array detector (DAD). Furthermore, selection of orthogonal wavelengths was made to extract maximum information from the ...

Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.

the approach not so straightforward. This paper aims to tackle this problem by developing a multidimensional chromatographic fingerprinting method aided by chemometrics. To render more specificity to ...

The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV

a method was developed for screening of 17 cannabinoids and to quantify the major cannabinoids such as CBD, CBDA, ∆9- THC and ∆9- THCA. The latter was fully validated using the ‘total error’ approach, ...
