1121, Number 102 (2019) Keywords: Alkylphenol Bisphenol endocrine disruptor Paraben Placenta UHPLC-MS/MS Abstract: This study presents de development and validation of an ultra- high performance liquid ...
Open Lab Application for the Characterization of Nanomaterials by Transmission Electron Microscopy
more and more nanotechnology based products will become available in the European Union over the coming years, the European Commission (EC) has developed a Recommendation that provides a basis to ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
0.6-2.1 ng g−1 for BPF and from 0.8-1.3 ng g−1 for BPS. BPB and NP were not detected and OP levels ranged from 0.5-3.7 ng g−1. The results demonstrate that the developed analytical method is very sensitive ...
Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market
contaminated with those compounds by bees foraging PA producing plants. Downstream contamination can also occur through food items containing honey. Analytical methods based on UHPLC separation and MS / MS ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
Han, Zheng Source: Toxins, Volume 11, Issue 2, Number 100 (2019) Keywords: Alternaria toxins Grape modified QuEChERS UHPLC-MS/MS Abstract: A simple and reliable analytical method for the simultaneous ...
A more sensitive, efficient and ISO 17025 validated Magnetic Capture real time PCR method for the detection of archetypal Toxoplasma gondii strains in meat.
demonstrated. For this, a bioassay is still the reference method. As an alternative, various PCR methods have been developed, but due to the limited amount of sample that can be tested, combined with a low tissue ...
Development and performance assessment of a luminex xMAP® direct hybridization assay for the detection and identification of indoor air fungal contamination.
species identified with the classical method were also detected with the xMAP® assay, however in a shorter time frame. These results demonstrate that the Luminex xMAP® fungal assay developed in this study ...
Discrimination of three genetically close Aspergillus species by using high resolution melting analysis applied to indoor air as case study.
previously developed qPCR SYBR ®Green method to detect Aspergillus versicolor in indoor air, an important airborne fungus in terms of occurrence and cause of health problems. Despite the good performance ...
Nicotine Dependence and Urinary Nicotine, Cotinine and Hydroxycotinine Levels in Daily Smokers.
cigarettes per day among biomarker concentrations and individual FTND items. METHODS: Urine samples and questionnaire data of 239 daily smokers were obtained. Nicotine, cotinine and hydroxycotinine urinary ...
