Nicotine Dependence and Urinary Nicotine, Cotinine and Hydroxycotinine Levels in Daily Smokers.

levels were determined by UPLC MS / MS.Multiple linear regression models were developed to explore the relationship between nicotine, cotinine, hydroxycotinine levels and separate FTND scores (for all ...

Ecotoxicological potential of antibiotic pollution-industrial wastewater: bioavailability, biomarkers, and occurrence in Mytilus galloprovincialis.

chromatography-tandem mass spectrometry (UPLC- MS / MS) showed the presence of some antibiotic residues. These concentrations decrease to half in mussels treated with PW biodegraded by B. atrophaeus. Health Topics:  Food ...

Determination of caramel colorants' by-products in liquid foods by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).

liquid foods, an ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC- MS / MS) method was developed and sample preparation was divided into two analytical strategies depending on ...

Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.

tandem solid phase extraction using weak and strong cation exchange cartridges. Extracts were analysed by UPLC- MS (n) operating in the positive electrospray ionisation mode (ESI +). The fourteen dyes were ...
