Contaminants in water: non-target UHPLC/MS analysis

Environmental Chemistry Letters, 2015
Contamination of water resources is one of the major problems to be faced for environment preservation and sustainability. The monitoring of target compounds based on mass spectrometry and selected reaction monitoring mode is often insufficient to definitely assess the quality of surface water.

Determination of carbapenems in water samples by UHPLC–MS/MS

Journal of Separation Science, 2020
AbstractA rapid and reliable method for the detection of five carbapenems (biapenem, imipenem, doripenem, meropenem, and faropenem) in water was developed and validated. After acidification of water samples with acetic acid, carbapenems were isolated using a Bond Elut PPL cartridge.

DI-004 BUSULFAN stability determination by UHPLC-MS

Drug information and pharmacotherapy, 2017
Background Busulfan is an alkylating antineoplastic drug extensively used in myeloablative regimens prior to haematopoietic stem cell transplantation. Administration every 6 hours for 4 consecutive days and the low stability of this product induces organisational problems for cytotoxic preparation units in hospital pharmacies.

Anatomical Characterization and UHPLC-MS Analysis of Hypericum vesiculosum

Revista Brasileira de Farmacognosia, 2020
In this study, we characterized Hypericum vesiculosum Griseb. (sect. Drosocarpium), Hypericaceae, a Balkan endemic and Greek subendemic species, which was collected from the Peloponnese (Greece). The anatomical study showed that its leaves are dorsiventral and hypostomatic, and the major part of its circular stem is filled with xylem.

Profiling of iridoid glycosides in Vaccinium species by UHPLC-MS

Food Research International, 2017
The iridoid profile of four Vaccinium species was investigated using UHPLC-MS to obtain further information about this group of species for phytochemical characterization. Fruits of bog bilberry (Vaccinium uliginosum L.) showed 14 different iridoid glycosides with a total amount of 20mg/kg fresh weight (FW), whereas bilberry (Vaccinium myrtillus L ...

Non-target UHPLC/MS Analysis of Emerging Contaminants in Water

2015
Contamination of water resources is one of the major problems to be faced for environment preservation and sustainability. Although anti-pollution strategies taken in the last half-century have consistently reduced in surface water the amount and the presence of many recognised contaminants, other potentially hazardous chemicals are being released into

Polyether ionophores residues in Minas Frescal cheese by UHPLC-MS/MS

Food Additives & Contaminants: Part B, 2020
An analytical method was developed and validated for the determination of three polyether ionophores (monensin, lasalocid, and salinomycin) in 60 samples of Brazilian Minas Frescal cheese by UHPLC-MS/MS. Linearity ranged from 1 to 8 μg kg-1 for monensin and salinomycin, and from 0.50 to 4 μg kg-1 for lasalocid. Limits of detection and quantitation were

Ruhemann’s Purple Monitoring by UHPLC/MS/MS for Ninhydrin Test

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi)
For amino acids used as food additives, Japan's Specifications and Standards for Food Additives stipulate the ninhydrin test as an identification test. The ninhydrin test is a simple method that involves the visual determination of purple color from the formation of Ruhemann's purple (RP) and does not require special equipment, facilitating its ...

Određivanje odabranih kanabinoida UHPLC-MS/MS tehnikom

2022
Kanabinoidi su spojevi koji se u posljednje vrijeme sve više istražuju radi svojih ljekovitih svojstava. Od osobite su važnosti nepsihoaktivni spojevi poput kanabidiola te njegovi derivati i metaboliti. Tekućinska kromatografija je jedna od najnaprednijih separacijskih tehnika u analitičkoj kemiji.

Characterisation of stilbenes in California almonds (Prunus dulcis) by UHPLC–MS

Food Chemistry, 2014
Stilbene polyphenols are present in some fruits and nuts, but their abundance in many foods, such as almonds, is unknown. Therefore, we characterised stilbenes from Nonpareil, Butte and Carmel almond (Prunus dulcis) varieties from California. UHPLC-MS conditions were optimised to resolve cis- and trans-resveratrol, d4-resveratrol, dienestrol, hexestrol,
