Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills
analytical methods have been published for determining e-liquid compositions, but concerns exist with respect to the lack of analytical evaluation. Hence in this study, a new HS / GC- MS-based method was ...
Identification of a new tert-leucinate class synthetic cannabinoid in powder and "spice-like" herbal incenses: Methyl 2-[[1-(5-fluoropentyl)indole-3-carbonyl]amino]-3,3-dimethyl-butanoate (5F-MDMB-PICA).
chromatography with diode array detector (HPLC- PDA) and gas chromatography mass spectrometry (GC- MS) with computer based library search against spectral libraries. However, the most predominant compound in the ...

Pesticide Residues on Three Cut Flower Species and Potential Exposure of Florists in Belgium.
accredited laboratory using a multi-residue (QuEChERS Quick Easy Cheap Effective Rugged Safe) method and a combination of gas chromatography (GC) and liquid chormatograhphy (LC) analysis. A total of 107 active ...
Study of the possible migration risks of food contact materials for children under 3 years
dichloromethane (DCM)-n-hexane (1:1 and 1:3). The extracts resulting from the LLE step were analysed on GC-(EI) MS by monitoring specific ions for each analyte and for the internal standard. EtOAc-n-hexane (1:1) ...

Occurrence of polybrominated diphenyl ethers and emerging halogenated flame retardants in food items
performed using gas chromatography-mass spectrometry operated in electron-capture negative ionization mode (GC- ECNI / MS). The validated procedure was first used for the determination of BFR s in 20 ...
A survey of pesticide residues in cut flowers from various countries.
methods (GC- MS- MS and LC- MS- MS) in a laboratory accredited for pesticide residues. For all the samples analysed, a total of 97 active substances were detected, i.e. an average of 14 active substances ...
Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach
Therefore, when using a larger sample set including more possible sources of variation, more sophisticated detection techniques such as MS might be necessary. Chapter VIII describes the use of headspace- GC ...
