Retention time is a crucial information for structural elucidation of unknown chemicals in non-targeted analysis using liquid chromatography coupled to high resolution mass spectrometry via electrospray ionization (LC/ESI/HRMS). Most of the predictive models of retention time are developed in limited chromatographic conditions, mostly for reversed phase and HILIC mode and in acidic conditions. However, retention […]
Masoumeh Akhlaqi is a Master student in analytical chemistry at Stockholm University. For her Master’s thesis, she is using two-dimensional ion mobility to separated, distinguish or identify isomeric compounds, specifically isomeric pesticides in food samples. For this purpose, she is using cyclic ion mobility instrument coupled to liquid chromatography and Time-of-Flight mass analyzer.
Pauline Petitfour is an intern from Sigma-Clermont engineering school in Clermont-Ferrand (France). She is studying organic and analytical chemistry and she is joining our group for four months internship. She will evaluate and model the extraction efficiency for most common solid phase extraction workflows used in non-targeted screening. Bienvenue Pauline!
Emma Palm and Louise Malm started their master thesis in our group. Emma and Louise are master students in analytical chemistry at Stockholm University and they did their bachelor’s thesis in our group. Emma Palm will work with cyclic ion mobility for the identification of isomeric compounds based on the collision cross-section. This will […]
