Welcome to Kruvelab – meet Masoumeh

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.

Can we quantify chemicals if we do not know their structure? Yes, we can!

Non-target analysis with LC/ESI/HRMS is increasingly used to detect thousands of chemicals in environmental samples. However, most of these chemicals are never confidently identified nor quantified. This in turn means that they are ignored in risk assessments. In our recent paper, we address this issue by modeling the response factor for chemicals without the need […]

Welcome Lisa!

Lisa is a second year Master’s student with a background in environmental chemistry. For her Master’s thesis, Lisa is working on the exciting field of non-targeted screening and developing a prioritization method for unidentified compounds in the MS spectra of real life samples. In order to give compounds priority ranks, she is using in-house built […]
