MS2Quant: Estimate the Concentration of Detected Chemicals from MS2 Data

Non-targeted screening is helping us to discover the complex chemical space of environmental samples. Due to the large number of detected chemicals, prioritization is necessary to direct focus on chemicals posing a risk to biota and humans. Commonly, key information for risk assessment is the exposure to the respective chemical. Unfortunately, the detected signal intensity is poorly […]

Which mobile phase I should use for my non-target LC/HRMS method?

Recently Amina Souihi in our group investigated the impact of mobile phase composition on the detection of various chemicals with non-target screening in wastewater. If you are using liquid chromatography (LC) coupled to mass spectrometry (MS) you have probably noticed that it is not equally easy to detect all chemicals. This arises from the fact […]
