MSACL EU 5th Annual Congress & Exhibits in Salzburg

From the 9th to the 13th of September MSACL EU 2018 Annual Congress took place in the cosy city of Salzburg, Austria. This conference was designed to mass spectrometry audience mainly focusing on clinical applications.  I had the opportunity to participate in this inspiring conference. Moreover, I had the possibility to give a talk. I introduced our studies on […]

Prediction of ionization efficiencies in biological matrices

In the recent years, we have made significant progress in ionization efficiency studies. In our previous publications, we have shown that our approach can be applied in both electrospray positive and negative mode (we have recently also enabled comparing the logIE values measured in both ESI modes numerically), that our approach is transferable between different […]

What can we learn from mass spectrometry about charged droplets?

Charged droplets occur everywhere in the world. They are created by the oceans (known as see spray aerosols), near waterfalls and in thunderstorm clouds. Such droplets are expected to play significant role in environmental processes. Similar droplets are also created in electrospray ionization (ESI) source. Mari Ojakivi joined our group three years ago to conduct […]

Choosing analyses conditions to get matrix effect free?

Recently my first single-authored paper became public. It concerns the solvent effect on electrospray ionization efficiency and matrix effect. As we have talked about ionization efficiency and its solvent effects also previously, let’s focus on matrix effects this time. As LC/ESI/MS is the tool for various fields in routine analyses (quality control over pesticides but also mycotoxins in the food we eat, drug monitoring […]
