Last Thursday the HPLC2019 meeting finished. The conference was this year held in Milano, Italy and incorporated more then 300 talks. I had a chance to give a keynote lecture on the quantification of metabolites from green tea with LC/MS without the need for standard substances. The main focus of the conference was on the […]

Last week from 20th to 21th of May Tartu hosted Eurachem yearly workshop with the topic of “Validation of targeted and non-targeted methods of analysis”. These two days were filled with exciting presentations, insightful discussions and joy of meeting new and old friends and collaboration partners. What is happening in the field of non-targeted analysis? Eurachem […]

Today our master’s student Mari Ojakivi submitted her thesis. She studied the reactions between 7 aldehydes and 4 nitrogen bases in charged droplets. For this, she built an in-house built electrospray system to generate the charged droplets. Mostly imines were observed as reaction products, but also amides were found in some reactions. For comparison, the same reactions […]

We have now gathered our knowledge from years of ESI mechanism research and bundled it with data science to provide you with the possibility to quantify analytes in LC/ESI/MS analysis without the use of standard substances. The availability of standard substances is one of the main limitations in LC/ESI/MS analysis, especially in the fields […]

At the end of last year, our group got very happy news from Estonian Research Council, we received the personal research funding team grant to investigate synthesis in charged droplets (project abbreviation SNT). This new and exciting project allowed us to widen our team. In addition to masters student Mari Ojakivi, already working on the topic, Andi […]

Recently a study in Rapid Communications in Mass Spectrometry was published. In this study, we optimized the actual split ratio and make-up flow composition in LC/ESI/MS analysis to increase the signal in radio detector and enhance the sensitivity of electrospray ionization. High methanol content increases electrospray ionization efficiency We studied make-up flow composition with a […]
