Last week two of our PhD students, Piia Liigand and Jaanus Liigand, successfully defended their PhD theses. Both Piia and Jaanus worked intensively and successfully on understanding the ionization process in electrospray ionization source (ESI) and applying this knowledge for quantifying compounds with LC/ESI/MS without standard substances. Congratulations to the fresh doctors! Piia is continuing […]

Ionization efficiency of oligopeptides does depend on the chemical composition of the peptide. Longer oligopeptides generally obey higher ionization efficiency; however, for peptides containing more than seven amino acid the ionization efficiency values are relatively similar. Also, the ionization efficiency values of the amino acids can be used to estimate the ionization efficiency of a […]
