Irja_Helm_Conducting_Dissolved_Oxygen_Measurement_Training_in_UruguayDuring Jun 12-16, 2017 research fellow Irja Helm from University of Tartu, Institute of Chemistry is conducting a training session on high-accuracy dissolved oxygen measurement in Montevideo (Uruguay). The local organiser of the training is LATU (Laboratorio Tecnológico del Uruguay). There are 8 participants in the training, from Uruguay, Argentina, Ecuador and Peru.

The training is centered around the high-accuracy Winkler titration method of dissolved oxygen concentration measurement that Irja developed during her PhD study: I. Helm, L. Jalukse, I. Leito “A highly accurate method for determination of dissolved oxygen: Gravimetric Winkler method” Analytica Chimica Acta 2012, 741, 21–31. The training is interesting in the sense that most of it is carried out in laboratory, where participants do measurements hands-on. The experimental setup was assembled jointly by LATU and by Irja. The practical orientation is well in line with the main purpose of the training – to introduce the high-accuracy Winkler method to the reference laboratories in the participant countries.

The training is organised in the framework of the project „Regional Quality Infrastructure Fund for Biodiversity and Climate Protection in Latin America and the Caribbean“ (VH-No.: 95094) coordinated by PTB (Germany).
