Summer School: Automation and miniaturization in sample preparation

Two PhD students of our Analytical Chemistry Chair – Larissa and Ngan – recently attended an exciting Summer School: Automation and miniaturization in sample preparation, 13 – 15 September 2022, Charles University, Faculty of Pharmacy in Hradec Králové (Czech Republic).

Larissa: “The main topics of the summer school were supercritical fluid extraction (SFE), on-line solid phase extraction (SPE) in liquid chromatography, automation of extraction procedures in flow systems, and micro-SPE. Personally, the topics that stood out the most to me were SFE and micro-SPE, especially the latter, because of how straightforward, and yet tricky, this sample preparation technique is. In the afternoon workshops, we analyzed eucalyptus plant with SFE by varying some parameters (e.g., temperature, extraction time, etc.) and we were able to build our own pipette tip for micro-SPE. Apart from the great knowledge acquired, the summer school was well-organized, and I was able to meet and connect with people from different countries.“

Ngan: “Despite this was the first time the summer school was organized in the Department of Analytical Chemistry, I felt a warm welcome from the host. Professors from different fields at Charles University and Lund University made sure we all have take-home knowledge and demonstration of many techniques. My favorite part was about Extraction Disks, for example using Polycaprolactone – Graphene Nanoplatelets to preconcentrate the analyte. This is such a clever idea to minimize the sample preparation process and control lab waste.’’

Ngan and Larissa would like to thank FMTDK for the financial support.
