In her final semester at Emmanuel, Ellie has been analyzing carbon dots synthesized from a mixture of urea and citric acid by teammate Gwyneth Gagnon. Ellie is working to understand the method of best separation for liquid chromatography, to gain knowledge about the properties of the carbon dots, such as size and polarity. Soon, she will run another synthesis of carbon dots that used ethylenediamine and then work on analysis using the LC-MS in negative polarity.
Ellie’s LC-MS instrument is pictured here! She’s running reversed phase separations with an ESI-single quad mass spec.
