Micans releases a new report cooperation with SKB

Uranine is a fluorescent dye that is used as a tracer for residues of drill water in groundwater investigations. This report examined whether Uranine gets degraded or affected by microorganisms.
When drilling in rock for groundwater fractures a large amount of drill water is used. To ensure that all the drill water has disappeared before starting investigations on the groundwater, tracers like Uranine is added to the drill water that fluoresces, i.e. glows when illuminated with light of a specific wavelength. If bacteria that live in the groundwater can affect Uranine to glow more or less, it is easy to overestimate or underestimate how much of the drill water is left. This was examined by Micans by adding Uranine to bacterial cultures with various species and then continuously measuring the fluorescence by spectrophotometry, and liquid chromatography (HPLC).
