Abstract [en]

The aim of this paper is to document the development of a method for detectionand quantification of Polychlorinated biphenyls (PCB) in soil using GasChromatography (GC) connected to a Quadrupole Mass Spectrometer (MS) via aninternal standard (CB189). The method developed is performed in conjunction withthe information provided by the Swedish environmental agency (Svenskanaturvårdsverket, SNV) in regards to PCB limits for sensitive land usage. The steps ofthe method and maintenance of the GC/MS are used to create a user manual andan attempt at transformative learning is done in an effort to teach the staff atLjungaLab AB so that at the very least, independent analysis can be run and at best,new methods and application are independently developed for the GC/MS. Anevaluation of the teaching efforts is also done to assess what grade of learning isachieved.

Abstract [sv]

Syftet med denna uppsats är att dokumentera utvecklingen av en metod fördetektion och kvantifiering av polyklorerade bifenyler (PCB) i jord med hjälp avgaskromatografi (GC) ansluten till en masspektrometer (MS) och med användningav en intern standard (CB189). Metoden som utvecklats skapades med hjälp avuppgifter från det svenska naturvårdsverket (SNV) angående PCB-gränser för känsligmarkanvändning. Därefter skapades en användarmanual som beskriver stegen imetoden och även underhåll av GC/MS. Personalen på LjungaLab AB undervisadesi hur man använder och underhåller instrumenten för att, åtminstone, kunna köraoberoende analyser, och i bästa fall, utveckla nya metoder och tillämpningarsjälvständigt. Det sistnämda är ett försök till transformativ lärande. En utvärdering avlärarinsatser sker också för att bedöma vilken grad av lärande som uppnås.
