Presentation of our Gas Chromatograph

In terms of gaschromatographically analysing our air simples, we are currently preparing several series of tests tests after having finished building it (see previous post "Improving our Gas Chromatograph").  As we have never had a gas chromatograph at school before, students, teachers and especially chemistry classes are very interested in this part of our secondary mission. Thus, we took the opportunity of giving a short presentation and answering all the questions that they had.
