Splet05. dec. 2013 · A full-mass scan was performed in the FT Orbitrap between 200–500 m/z at a resolution of 60,000, followed by ten MS/MS HCD scans of the ten highest intensity parent ions at 42% relative collision energy. The HCD scans were analyzed in the FT Orbitrap detector at a resolution of 7,500 and a mass range starting at 50 m/z. SpletThe balanced chemical equation tell us that, in theory, the number of moles of CaCO3 present in the sample is equal to the number of moles of CO2 produced. (This assumes a 100% percent yield for the reaction.) Thus the volume of CO2 measured leads to a value for the moles of CaCO3 present in the eggshell.
