One variety of this technique uses the Xcorr score as a quality metric. This technique is the last step of MudPIT analysis, and the Orbitrap and FTICR are two different configurations of instruments used in it. One way to prepare the sample dissolves it in a liquid of low vapor pressure before bombarding it with high energy
One variety of this technique uses the Xcorr score as a quality metric. This technique is the last step of MudPIT analysis, and the Orbitrap and FTICR are two different configurations of instruments used in it. One way to prepare the sample dissolves it in a liquid of low vapor pressure before bombarding it with high energy xenon or argon atoms, called fast atom bombardment, or FAB. A gamma hydrogen may transfer to a carbonyl or an alkene during this technique via the McLafferty rearrangement. Molecules with a carbon 13 atom show an M+1 peak, while molecules with chlorine or bromine show isotope peaks. For 10 points, name this technique where a sample is zapped into fragments and separated by how heavy they are.
