Post-Source Decay Spectra Using a Dual-Stage Reflectron. The discussion on coincidence techniques above suggests that the opportunities for recording product ion spectra on a reflectron instrument and the necessity for obtaining spectra at different reflectron voltages have been appreciated for some time. Nevertheless, the currendy popular technique known as post-source decay (PSD) is based upon an...

Mass calibration for instruments using dual-stage reflectrons is, of course, similar if one utilizes only those portions of the post-source decay spectra that are linear.
